Do humans have sensory cells inside their body like the ones we have on our skin?
969505
Yes, the human body has similar sensory cells inside the body. However, there are also many other types of sensory cells inside us that aren't like the ones on our skin. Some of the cells in certain places (the large and small intestine, for example) are only sensitive to stretch, and are essentially numb to lacerations or other stimuli. Likewise, infections in certain areas (GI tract, once again) are often not noticed until other areas with different kinds of nerves become infected (such as the peritoneum). Basically, the answer to the question is yes, we have sensory cells similar to skin ones, and no, we have other kinds as well.

There are many different type of sensory receptors for telling different stimuli apart. So the ones that sense pressure on your skin are different from the ones that detect heat. Your retina has receptors for different wavelengths of light, your tongue has different receptors for different tastes, and so on. From there, information is transfered to afferent neurons which send the signal up to your brain. There is a labeled-line principle which basically states that each sensory neuron corresponds to a specific part of the brain. So when that area is stimulated, the brain "knows" what, where, intensity, etc.

From the link below:\n\nThe average human body is covered by about 20 square feet (2 square meters) of skin. Skin is the only organ that is constantly exposed to potential irritation. And, with so many things coming into contact with your skin daily, you're bound to get an itch or two. Serious itching can be caused by allergies, disease, emotions and infections, but let's take a look at what causes the common itches that aggravate you everyday. \nItching, also known as pruritus, starts with some kind of external stimuli, including bugs, dust, clothing fibers and hair. Like tickling, itching is a built-in defense mechanism that alerts your body to the potential of being harmed. In this case, it might be the potential of being bit by a bug. \n\nWhen the stimuli lands on your skin, it may not bother you at first, but soon it will begin to rub back and forth across your skin. Once the hair or dust scratches your skin's surface layer, receptors in the dermis of the skin will become irritated. In a split second, these receptors send a signal through fibers in the skin to your spinal cord and then up to the cerebral cortex in your brain. \n\nThe same fibers that send itching signals are also used to send pain signals to the brain, which once led some scientists to believe that itching was a form of light pain. That notion has since been dispelled by research, which showed that pain and itching elicit opposite responses. Pain causes us to withdraw and itching causes us to scratch. \n\nAs soon as we feel an itch, our first natural response is to scratch the spot of the itch with our fingernails. The reason for this response is simple -- we want to remove the irritant as soon as possible. Once you've scratched the area of irritation, you are likely to feel some relief. When your brain realizes that you've scratched away the irritant, the signal being sent to your brain that you have an itch is interrupted and therefore no longer recognized by the brain. \n\nEven if you don't remove the irritant, scratching will at least cause pain and divert your attention away from the itching. The irritant that caused the itching is very small, maybe only a few microns in length, so it disturbs only a few nerve endings. When you use your fingernail to scratch the spot where the irritant is, you not only remove the irritant but you irritate a lot more nerve endings than the irritant.

They don't have a nervous system.  They do have chemical and tactile sensors, as well as chemical messengers that cause actions in response to stimuli.  For example, a mimosa plant will fold up in an attempt to protect itself if touch it with your finger.

there might be other creatures that we are not capable of seeing, some call them ghosts, or demons or spirits. We are limited the 5 senses to sense the world around us.\nWe know dogs can hear different frequencies that us, they also have different senses, some say they can see ghosts or other invisible things to us. \nImagine if all human didn't have eyes and could not see, we would have no consept of color, we would not know the difference between day or night. same thing now, if we had "other" senses we could've seen or sensed new and different things that currently we have no understanding to it.\n\nI think the ghosts interact with us and we sense them but we usually think it is our gut feelings.

Elasmobranchs (sharks, skates, and rays) indeed have an interesting sensory physiology enabling them to sense a variety of physical stimuli.  But fear is not one of them. That said, it is true though that fear may be associated with either the release of particular chemical compounds, but far more importantly and likey in regards to your question, with particular behavior.  And in that sharks are not very different from any other predator.\n\nThe sense of smell is indeed very well established in almost all elasmobranchs; if you ever take a look at a shark's brain note the extremely large bulbi olfactorii, the areas of the brain where smell is first analyzed.  The sentivity of shark noses for blood is often emphasized, but you must not imagine sharks to be "swimming noses."  Rather, they rely on different senses for different environmental conditions, prey, etc. The priority assigned to either one of the possible sensory modes is largely dependent on the life-style of the animal.  Given that there are over 400 different species, there are a few variations.\n\nLike many other aquatic animals (e.g., teleosts, but also amphibians) sharks rely on their lateral line organ for detecting objects in greater distances.  The lateral line organ is a tiny canal running along the side of the animal underneath the skin.  it is open to the environment through a set of pores, through which the shark can sense pressure differences in the water, as they are being produced for example by a fish in distress.  This can of course be misunderstood as "smelling fear," when in fact it is more like "sensing the panicked movements of a potential prey."\n\nThe electromagnetic sense of elasmobranchs is perhaps most amazing from a human point of view, since it is so very different from anything we have.  All elasmobranchs have Ampullae of Lorentzi, with which the animals can indeed sense bioelectric fields.  These organs are so sensitive that a dogfish can sense the bioelectric field induced by the beating heart of a flounder covered by sand.  Sharks also use this organ for a magnetic compass.  By swimming through the earth's magnetic field, a shark will induce an electric current that will either run from its back to its belly (when the animal swims in an eastern direction), or from its belly to its back (in western direction).  with its own electromagnetic sensores, the animal can sense the induced electric current and its direction and can thus orient itself along the magnetic field of the earth.  Again, very sexy and very helpful, but no detector of fear!\n\nNow, some sharks use their eyes when they hunt prey, and this may an important point in regards to your question.  Great white sharks (Carcharodon carcharias) often attack their prey (e.g., seals) from far below, orienting themselves visually in their attack and going for the tell-tale silhoutte of the pinniped.  Some sharks, like the lemon shark (Negaprion brevirostris), have an interesting eye, where the sensitivity of the retina changes from light of one particular wavelength during day time to one of a different wavelength during night time.  This Purkinje-shift allows the animals to see optimally during day and night.  Now, many animals (or humans) in distress show a particular behavior.  Sometimes, a flight response is what is initiated when faced with a predator.  This behavior can signal the shark that the fleeing animal (or human) is afraid and therefore not a danger but rather a potential prey.  Consequently, fear in humans that cause a flight response may cause sharks to respond accordingly.  This may also be misunderstood as "smelling fear."  This, by the way, is the same kind of behavior a cougar, dog, or bear will dislay.\n\nThat said, there is always the possibility that during fear a human may release certain chemical compounds that the shark can smell.  But I doubt that this is something really significant in a real-life encounter.\n\n

From what science has been able to tell us, what we humans often refer to as "love" is, in fact, comprised of a number of different elements.\n\nPheromones, one of the basic components of smell, are picked up by receptors in the nose and converted to electrical impulses which tell areas of the brain that "here is someone to whom I could be attracted." "The evidence has now become quite strong that humans produce and detect pheromones," agreed Edward W. Johnson of Idaho State University in Pocatello. However, we should note that other researchers say more study is needed to find out if they are as powerful in humans as they are in other species.\n\nHumans, particularly males, are visually oriented, and sights that please us cause what is known as "pupillary dilation" (your pupils dilate when you see something you like).\n\n\n\nThe parasympathetic branch of the autonomic nervous system which mediates sexual arousal, induces such responses as pupillary dilation. When two people look at each other at the same moment, and both sets of pupils dilate, the result is what some people refer to as "love at first sight." We're reacting to the reaction of the other person, as well as to our own reaction to them.\n\nHumans, particularly females, react strongly to the sense of touch. The outer covering of skin is our body's largest "part." Skin makes up about 15% of the body's weight, and occupies some 21 square feet of surface area. Being touched by someone lowers blood pressure, releases endorphins (the brain's equivalent of opium), and causes many other strongly positive reactions. One report of touch deprived women revealed that only a tiny percent had ever had an orgasm.\n\nTaken together, all of these responses lead to sexual attraction, which affects our emotions, which many people translate as "love."\n\nYet, humans, besides being rather sophisticated members of the animal kingdom, are also rational and rationalizing beings. True, at times our emotions can completely eliminate rational thought, but most people can, with a bit of practice, overrule their emotions and make rational decisions.\n\nEveryone who has been married, or has been in a long-term relationship, has had moments when they were so angry at the other that they began to question whether they truly "loved" the other person anymore. Where were all those feelings they had when the relationship was young? What happened to that pit of the stomach, semi-dizzy, giddy euphoria?\n\nIt's at these points when we need to come to the realization that "feelings" are great, but the real test of love is when the pressure's on and everything seems to be going to hell in a hand basket. This is when we need to remember that love is a decision even more than it is a set of feelings. Sometimes we need to call upon our rational natures, overrule our feelings, and decide to love the other.\n\nIn a classic "which came first" question, most people would protest that "love should come first," then the mind will follow. What people mean by this is that feelings of being "in love" should come before we decide that we're in love with another person, a kind of "engage feelings before putting mind in gear." Unfortunately this approach doesn't have a very good track record. When we allow our feelings to dictate our reactions to other people, we wind up on an emotional roller coaster, falling in and out of "love" with alarming regularity.\n\n\n\nthis was an excerpt from paradigmassociates.org

The two answers that you see most often are nerve cell and ovum.\nBoth are correct.\n1. the nerve cells that make up sensory nerves have their cell bodies in the dorsal root ganglion located in the back and the have extensions (dendrites) that reach to the area sensed (all the way to the toes. (many millimeters long but very, very thin).\n2. The cell body of the ovum is the round and had the largest volume of any cell.

From the standpoint of memories existing in the cells of the body rather than in the brain, there have been reported cases of recipients of donated organs developing interests and tastes that correspond to those of the donor.  There have also been a few reported cases of memories of the donor surfacing.\n\nIt has been suggested that memories are stored in more than just the brain.  The nervous system runs throughout the body and it is connected to the brain.  Neuropeptides, chemical signals used by neurons to communicate information, have been found in all types of cells in the body and could be an indicator that some of the brain's functions may be distributed throughout the body.\n\nA paper published by the University of North Carolina lists several cases of memory transfer in donor recipients (see the source link below).

Your skin is your largest organ. It covers your entire body and has a surface area of around 2 square metres. Its thickness varies from 0.5mm on your eyelids to 4mm or more on the palms of your hands and the soles of your feet. In total, it accounts for around 16 percent of your body weight.

(m)\n\nSeventy to seventy-five percent of what we perceive as taste actually comes from our sense of smell. Taste buds allow us to perceive only bitter, salty, sweet, and sour flavors. It's the odor molecules from food that give us most of our taste sensation. \n\nWhen you put food in your mouth, odor molecules from that food travel through the passage between your nose and mouth to olfactory receptor cells at the top of your nasal cavity, just beneath the brain and behind the bridge of the nose. If mucus in your nasal passages becomes too thick, air and odor molecules can't reach your olfactory receptor cells. Thus, your brain receives no signal identifying the odor, and everything you eat tastes much the same. You can feel the texture and temperature of the food, but no messengers can tell your brain, "This cool, milky substance is chocolate ice cream." The odor molecules remain trapped in your mouth. The pathway has been blocked off to those powerful perceivers of smell--the olfactory bulbs. \n\nOf all our senses, smell is our most primal. Animals need the sense of smell to survive. Although a blind rat might survive, a rat without its sense of smell can't mate or find food. For humans, the sense of smell communicates many of the pleasures in life--the aroma of a pot roast in the oven, fresh-cut hay, a rose garden. Smells can also signal danger, fear, or dread. \n\nAlthough our sense of smell is our most primal, it is also very complex. To identify the smell of a rose, the brain analyzes over 300 odor molecules. The average person can discriminate between 4,000 to 10,000 different odor molecules. Much is unknown about exactly how we detect and discriminate between various odors. But researchers have discovered that an odor can only be detected in liquid form. We breathe in airborne molecules that travel to and combine with receptors in nasal cells. The cilia, hairlike receptors that extend from cells inside the nose, are covered with a thin, clear mucus that dissolves odor molecules not already in vapor form. When the mucus becomes too thick, it can no longer dissolve the molecules. \n\nAnimals depend on odors secreted from their bodies to communicate. For humans, odors communicate a variety of messages, depending on the odor and the person receiving it. The aroma of a baking apple pie sends one message when someone is hungry and quite another when that person has just finished a six-course meal!
