do worms have a brain and can they feel?
491831
Most worms don't realy have a brain. They have nerve ganglia in their heads but they are too simple to be considered brains. The only worms that have what could be considered real brains are the acorn worms.\n\nCan they feel? Well they can sense, which is to say they can move towards food and away form some danger. But cabbages can do that as well. They can't feel in the sense that humans and other mammals can feel. They are not self aware and they can't feel pain, anxiety, joy and so forth

Yes....all beings have emotions, which they express humans do not always recognise.\n\nit is a relative recent discovery by the scientific fraternity, that all beings with cognative abilities have emotions. feeling of Love, pain, happiness, fear. This includes your clam.\n\nFear is the most prominent in all species including humans. This results in either attacking, submission, defence etc.

No.  Worms do not breath as we do.  They are essentially just one long dirt processing plant.  All gut.  If I remember my High School biology correctly, worms absorb oxygen through their skin, thus do not have breath or lungs.  \n\nPS:  You can cut a worm in half at the smooth section in the center, and it will crawl of and remain alive as two separate worms!!  Cool, huh?\n\nPSS: anojetak ... to funny!!

They do, but some animals have a higher tolerance than humans.  Think about it, how would you feel after you eat a rotten carcass or plants off the ground.

symptoms of lice: itchy scalp...specifically behind ears and back of neck, feeling like something crawling on scalp, finding things stuck to your hair that look like little eggs, finding brown bugs\n\nthis is to help you determine if it is lice or rule it out: HeadLice.org

Millions of people are infected by the parasites worms worldwide. Parasites can enter our bodies through food, water, mosquito bites, or through the nose and skin. More than 100 types of parasites worms can be living happily in human bodies. Some are big in size that can be seen by eyes, while the others are microscopic in size. Only about 5 percent of these varieties can be tested positively with only 20 percent accuracy. \n\nParasites worms find a perfectly living environment when the bowel becomes ineffective in the elimination of the waste products due to constipation. \n\nParasites may be categorized into four types: Protozoa, Trematoda, Cestoda, and Nematoda. Nematodes include common roundworm, hookworm, whipworm, pinworm, heart worm, etc.

Earthworms do lay eggs.

Hi, \n\n  Its possible. They live in your intestine and use the nutrition that you eat to live. They can cause the symptoms that you described. She did give you the right medicine to treat you. Worms are more of an occurrence that happen to small children that play outside in the dirt and put their hands in their mouth before washing them. I think you'll be fine.

That would be up to the dreamer.  If worms are found to be revolting, it could be a guilt or fear issue.  If they are not, it could mean something completely different.  I realize this isnt much help, but it is the dreamers subconscious creating the dream and it is up to that person to determine what it means.  Write it down and dissect it according to what each detail means to you.  Good Luck!

I think there is a difference between 'feelings' and 'senses.' I am not sure if they feel happy or sad feelings...but they do sense pain and they do panic.

WOW, wayyy too detailed of a question.... not gonna answer each part of this... "how it is possible?"  I mean, how broad is that? are you looking for actual hormone and neurotransmitter names and fuctions?  too broad..\n\nbut to answer... some fish, most plants are born XXY, platyhelminthes (roundworms)  and some cestodes, specific nematodes can change their sex... I believe the Ascaris Lumbricoides is my "favorite" sex change organism... it is a hermaphrodite and impregnates itself and lays eggs by itself.. without ever seeing another Ascaris.  (human parasite)

Ancient Behaviors Hard-Wired in Human Brain\n\nBy Robert Roy Britt\nLiveScience Senior Writer\n6 March 2005\n\nDon't blame your lame smile or lack of an intimidating frown on your upbringing, a new study suggests. Such behaviors may be hard-wired in your brain.\n\nScientists know many behaviors of lower organisms are innate. Ants instinctively follow other ants to a picnic basket. Birds operate largely on autopilot, dogs less so.\n\nIn people and monkeys, however, behavior is largely something learned, so researchers have assumed our hard-wiring is limited. If that's true, however, why do many reactions, such as aggression, play out the same among diverse populations around the world?\n\nScientists announced Tuesday they can elicit complex behaviors by stimulating specific areas in the brain of a small primate called the bush baby. Similar studies have been done on other primates.\n\n"We have now seen this feature in the brain of an Old World monkey and New World prosimian," said study leader Jon Kaas of Vanderbilt University. "The fact that it appears in the brains of two such divergent primates suggests that this form of organization evolved very early in the development of primates. That, in turn, suggests that it is characteristic of all primate brains, including the human brain."\n\nThe triggered behaviors include aggressive facial gestures, defensive arm movements, putting hand to mouth and other reaching and grasping movements -- all survival skills.\n\n"These results explain why certain behaviors – such as defensive and aggressive movements, smiling and grasping food – are so similar around the world," Kaas said. "It is because the instructions for these movements are built-in and not learned."\n\nThe results are detailed in the online edition of the Proceedings of the National Academy of Sciences.

I hate to suggest this, but could they be coming out of you?  Is it possible you've got worms?  Are you losing weight?  Wow, I want to ask no end of questions now, I guess you wouldn't know how you got them?

the worms are actually larvae -- they are pre-pubesent incects like flies.  the flies lay their eggs in food -- chances are you have eaten a billion fly eggs in food and never knew it.  anyway back to the story -- when the food gets the right mositure it signals the eggs hatch out larvae that live off the decomposing food  and they get big and fat and round.

Yes, they have hearts, to circulate their body fluids, and some may even be said to have 2 (or more?) hearts. So insects are good-hearted little animals. However, their circulation isn't as efficient as in larger animals which have a completely-closed system of arteries and veins (insects lack this).

the purpose of nerves is to transport pain and pleasure so i don't think organizims without them feel either as we know it , but there is not way to know,some plants react to stimuli and they do not have nerves so it is a great qiestion that there may be no answer to

they react to the situation but dont feel it like mammals do.ask a fisherman they say the fish cant feel the hook but they do react to it
