The limbic system is in the right hemisphere of the brain. The limbic system controls sensory, arousal and generating emotions. The hippocampus is responsible for memory. A good anatomy and physiology book is one by Martini. Hope this helps.

it has so many functions.. all concerning autonomic actions (involuntary actions) - \nthe most important are: \n1- control of cardiac activity (it has 2 centers: cardiac accelerating and inhibitory centers)\n2- control of respiration (via dorsal and ventral motor neurones)\n3- regulation of heart rate and respiratory rate via central chemoreceptors\n4- regulation of arterial blood pressure by controlling the diameter of arterioles via vaso-motor center\n5- control of vital actions as swallowing ...etc

As someone already said, the cerebellum helps regulate coordination.  But there is also a region the the cortex, called the motor cortex, that sends signals to your muscles.  It's about at the top and middle of your head, and runs from the center line towards either side (the left side controls the right side of your body, and the right side controls the left).  It's about a finger or two wide.  It contains a complete "map" of your body, in that a nerve cell (neuron) at one location of the map, when stimulated electrically, sends a signal to one particular muscle; a neighboring neuron maps to a neighboring muscle.  It's not one-to-one mapping, but continuous smooth changes, with some sudden breaks in the map.  And there are more nerve cells mapping to your lips and fingers (and the like) than to other areas, so you have much finer control over fingers, lips and the like than you do over other regions.\n\nThere's a similar map for sensory input, close by in the cortex but not directly connected.  There's also a premotor cortex, toward the front of your head from the motor cortex, that is responsible for the planning of motions.  The premotor cortex then sends the appropriate nerve signals to the motor cortex, that directly controls the muscles.

1. Nerve anatomy: nerves are axons of a neuron, enclosed by myelin, and are part of the peripheral nervous system. Afferent nerves carry sensory information from the body to the dorsak root ganglia of the spinal cord and then to the brain (although cranial nerves go directly to the brain). Efferent nerves carry motor information from the brain to the body (muscles) to contract or relax. \n\n2. Reflex architecture: reflex arc. Sensory info (i.e. pressure) activates specialized sense receptors-->sends afferent signal to dorsal root ganglia of spinal cord-->sends info to interneuron-->sends info to ventral root-->sends efferent info to muscle-->muscle contracts (or relaxes, muscles work in pairs).\n\n3. Embryo forebrain-->telencephalon (cerebral cortex, basal ganglia, and limbic system). Midbrain-->Mesencephalon (thalamus, hypothalamus). Hindbrain-->metencephalon (cerebellum and pons) and myelencephalon (medulla oblongata).\n\n4. Functions of what?\n\n5. Hearing: consists of outer, middle, and inner ear. Outer ear is ear canal, middle ear is the ear drum and 3 smallest bones in body (hammer, anvil and stirrup), inner ear is the cochlea. Sound waves travel through the canal, cause the ear drum to vibrate, which moves the 3 bones, which causes the fluid in the cochlea to move, which activates the hair cells (receptors) that send infor to the auditory cortex in the brain.\nVision: from the outer eye to inner eye, you have cornea, iris, pupil, lens, vitreous humor, and the retina (which has the receptors). Within the retina, you have photoreceptors, bipolar cells, ganglion cells, and amacrine cells. Photoreceptors are rods (light) and cones (color). From the ganglion cells, information gets sent to the primary visual cortex in the brain.\n\n6. The spinal cord is long tube protected by vertebral column. It has white matter (axons or nerves from above definition) on the outside and gray matter (cell bodies) on the inside. The gray matter kind of looks like a butterfly in the spinal cord.\n\n7. Cerebellum: coordinated movement\nThalamus: sensory relay station\nCerebrum: divided into 4 sensory lobes, performs several higher functions such as language, emotion, and memory.\nHypothalamus: controls autonomic nervous system and endocrine systems (4 F's: fighting, feeding, fleeing, and mating...)\nMedulla: controls vital functions (cardiovascular, respiration, and skeletal muscle tone).

Erection is a physiological process controlled by various neuroendocrinal and autonomic body function.It is controlled by parasympathetic nervous system which lead to vasodilation in vessels of corpora cavernosa that results in blood pooling in penis and hence produce erection.It is misconception that it occurs only during sexual arousal.its important for sexual functioning hence limbic system of brain do causes cascade of Nero endocrine changes to cause erection.limbic system may be activated by visual,auditory,touch sensation,smell or even just thought related to sexual feeling.but it can also occur without limbic system involvement(without sexual feeling) as it may be purely neural response.best example i can give is during REM sleep(dreamy sleep) or seizure activity.this is because of excessive autonomic neural discharges.special mention about pathological erection which is difficult to reversible is essential. it is usually due to vessels obstruction best example for it is sickle cell anaemia.

psychoendoneuroimmunology (PENI), provides both the concepts and the mechanisms for studying and explaining mind-body relationships. The brain is the body's first line of defense against illness, and the mind is the functioning of the brain. PENI incorporates ideas, belief systems, hopes, and desires as well as biochemistry, physiology, and anatomy. As we change our thoughts, we are changing our brain and thus our biology and our body. Belief systems set a baseline for the brain upon which other variables will act and have their effects.

Functionalism is the study of why thoughts, feelings and behavior occur, and how they are adaptive. The goal of functionalists is to understand how the mind helps a person function and adapt to the world around them.

Depends on what type of science you are limited too.  Studying the sensory systems, sensory integration, types of sensory input that people are not aware of or how it is processed.  The brain has so many interesting areas to study the ideas are endless.  For example, hit the internet and type in words like: limbic system, triune brain, proprioception, dyspraxia, PET scans, cranial nerves (especially looking at the interaction between movement and sound), bilateral integration just some beginning thoughts.

It has its basis in brain structure.  I saw it on Discovery Channel a while back.

The endocrine system  regulates mood, growth and development, tissue function, metabolism, and sexual function and reproductive processes.It is in charge of body processes that occur slowly. The most imporant parts of the endocrine system are hormones and glands. Hormones transfer information and instructions from one set of cells to another and only affect certain cells. Glands produce and secrete chemicals. A gland selects and removes materials from the blood, processes them, and secretes the finished chemical product for use somewhere in the body.

The primary function of the male reproductive system is reproduction, which includes the production of spermatozoa, the transportation of spermatozoa from the testes out of the male body, the secretion by glands, and the placement of spermatozoa in the female reproductive tract. Spermatozoa are produced in the testes then transported from the testes by a series of ducts which become gradually larger and connect with the urethra of the penis.  Various accessory glands in the male system secrete materials which together with the spermatozoa constitutes the semen. A secondary function of the male reproductive system is the production of the male hormones which are responsible for the secondary sex characteristics of the male animal.\n\nhttp://www.cvm.okstate.edu/instruction/mm_curr/histology/MR/himrp1.htm\n\nThe male reproductive system, like that of the female, consists of those organs whose function is to produce a new individual, i.e., to accomplish reproduction. This system consists of a pair of testes and a network of excretory ducts (epididymis, ductus deferens (vas deferens), and ejaculatory ducts), seminal vesicles, the \nprostate, the bulbourethral glands, and the penis. \n\nhttp://training.seer.cancer.gov/module_anatomy/unit12_2_repdt_male.html\n\nThe organs of the male reproductive system are specialized for the following functions:\n\nTo produce, maintain and transport sperm (the male reproductive cells) and protective fluid (semen) \nTo discharge sperm within the female reproductive tract \nTo produce and secrete male sex hormones \n\n\nhttp://www.cchs.net/health/health-info/docs/2300/2376.asp?index=9117

Your brain is divided into six major divisions:  the cerebrum, the diencephalon (where the hypothalamus is located), the mid brain, the cerebellum, the pons and the medulla oblongata.  \n\nThe hypothalamus is the center for homeostasis and controls things like hunger, thirst, maintaining body temperature and the control of some reproductive system functions.\n\nThe medulla oblongata is where the spinal cord transitions into the brain.  It is part of the brain stem.  It's job is the control of non-voluntary functions and it also brings sensory information into the brain and helps the cerebral cortex relay information to the spinal cord.\n\nHope this helps...

Parts of our brain are used for senses. Touch, smell, taste, etc. They map which parts of the brain relate to which, and it makes psychologists and brain surgeons very excited. It's also how foreplay/non-conventional sex can be explained. See, our lips have one of the greatest surface areas on the physical sense brain map, meaning our lips are really sensitive. So are our, well, erogenous zones, genitals and such. So, we put the two sensitive organs together, and it makes everyone happy. Same explination for kissing.

The prefrontal cortex is responsible for many processes unique to higher vertebrate mammals.  I believe this would certainly have to be at least part of it.

Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the "conducting" cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell. The word "neuroglia" means "nerve glue." These cells are nonconductive and provide a support system for the neurons. They are a special type of "connective tissue" for the nervous system.\nNeurons\n\nNeurons, or nerve cells, carry out the functions of the nervous system by conducting nerve impulses. They are highly specialized and amitotic. This means that if a neuron is destroyed, it cannot be replaced because neurons do not go through mitosis.

Tasting, smelling, seeing, hearing, thinking, dreaming, breathing, heart beating, moving, running, sleeping, laughing, singing, remembering, feeling pain or pleasure, painting, writing...you couldn't do any of these things without your central nervous system! \n\nWhat is the nervous system? \nMade up of your brain, your spinal cord, and an enormous network of nerves that thread throughout your body, it's the control center for your entire body. Your brain uses information it receives from your nerves to coordinate all of your actions and reactions. Without it, you couldn't exist! \n\nWhat are nerves? \nThey're the thin threads of nerve cells, called neurons that run throughout your body. Bundled together, they carry messages back and forth just the way that telephone wires do. Sensory nerves send messages to the brain and generally connect to the brain through the spinal cord inside your backbone. Motor nerves carry messages back from the brain to all the muscles and glands in your body. \n\nSo how do they they pass along messages? \nThrough the marvels of chemistry and a kind of electricity! Neurons are thin. Some are very small, and some can be three feet long! All are shaped somewhat like flat stars which have, to varying degrees, been pulled at each end so that they have long fingers. The fingers of one neuron almost reach to the next neuron. \n\nWhen a neuron is stimulated -- by heat, cold, touch, sound vibrations or some other message -- it begins to actually generate a tiny electrical pulse. This electricity and chemical change travels the full length of the neuron. But when it gets to the end of finger-like points at the end of the neuron, it needs help getting across to the next extended finger. That's where chemicals come in. The electrical pulse in the cells triggers the release of chemicals that carry the pulse to the next cell. And so on and so on and so on. \n\nSource(s):\n\nsearch engine: ask.com\nkey words: The Nervous System\n(This is pretty broad in nature, is there a specific question related to an answer you need that I can help you with?\nohhhhhh...nurse?????
