The nervous system is divided into the central nervous system (which is the brain and spinal cord), and the peripheral nervous system. \n\nThe peripheral nervous system is everything outside the central nervous system (brain and spinal cord). This peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system. \n\nThe somatic nervous system controls your voluntary behavior (skeletal muscle), and the autonomic nervous system controls the internal organs (involuntary behavior such as smooth muscle contractions). The autonomic nervous system is further divided into the sympathetic division and the parasympathetic division. The actions of both of these divisions is antagonistic to each other, but they work together.\n\nLet's say you are in the woods and you see a bear coming after you. The sympathetic system increases your heart rate, epinephrine is secreted, constricts blood vessels to organs such as that are involved in the digestive process so that more blood goes to your muscles, dilates your pupils, widen bronchial passages, etc. The parasympathetic system does the opposite. If you are laying down on a couch after a meal, your parasympathetic system is in charge. Your heart rate will decrease (no point in increasing it since there is no major physical activity), more blood going to your digestive organs, pupils are not as dilated, etc. The parasympathetic system is the "rest and digest" system.

Functional classification There are three functional classes of neurons: afferent neurons, efferent neurons, and interneurons.\n\nAfferent neurons convey information from tissues and organs into the central nervous system. \nEfferent neurons transmit signals from the central nervous system to the effector cells. \nInterneurons connect neurons within specific regions of the central nervous system.

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.

The adrenal gland in the endocrine system actually works in co-ordination with the autonomic nervous system of the peripheral nervous system.

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).

The central nervous system is made up of the brain and the spinal cord. \nThe peripheral nervous systems is structurally made up of cranial nerves, spinal nerves, ganglia and sensory receptors( eye, ears etc.) Functionally, the PNS is divided into somatic and autonomic. The somatic system is under our control and involves skeletal muscle contraction. The autonomic system is further subdivided into parasympathetic and sympathetic. The  parasympathetic is the system responsible for everyday function such as digestion etc.; it is known as the rest or repose system. The sympathetic acts only when in a stress situation and is related to survival; it is known as the fight or flight system.

Neurons are a major class of cells (parenchyma) in the nervous system whose main role is to process and transmit information. In vertebrate animals, neurons are found in the brain, the spinal cord and in the nerves and ganglia of the peripheral nervous system.\n\nNeurons are typically composed of a cell body, a dendritic tree and an axon. In the classic view of vertebrate neuron function, the cell body and dendritic tree receive electrical signals from other neurons while the axon transmits electrical output signals. For invertebrate neurons, the information flow is less well defined.\nYOUR QUESTION:\nAre they the motor end plates of the effector neurones?\nYES:\nNeurons are able to generate and propagate electrical impulses because they have excitable membranes. Neurons make connections with other neurons and transmit information to them via synaptic transmission. Different types of neurons have different shapes(Like Plates), possess specific electrical properties adopted for their function and use different neurotransmitters.

ERP systems are commonly referred to in the industry as the "information backbone" of a company. Thinking literally about that reference makes sense. Just like the backbone in the human body, the ERP system serves as the company’s central nervous system. All business functions emanate from the ERP information backbone: financials, supply chain management, customer relationship management, and human resources. And, ERP systems keep developing to handle more of these functions.

The plug on the end that goes into the wall!\n\nThe real answer is that every component is as important as the other.\nJust go in and snip a wire or a resistor for fun.\n\nIf I leave my brain at home I can't function, can I? Is the brain the most important organ in the human body? What if I leave my liver at home.  Soon I'm dead. How about I leave my stomach at home and go to a Chinese buffet. Gads what a mess I'd be in! So is the brain more important than the liver or stomach. Me thinks not. For any complicated organism or device to work it needs all it parts so each part is as important as the other.

Central Nervous System (CNS) includes the brain the spinal cord. Then the Peripheral Nervous System (PNS). The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system. \nThe somatic nervous system is responsible for coordinating the body's movements, and also for receiving external stimuli. It is the system that regulates activities that are under conscious control.\nThe autonomic nervous system is then split into the sympathetic division, parasympathetic division, and enteric division.\n\nHope i have helped you.....\nby the way.. your heart is part of your nervous system.... you can read it in the site below....
