Neuron and Nervous System

Psychology : Biological Basis of Behavior : Section trey The neuron and the nauseous corpse ·central nervous, which consists of the brain and the spinal anesthesia cord, is one division · marginal nervous system, which is divided into the somatic nervous system (the purposeless muscles) and the involuntary nervous system (the gland and internal organs) · autonomic nervous system is boost broken down into the merciful nervous system ( overreachs the be ready for challenge) and parasympathetic nervous system (brings the carcass stomach to homeostasis or normal situation). · neuron or warmheartedness cellphone is the basic unit of the nervous system. Neurons make up the intercourse network throughout the body. They deem messages all over the body. The neuron consists of three basic split that enable it to communicate with an some other(prenominal)(a) neurons. The first relegate is the dendrite, a tree-like process, which carries the teach ing to the cell body from other neurons. The second part is the cell body which contains a nucleus and is the part that volition decide if the neuron trace up stakes fire or non and it also directs the building of the neurotransmitters. The third part is the axon and its suppose is to carry information to other neurons. Some neurons are cover with a greasy sheath, called myelin and it allows the message to travel faster. Neurons are not attached and have a space surrounded by them, called a synapse. The message travels down the neuron from dendrite to cell body to axon over the synapse to other dendrites etc. Since an axon has numerous terminals at its end an axon can connect with many another(prenominal) other neuron dendrites. The neural connections that are present correlate with intelligence. Neurotransmitters are stored in the axon terminals in structures called synaptic vesicles. These chemicals will tide over the synapse gap to carry the message on. Neurons communicate with separately o! ther by chemical and electrical messages. When a nerve is stimulated, an action potential (a change in the electrical...If you want to get a full essay, order it on our website: OrderCustomPaper.com
