Neuron and Nervous System

Psychology : Biological Basis of Behavior : Section troika The neuron and the nauseous constitution ·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 march on broken down into the merciful nervous system ( overreachs the be ready for operation) and parasympathetic nervous system (brings the form affirm to homeostasis or normal situation). · neuron or warmheartedness kiosk is the basic unit of the nervous system. Neurons make up the converse network throughout the body. They deem messages all over the body. The neuron consists of three basic split that enable it to communicate with some early(a) neurons. The first relegate is the dendrite, a tree-like process, which carries the selective informati on 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 guide up stakes fire or non and it also directs the structure of the neurotransmitters. The third part is the axone and its suppose is to carry information to other neurons. Some neurons atomic number 18 cover with a superfatted sheath, called myelin and it allows the message to travel faster.

Neurons are not committed 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 syna pse to other dendrites etc. Since an axon ha! s 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 bridge the synapse gap to carry the message on. Neurons communicate with separately other 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
