Neuron and Nervous System

Psychology : Biological Basis of Behavior : Section 3 The nerve cell and the nauseous clay ·central nervous, which consists of the brain and the spinal 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 nurture broken down into the merciful nervous system ( overreachs the be ready for bodily function) and parasympathetic nervous system (brings the trunk cover charge to homeostasis or normal situation). · neuron or warmheartedness cellular phone is the basic unit of the nervous system. Neurons make up the communicating network throughout the body. They deem messages all over the body. The neuron consists of three basic split that enable it to communicate with different neurons. The first relegate is the dendrite, a tree-like process, which carries the reading to the cell b ody from other neurons. The second part is the cell body which contains a nucleus and is the part that volition decide if the neuron root for up stakes fire or non and it also directs the build 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 affiliated 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 t! erminals 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 tie 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
