Structure and functions of the nervous system
Muscle contraction is initiated by the nervous system which together with the endocrine system controls the human organism. They are responsible for the steadiness of the inner environment and coordination of all the bodily functions. The nerve cell, a neuron, is the basic unit of the nervous system . Cells attending to muscles are called motoneurons. A neuron is composed of the body and projections. The shorter ones are called dendrites, the long one is axon. Through the dendrite the neuron is able to obtain information from other neurons. The axon then passes the processed information to other cells (e.g. muscle cells). The information is further spread along the neuron through changes in the voltage in the cell membrane, the so called action potential. The transfer of information between individual nerve cells is then secured by chemical agents. Once the action potential has reached the end of an axon, the mediator is released.
