Document Summary

Cpa 2: the nervous system, neurons, neurotransmitters (p. 42-54) Complete the following organizational chart with descriptions of the function of each part of the nervous system. Central nervous system- (cns) the brain and spinal cord, more than. 99% of all nerve cells are located here. Directs the manufacture of substances that the neuron needs for growth and maintenance. Treelike fibers projecting from a neuron; receive information and orient it toward the (cid:374)euro(cid:374)"s (cid:272)ell (cid:271)ody; (cid:373)ost (cid:374)er(cid:448)e (cid:272)ells ha(cid:448)e (cid:374)u(cid:373)erous de(cid:374)drites, (cid:449)hi(cid:272)h i(cid:374)(cid:272)rease their surface area, allowing each neuron to receive input from many neurons. The part of the neuron that carries info away from the cell body toward other cells; extremely thin but very long with many branches. Consists of a layer of cells containing fat; encases and insulates most axons; by insulating axon, they speed up the transmission of nerve impulses; without these axons are not very good conductors of electricity.
