Document Summary

Nervous system is composed of neurons, which produce and conduct electrochemical impulse, and supporting cells, which assist the functions of the neurons. Central nervous system= brain and spinal cord: seven major parts of the cns and three broad regions of the brain. Peripheral nervous system= cranial nerves arising from the brain and the spinal nerves arising from the spinal cord. Somatic motor neurons or autonomic motor neurons. Nuclei: cns supporting cells (oligodendrocytes, microglia and astrocytes) Ganglia/ glia: supporting cells of the pns (schwann cells and satellite cells/ ganglionic gliocytes) Axons turn into bundles form fibers: cns= tract and nerves= pns: nerve: bundle of axons located outside the cns, bundle of axons in the. Classification of neurons functional: morphological, neurotransmitter released. Supporting cells: gila predominant glia of vertebrates. Four distinct regions of a neuron: dendrites- (and soma) synaptic potentials and integration (receiving information, soma, axon- action potential conduction, nerve terminal- synaptic transmission (transmitting information)
