o Central Nervous system: Brain and Spinal cord
o Peripheral Nervous system: consists of sensory and motor neurons
§ Somatic Nervous system: controls skeletal muscles and is mostly integrated with CNS.
§ Autonomic Nervous system: stimulates smooth and cardiac muscle and also glands. Is not as connected to CNS.
o Cell body--enlarged part containing nucleus
o Axon--single, long extension that conducts impulses away from cell body
o Dendrites--many short extensions that receive stimuli, conducts toward the cell body
o Neuroglia—supporting cells that form a myelin sheath around the axon. Either called oligodendrocytes(CNS) or Schwann cells(PNS). Function: aids transmission of nerve impulse, supplies nutrients, carries away wastes
