Nervous System: Basic Structure and Function

sensory neurons-transmit info from the bodys sensory receptors to the CNS

axon terminals-what axons branch out into and end at enlarged tops called neurotransmitters

axon- single extension that sends more nerve impulses

Brain and Spinal Cord- control center for the Body

CNS-integrates incoming info. & determines appropriate responses

PNS- Peripheral nervous syste- composed of all sensory receptors and nerves that communicate w/ CNS

Sympathetic-"Fight or Flight"

parasympathetic-control rest & digest

Neurons- the structural functional units of the nervous system

Soma(cell body) - central region of the neuron

Glial Cells- act as neural assistantsby providing structural support (entourage)

Oligodentrocytes- cells that produce the Myelin sheath (CNS)

myelin sheath- wrapping around nerve fibers that insulate, protect, and support the neuron

nerve-bundle of axons

ganglion-mass of neural cell bodies
