action potential

spinal nerves

major functions of of NS

main functions of the brain

movement internal process of physiology

sensory functions and receptors

integrative funtions-

coordination of sensory info in CNS

processing information into is basis for decision making

detect internal and external changes

info travels from receptors to sensory neurons

transport to CNS-

neurotransmitter

cranial nerves

connective tissue coverings

reflex arc-

tissues

cerebrum

cerebellum

peritetal lobe

thalamus

hypothalamus

frontal lobe

occtiputical lobe

motor fun

effectors- muscle glands respond respond to disicion made in cns

nerve impusles conducted along motor neurons

realeased in response to a nerve impulse

more than 100 neutransmitters

some neurons produce more that one type of transmitter others produce 2 or more

actions depend on type of receptors in specific synapse

including acetylcholine amino acid neuropeptides

diffuse acroos sthe cleft and bind to receptors on the membrane of the postanymatic neuron

communication accomplished by a chemical

stores and released from synaptic

endoneurium

epineurium

perininium-

coverings around individual never fibers

outrer coverings of nerve

covering around fscicles of nerve fibers

axons

bundles

most are mixed (sensory and motor neuron fibers)

others are primarily motor

some are only sensory

mid brain

pons

gray matter

white matter

cerebellum

medulla

parts of function and spinal cord

cuada equina

cervical enlargement

lumbar enlargement

dorsal root gangila

central canal

posterior and anterior horns

middle of gray matter contains cerebrospinal fluid

the regoin that is thickened near the bottom and riseto the nerves for the lower rimbs

thickened area at the top and provides nerves to the upper limbs

the 31 segments that are connected to the spinal cord

lateral horn in between

upper and lower wings of gray matter

cell bodies of sensory neurons that enter in the spinal cord

bundles of myenlinated nerve fibers

bigger part of the brain

smaller part of the brain

the front portion

motor effrerent neuron

glands and mucles=receptors

central nervous system

sensory or afferent neuron

receptors

neurogila

cns- microgila

small cells

cells that support neurons

doesnt generate nerve impulses
