jenifer reyes period 2
action potential
spinal nerves
gray matter
white matter
bundles of myenlinated nerve fibers
major functions of of NS
movement internal process of physiology
sensory functions and receptors
detect internal and external changes
info travels from receptors to sensory neurons
transport to CNS-
integrative funtions-
coordination of sensory info in CNS
processing information into is basis for decision making
motor fun
effectors- muscle glands respond respond to disicion made in cns
nerve impusles conducted along motor neurons
main functions of the brain
cerebrum
bigger part of the brain
cerebellum
smaller part of the brain
peritetal lobe
thalamus
hypothalamus
frontal lobe
the front portion
occtiputical lobe
mid brain
pons
cerebellum
medulla
neurotransmitter
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
cranial nerves
most are mixed (sensory and motor neuron fibers)
others are primarily motor
some are only sensory
connective tissue coverings
endoneurium
coverings around individual never fibers
axons
epineurium
outrer coverings of nerve
perininium-
covering around fscicles of nerve fibers
bundles
reflex arc-
motor effrerent neuron
glands and mucles=receptors
central nervous system
sensory or afferent neuron
receptors
tissues
neurogila
cells that support neurons
doesnt generate nerve impulses
cns- microgila
small cells
parts of function and spinal cord
cuada equina
the 31 segments that are connected to the spinal cord
cervical enlargement
thickened area at the top and provides nerves to the upper limbs
lumbar enlargement
the regoin that is thickened near the bottom and riseto the nerves for the lower rimbs
dorsal root gangila
cell bodies of sensory neurons that enter in the spinal cord
central canal
middle of gray matter contains cerebrospinal fluid
posterior and anterior horns
lateral horn in between
upper and lower wings of gray matter
