CRANIAL NERVES
primarily motor, responsible for the raising of eyelids, and moving eye
OCULOMOTOR (III)
Outer most layer of the cerebrum thin layer of gray matter and contains almost 75% of neuron cell bodies
CEREBRAL CORTEX
conduct motor impulses with the suffix ending of -spino
DESCENDING TRACTS
supply motor impulses to adductors of thighs; found in lumbosacral plexus
OBTURATOR NERVE
An excitatory neurotransmitter causes this type of membrane potential change
DEPOLARIZATION
Sensory only, associated with vision
this part of the brain is responsible for translating sensory information into proper emotional response
INSULA
These make up this area; lateral funiculus; anterior funicular; posterior funiculus
WHITE MATTER
supplies muscles of anterior arms and skin of forearms
MUSCULOCUTANEOUS NERVE
Na+enters the axon depolarizes membrane of postsynaptic neuron
ECITATORY POSTSYNAPTIC POTENTIAL
EPSP
mixed nerve, largest pair of cranial nerves with 3 sensory branches
TRIGEMINAL
cerebrum, diencephalon, cerebellum, brainstem
MAJOR PORTIONS OF THE BRAIN
formed by descending roots of lumbar, sacral, and coccygeal nerves
CAUDA EQUINA
This nerve is affected when it is compressed causing back in lower back, gluteal region, things, calf, and feet
SCIATIC NERVE
voltage-gated sodium channels remain closed during this
RESTING POTENTIAL
Smallest pair of cranial nerves, motor nerve that move eyes
TROCHLEAR NERVE (IV)
this connects cerebral hemispheres
CORPUS CALLOSUM
contains cell bodies of sensory neurons
DORSAL ROOT GANGLION
VII
FACIAL NERVE
action potential of postsynaptic neuron becomes less likely
INHIBITORY POSTSYNAPTIC POTENTIAL
IPSP
Bipolar Neuron; passes through the cribriform bulbs associated with sense of smell, sensory nerve only
OLFACTORY NERVE (I)
Responsible for emotional behavior, judging consequences of behavior
FRONTAL LOBE
the patter of this area roughly resembles a butterfly with its wings spread
GRAY MATTER
arise from C3-C4-C5 nerves transmit motor impulses to the diaphragm
PHRENIC NERVE
rapid sequence of depolarization followed by repolarization, exhibits all-or-none properties
ACTION POTENTIAL
