nerves Flashcards
exam 1
meninges has __ layers
3
it is the boundary between the CNS and PNS
meninges
groups of nerve cell bodies that live outside
ganglia
sensory neurons
unipolars
interneurons
bipolar
motor neruons
multipolars
information from sensory to the CNS
afferent
impulses away from the CNS
efferent
SAME DAVE
sensory afferent
motor efferent
dorsal afferent
ventral efferent
unipolar sensory neurons cell bodies are found in the
dorsal root ganglion
multipolar motor neurons cell bodies are found in the
ventral root
autonomic innervate
smooth muscles
autonomic neurons live in
intermediolateral cell solumn
the difference between somatic and autonomic?
Somatic is only one chain and autonomic is 2-chains
ventral primary rami innervates the
intercostal nerve
Voluntary
monitor and regulate skeletal muscle and skin sensation
somatic
Somatic Sensory Fibers; dorsal root ganglion
General Somatic Afferent
Somatic Motor Fibers; spinal cord ventral horn
General Somatic Efferent
Involuntary
monitor and control visceral function
autonomic
the spinal nerve exits below the vertebra
below T1
Each spinal nerves will exit the vertebral canal through the
intervertebral foramen
where is the spinal fluid?
subarachnoid space
spinal cord only extends down to the
L1/L2
dural sac extends down to the
S2
