CADE EXAM 5: INTRODUCTION TO CRANIAL NERVE

Typical spinal nerves contain which nerve fibers
Somatic motor
somatic sensory
postganglionic sympathetic fibers




Instead of having dorsal, ventral or lateral horns like the spinal cord, the brainstem
consists of _____________________________ which correspond to the different fiber
types within each cranial nerves (______________________)
Cranial nerve nuclei (containing motor, sensory, parasympathetic fibers)




Cranial nerve motor nuclei serve as the origin for
Somatic motor fibers.




Cranial nerve motor nuclei innervate
Skeletal muscles of the face and neck




Cranial nerve motor nuclei is equivalent to the

,Ventral horn of the spinal cord




Cranial nerve sensory ganglia are equivalent to the
Spinal ganglia (dorsal root ganglia)




Cranial nerve sensory ganglia have a ______________________ that is associated
with a receptor
Peripheral process




Cranial nerve sensory ganglia have a ______________________ that terminates in a
______________________________________________________________
Central process

cranial nerve sensory nucleus




The cranial nerve sensory nucleus is equivalent to the
Dorsal horn of the spinal cord

, ______________________ also have parasympathetic nuclei
Cn iii, vii, ix, x




Parasympathetic nuclei are equivalent to the
Lateral horn of the gray matter of the spinal cord s2-4




The preganglionic parasympathetic fibers must synapse in a
_______________________________________ in the head (except the
_________________)
Parasympathetic ganglion

except the vagus nerve




These cranial parasympathetic ganglia are the ______________ ganglia
Cops

ciliary (iii)
otic (ix)
pterygopalatine (vii)
submandibular (vii)
