Flashcards in Somatic Afferent (SA) Pathways of the Oculomotor, Trochlear, and Abducent Nerves Deck (9)
What do somatic afferent (SA) pathways monitor?
- light touch
Does the apparent origin of cranial nerves III, IV, and VI contain SA fibers?
What part of the III, IV, or VI cranial nerve contains SA fibers?
only the distal part of the nerve
Peripheral sensory processes conveyed in the III, IV, or VI cranial nerve will communicate with which cranial nerve branch?
ophthalmic division of trigeminal
Peripheral sensory processes conveyed in the III, IV, or VI cranial nerve travel to pseudounipolar sensory neuron cell bodies located in which ganglion?
Gasserian ganglion, semilunar ganglion, or trigeminal ganglion
Central sensory processes from the Gasserian ganglion are conveyed to the pons in what structure?
the sensory root of the trigeminal nerve
Typically, primary afferent neurons of the III, IV, or VI cranial nerve located in the semilunar ganglion will synapse in what nucleus?
spinal trigeminal nucleus
Recently, peripheral sensory processes conveyed in the III, IV, or VI cranial nerve have been shown to originate from primary afferent neurons in which location?
mesencephalic nucleus of the trigeminal nerve
