Differences
100
This nerve is important in the special senses of balance and hearing.
What is VIII, vestibulocochlear.
100
Cranial nerve I exits here.
What is foramina of the cribiform plate
100
This nerve is motor to lateral rectus and retractor bulbi muscles of the eyeball. It exits from the orbital fissure.
What is VI, abducent
100
This nerve gives motor innervation to tongue muscles.
What is they hypoglossal nerve
100
In this species the ventral buccal and dorsal buccal branches of the facial nerve are separated by the greatest distance. (The ventral branch is quite ventral.)
What is the dog
200
This nerve exits the optic canal.
What is II, optic
200
The maxillary branch of the trigeminal leaves through this foramen.
What is the round foramen? In ruminants it would be the orbitorotundum.
200
This nerve is sensory to the CAUDAL 1/3 of the tongue as well as providing the special sense of taste to the same region.
What is IX, glossophyrangeal
200
This branch of the facial nerve is distributed to the rostral 2/3 of the tongue. (Also carries taste fibers from the fungiform papille and GVE (parasympathetic) fibers to tongue glands)
What is the chordae tympani nerve *Side note: it grossly joins with the lingual nerve* SO THIS MAY NOT BE ON THIS EXAM...
200
In this species the dorsal and ventral buccal branches of the facial nerve are quite close to each other. (The parotid duct is very ventral, especially to these nerve branches.)
What is the horse
300
This nerve exits the skull at the stylomastoid foramen.
What is VII, facial
300
The mandibular branch of the trigeminal nerve exits here.
What is the oval foramen
300
This is the name of cranial nerve XI. Hint: it leaves through the tympano-occipital fissure and has a small contribution to the phyrangeal plexus and is motor to certain neck muscles.
What is spinal accessory
300
This nerve supplies taste fibers from the vallate and folliate papillae, parasympathetic fibers to lingual glands, and general sensation fibers to the caudal 1/3 of the tongue.
What is the glossophyrangeal nerve
300
In the horse we use the elevator of the upper lip (levator labii superioris) as a land mark to block this nerve.
What is the dorsal buccal nerve
400
This is the nerve that is motor to tongue muscles and exits the skull through foramen of the same name.
What is hypoglossal, XII
400
Cranial nerve X is one of three nerves that exit through this fissure.
What is the tympano-occipital fissyre
400
This branch of V is sensory to frontal and eye region, exiting via the orbital fissure.
What is the opthalmic branch
400
This branch of the mandibular nerve (branch of the trigeminal nerve) supplies GSA fibers to the rostral 2/3 of the tongue mucosa. These carry exteroceptive impulses.
What is the lingual nerve
400
In this species the dorsal and ventral buccal branches of the facial nerve are not close together, but the parotid duct is relatively just dorsal to the ventral buccal rather than more in between the buccal branches.
What is any ruminant And sorry the "answer" is so disgusting. But it's not too far off from what we might get on the written exam...
500
This nerve is motor to certain extrinsic eyeball muscles and parasympathetic to pupil constrictor muscle.
What is III, oculomotor
500
Nerve IV leaves via this fissure.
What is the orbital fissure
500
Name 2 of the 3 nerves that exit the skull from the tympano-occipital fissure.
What are IX/glossophyrangeal, X/vagus, and XI/spinal accessory
500
Most of the muscles of the tongue are innervated by this nerve.
What is the hypoglossal nerve/XII
500
This branch of the facial nerve is the MOST ventral of the 3 branches of the facial nerve in all species. (So this isn't really a species specific thing but it goes along with the other nerves in this category.)
What is the auriculopalpebral branch of the facial nerve
