A. In and Up

B. In and Down

C. Down and out

D. None of the above

Down and out

Which of the following presents as downward and outward gaze, a dilated pupil, and ptosis in the right eye?

A. Facial N. Palsy

B. Trigeminal N. Palsy

C. Right Occulomotor N. Palsy

D. Left Occulomotor N. Palsy

Right Occulomotor N. Palsy

A. V1

B. V2

C. V3

Which of the following branches of the Trigeminal N. conducts sensory impulses from the nasal mucosa, palate, gums, and cheek?

A. V1

B. V2

C. V3

Tic Doulureuc is a Trigeminal neuralgia that causes intense, pulsating pain lasting several minutes to hours. It is caused by which of the following?

A. Inflammation of motor components of trigeminal N.

B. Inflammation of sensory components of trigeminal N.

C. Inflammation of motor and sensory components of trigeminal N.

D. Inflammation of mandibular branch of trigeminal N.

E. Absense of trigeminal ganglia

Inflammation of sensory components of trigeminal N.

T/F: V1 gives off sensory fibers that come from the cornea, nose, forehead, and the anterior scalp

What are the 5 major motor branches of CN VII, that innervate the muscles of facial expression, posterior belly of digastric m, stylohyoid m, and stapedius?

Associated with Somatic (Brachial) Motor

Temporal

Zygomatic

Buccal

Mandibular

Cervical

Describe the trajectory of the facial N.'s Visceral (parasympathetic) motor to lacrimal gland?

1. Facial N. leaves the Superior Salvatory Nucleus 2. Greater Petrosal N arises from CN VII and joins the Deep Petrosal N. at the Foramen Lacerum to form the N. of Pterygoid Canal 3. N. to Pterygoid Canal goes through the canal and enters the Pterygopalatine Fossa 4. The parasymathetic fibers from the N. to pterygoid canal synapse in Pterygopalatine ganglion 5. The postsynaptic fibers leave the ganglion and innervate the Lacrimal gland via V2's zygomatic branch and V1's lacrimal branch

Describe the trajectory of Visceral parasympathetic motor to submandibular and sublingal glands by the facial N.?

1. From Superior Salivary nuceli the facial N leaves 2. Near the stylomastoid foramen the chorda tympani comes off 3. Chorda tympani crosses through the petrotympanic fissue to join V3's Lingual N. branch in the infratemporal fossa 4. The chorda tympani parasympathetic fibers synapses in the submandibular ganglion the postsynaptic fibers follow arteries to the gland

Lesions in the vestibular branch of CN VIII would likely result in what presentation?

Loss of balance Nausea Vomitting Dizziness

The glossopharyngeal N. has both motor and sensory functions. What muscle does the somatic motor function innervate? A. Parotid Gland B. Stylopharyngeus M. C. Posterior 1/3 of tongue D. None of the above

Stylopharyngeus M.

Describe the trajectory of the Glossopharyngeal N's visceral parasympathetic motor fibers to the parotid gland

1. From inferior salvitory nucleus the CN IX emerges 2. Off the CN IX arises the Tympanic N that enters the middle ear and forms a Tympanic plexus 3. The Tympanic Plexus gives off the Lesser Petrosal N. that leaves the cranium through the Foramen Ovale 4. Parasympathetic fibers synapse in the Otic Ganglion 5. Postsynaptic fibers pass to the Parotid Gland via V3's Auriculotemporal N.

What cranial nerve carries subconcious sensation from the carotid body and sinus?

Glossopharyngeal N.

The glossopharyngeal N. sends parasympathetics to the parotid gland using its postsynaptic fibers on which of the following branches? A. Auriculotemporal N. (V3) B. Lingual N. (V3) C. Zygomatic N. (V2) and Lacrimal N. (V1) D. None of the above

Auriculotemporal N. (V3)

The Facial N. gives off the chorda tympani that joins which of the following Ns. in the inframtemporal fossa on it's way to synapse on the submandibular ganglion? A. Auriculotemporal N. (V3) B. Lingual N. (V3) C. Zygomatic N. (V2) and Lacrimal N. (V1) D. None of the above

Lingual N. (V3)

When the facial n. sends parasympathetics to the lacrimal gland it meets up with which of the following branches? A. Auriculotemporal N. (V3) B. Lingual N. (V3) C. Zygomatic N. (V2) D. None of the above

Zygomatic N. (V2) - indirectly the Lacrimal N. (V1) as the Zygomatic N (v2) meets up with that one
