Parasympathetic fibers from CN IX synapse in which ganglion before traveling to the parotid gland?

Correct! Wrong!

Parasympathetic fibers from CN IX synapse in the otic ganglion before traveling to the parotid gland

Which of the following lists the layers of the scalp in the correct order?

Correct! Wrong!

The scalp is composed of skin, connective tissue, aponeurosis, loose connective tissue, and pericranium

Which of the following descriptions is correct?

Correct! Wrong!

The cavernous sinus is situated on each side of the sella turcica. It extends on each side from the superior orbital fissure to the petrous part of the temporal bone

The cavernous sinus receives blood from all of the following EXCEPT

Correct! Wrong!

The cavernous sinus receives blood from the superior ophthalmic veins, the inferior ophthalmic veins, the superficial middle cerebral vein, and the sphenoparietal sinus

Which of the following nerves is NOT contained within the cavernous sinus?

Correct! Wrong!

The cavernous sinus contains the internal carotid artery with its small branches, the carotid plexus of sympathetic nerves, the oculomotor nerve, the trochlear nerve, the trigeminal nerve (the ophthalmic division and occasionally the maxillary division), and the abducent

Which of the following does NOT contribute to innervation of the dura mater?

Correct! Wrong!

The dura mater is innervated by all three divisions of the trigeminal nerve, C1–C3, and possibly the vagus nerve

Which of the following is correct in respect to the brain?

Correct! Wrong!

The cavity of the medulla oblongata forms the inferior part of the fourth ventricle

Which of the following correctly describes the flow of cerebrospinal fluid?

Correct! Wrong!

Cerebrospinal fluid flows from each lateral ventricle through an interventricular foramen into the 3rd ventricle, then through the cerebral aqueduct into the 4th ventricle, and finally through median and lateral apertures into the subarachnoid space

Which of the following is true regarding the carotid canal?

Correct! Wrong!

The carotid canal is located in the inferior surface of the petrous temporal bone in the middle cranial fossa and contains the internal carotid artery, sympathetic plexus, and internal carotid venous plexus

Which of the following foramina is unpaired?

Correct! Wrong!

The foramen cecum is unpaired

The oculomotor nerve emerges between which two arteries of the cerebral arterial circle?

Correct! Wrong!

The oculomotor nerve emerges between the superior cerebellar artery and the posterior cerebral artery

What nerve emerges between the labyrinthine artery and the anterior inferior cerebellar artery?

Correct! Wrong!

The abducent nerve emerges between the labyrinthine artery and the anterior inferior cerebellar artery

Which artery is NOT a branch of the vertebral artery system?

Correct! Wrong!

The vertebral artery system has the following branches: posterior communicating, posterior cerebral, basilar, superior cerebellar, anterior inferior cerebellar, posterior inferior cerebellar, labyrinthine, and anterior spinal. The ophthalmic artery is a branch of the internal carotid artery system

Which of the following arteries is correctly matched with its distribution?

Correct! Wrong!

The middle meningeal artery supplies more blood to the calvaria than to the dura, which is supplied by the vertebral artery

Which of the following lists best describes the pathway of tears from the lacrimal glands to the nasal cavity?

Correct! Wrong!

Tears flow from the lacrimal ducts across the eye to the lacrimal lake. The tears then pass through the lacrimal punctum on the lacrimal papilla, into the lacrimal canaliculi, and into the lacrimal sac, which is the widened end of the nasolacrimal duct

Which of the following best describes the pathway of parasympathetic fibers to the lacrimal gland?

Correct! Wrong!

Parasympathetic fibers from CN VII travel first via the greater petrosal nerve and then via the nerve of the pterygoid canal to the pterygopalatine ganglion, where they synapse with postsynaptic fibers. These fibers join the zygomatic branch of V2, which in turn conveys the fibers to the lacrimal branch of V1 (via a communicating branch). This nerve delivers the parasympathetic fibers to the lacrimal gland

Which of the following muscles does NOT take its origin from the common tendinous ring?

Correct! Wrong!

The superior oblique takes its origin from the body of the sphenoid bone, while all four rectus muscles take origin from the common tendinous ring

Which of the following muscles is NOT innervated by the oculomotor nerve?

Correct! Wrong!

The lateral rectus is innervated by the abducent nerve

Which of the following muscles is NOT properly matched with it main action?

Correct! Wrong!

The superior oblique abducts, depresses, and rotates the eyeball medially

Which of the following nerves is correctly matched with its distribution?

Correct! Wrong!

The long ciliary nerves convey postsynaptic sympathetic fibers to the dilator pupillae and afferent fibers from the iris and cornea
