Which of the following depresses the mandible?
The lateral pterygoids, when acting together, depress and protrude the mandible, with the assistance of the suprahyoid muscles, infrahyoid muscles, and gravity
Which of the following is NOT true in respect to the sphenopalatine artery?
The sphenopalatine artery is transmitted through the sphenopalatine foramen along withthe nasopalatine and superior nasal nerves
Which of the following branches of the third (pterygopalatine) part of the maxillary artery is correctly paired with its distribution?
The artery of the pterygoid canal supplies the superior part of the pharynx, the auditory tube, and the tympanic cavity
The muscles of mastication are associated with which branchial arch?
The muscles of mastication are associated with the first branchial arch and are innervated by the trigeminal nerve
Which of the following is NOT a type of lingual papilla?
The four types of lingual papillae are the vallate papillae, foliate papillae, filiform papillae, and fungiform papillae
Which of the following palate muscles is NOT innervated by the cranial part of the accessory nerve through a pharyngeal branch of the vagus nerve via the pharyngeal plexus?
The tensor veli palatini is innervated by the medial pterygoid nerve, which is a branch of the mandibular division of the trigeminal nerve
Which of the following is NOT contained in the infratemporal fossa?
The infratemporal fossa contains the otic— not the pterygopalatine—ganglion
Which of the following is correctly matched with its action?
The tensor veli palatini tenses the soft palate and opens the mouth of the auditory tube during swallowing and yawning
Which of the following is NOT a branch of the second (pterygoid) part of the maxillary artery?
The labyrinthine artery is a branch of the basilar artery, which is part of the vertebral artery system
Which of the following arteries is NOT a branch of the ophthalmic artery?
The infraorbital artery is a branch of the third part of the maxillary artery
Which of the following is NOT a branch of the first (mandibular) part of the first part of the maxillary artery?
The descending palatine artery is a branch of the third (pterygopalatine) part of the maxillary artery
Which of the following tongue muscles is correctly paired with its action?
The genioglossus depresses the tongue and assists in protrusion. The hyoglossus depresses and retracts the tongue. The styloglossus retracts the tongue and draws it up for swallowing. The palatoglossus elevates the posterior part of the tongue. The superior and inferior longitudinal muscles curl the tip and sides of the tongue and shorten it. The transverse narrows and elongates the tongue, assisting in protrusion. The vertical flattens and broadens the tongue, assisting in protrusion
The temporomandibular joint is what type of joint?
The temporomandibular joint is a modified hinge-type synovial joint
Which of the following muscles is NOT a muscle of mastication?
The buccinator is a muscle of facial expression, not a muscle of mastication
Which nerve is NOT correctly matched with its distribution?
The tensor tympani is innervated by the mandibular division of the trigeminal nerve
Which of the following is true in respect to the ciliary ganglion?
Afferent fibers from the iris and cornea pass through the ciliary ganglion
Which of the following arteries is correctly paired with its course and distribution?
The short posterior ciliary arteries pierce the sclera near the optic nerve and supply the choroid, which subsequently supplies the rods and cones of the retina
Which of the following muscles is NOT innervated by the hypoglossal nerve?
The hypoglossal nerve innervates the four intrinsic muscles of the tongue in addition to the following three extrinsic muscles of the tongue: genioglossus, hyoglossus, and styloglossus. The vagus innervates the palatoglossus, which is both an extrinsic tongue muscle and a palate muscle
Which of the following is true in respect to the otic ganglion?
Postsynaptic parasympathetic fibers pass from the ganglion to the parotid gland via the auriculotemporal nerve
Which of the following is correct in respect to the hard palate?
The hard palate is composed of the palatine processes of the maxillary bones as well as the horizontal plates of the palatine bones
