[Anatomy] The Head and Neck Quizzes – Part 4 (20 questions)

The hard palate is composed of the palatine processes of the maxillary bones as well as the horizontal plates of the palatine bones

Postsynaptic parasympathetic fibers pass from the ganglion to the parotid gland via the auriculotemporal nerve

Afferent fibers from the iris and cornea pass through the ciliary ganglion

The labyrinthine artery is a branch of the basilar artery, which is part of the vertebral artery system

The lateral pterygoids, when acting together, depress and protrude the mandible, with the assistance of the suprahyoid muscles, infrahyoid muscles, and gravity

The infratemporal fossa contains the otic— not the pterygopalatine—ganglion

The buccinator is a muscle of facial expression, not a muscle of mastication

The tensor tympani is innervated by the mandibular division of the trigeminal nerve

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 tensor veli palatini tenses the soft palate and opens the mouth of the auditory tube during swallowing and yawning

The sphenopalatine artery is transmitted through the sphenopalatine foramen along withthe nasopalatine and superior nasal nerves

The infraorbital artery is a branch of the third part of the maxillary artery

The muscles of mastication are associated with the first branchial arch and are innervated by the trigeminal nerve

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

The temporomandibular joint is a modified hinge-type synovial joint

The tensor veli palatini is innervated by the medial pterygoid nerve, which is a branch of the mandibular division of the trigeminal nerve

The four types of lingual papillae are the vallate papillae, foliate papillae, filiform papillae, and fungiform papillae

The artery of the pterygoid canal supplies the superior part of the pharynx, the auditory tube, and the tympanic cavity

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

The descending palatine artery is a branch of the third (pterygopalatine) part of the maxillary artery
