PARTS I and II. Circle statements that are correct. (10 pts (½ pt ea))

Lecture 37: Cervical Fascia (L. Evey)

  1. The pretracheal space can spread infection to the superior mediastinum and the retropharyngeal space can spread infection to the posterior mediastinum.
  2. A puncture would to the oral pharynx invades the retropharyngeal space before invading the prevertebral space.
  3. Infections within the cervical spaces are indicated by stridor.

Lecture 38: Triangles of the Neck (N. Yoshioka)

  1. The nerve to mylohyoid is a branch off the hypoglossal nerve within the submandibular triangle, and supplies SVE innervation to both mylohyoid and the anterior belly of digastric.
  2. The ansa cervicalis can be distinguished from the right recurrent laryngeal nerve because it travels anterior to the subclavian artery.
  3. The great auricular nerve provides SVE innervation to the auricularis and GSA innervation to the opening of the external acoustic meatus.

Lecture 39: Skull and Face (M. Jennette)

  1. Muscles in the circumorbital/palpebral group are innervated by the temporal and zygomatic branches of the facial nerve
  2. Muscles that elevate the upper lip are innervated by the zygomatic and buccal branches of the facial nerve

Lecture 40: Introduction to Cranial Nerves (D. Rasicci)

  1. The ophthalmic division of the trigeminal nerve (V1) subserves the afferent limb of the corneal blink reflex.
  2. Iatrogenic injury to the right recurrent laryngeal nerve may result in ipsilateral vocal fold paralysis.
  3. A lesion of the right hypoglossal nerve (CN XII) causes tongue deviation to the contralateral (left) side of the lesion.

Lecture 41: Temporal Region and Infratemporal Fossa (A. Ricci)

  1. The inferior alveolar nerve travels through the mandibular foramen and canal.
  2. The mandibular nerve goes through the foramen spinosum to enter the infratemporal fossa.
  3. The medial pterygoid muscle and lateral pterygoid muscle are contents of the infratemporal fossa.

Lecture 42: Parotid Region and Temporomandibular Joint(L. Urbanik)

  1. Translational movements (protraction and retraction) are predominately movements of the superior synovial cavity.
  2. The posterior auricular nerve emerges prior to the facial nerve entering the parotid gland.

Lecture 43: Cranial Fossa and Interior of the Skull (L. Evey)

  1. The posterior opening of the pterygoid canal is into the region of the lacerate foramen within the cavernous sinus.
  2. The intracranial region of the pterion is grooved by the posterior branch of the middle meningeal artery.

Lecture 44: Dural Venous Sinuses (L. Evey)

  1. The sphenoparietal sinus is located along the lesser wing of the sphenoid bone and drains into the cavernous sinus.
  2. The basilar venous plexus communicates with the inferior petrosal sinus and with the marginal sinus.

Lecture 45: Gross Anatomy of the Brain (A. Ricci)

  1. The trigeminal nerve arises from the pons.
  2. The cerebral aqueduct connects the 3rd and 4th ventricles.
  3. The post-central gyrus is also known as primary motor cortex.

Lecture 46: Placeholder

  1. enumerated item
  2. enumerated item

Lecture 47: Cranial Nerves (L. Evey)

  1. Unilateral cavernous sinus thrombosis/infection is indicated by adduction of the contralateral eye.
  2. Pituitary adenoma is indicated by tunnel vision.

Lecture 48: Globe (M. Olsen)

  1. The depression in the center of the optic disc is called the fovea centralis.
  2. The nasolacrimal duct extends inferiorly from the lacrimal sac and opens into the superior meatus of the nasal cavity.
  3. Aqueous humor is absorbed into the scleral venous sinus (the canal of Schlemm).

Lecture 49: Orbit (D. Mehay)

  1. The lateral rectus muscle adducts the globe and is the sole innervation of the abducens nerve.
  2. The superior oblique muscle moves the globe in abduction, depression, and medial rotation (intorsion).
  3. The frontal nerve, lacrimal nerve, and trochlear nerve all enter the orbit without passing through the annulus tendineus.

Lecture 50: Larynx (J. Radler)

  1. Contraction of the cricothyroid muscle rocks the thyroid cartilage anterior with respect to the cricoid cartilage, causing decreased tension of the true vocal folds.
  2. The internal branch of the superior laryngeal nerve pierces the cricothyroid membrane to enter the larynx.
  3. During whispering the true vocal folds are adducted and air escapes between the arytenoid cartilages. There is no vibration of the vocal folds.

Lecture 51: Pharynx (C. Werner)

  1. The levator veli palatini, tensor veli palatini, and salpingopharyngeus muscles contribute to the movements of swallowing and to the equalization of air pressure in the middle ear.
  2. The gag reflex is mediated by the GVA component of the glossopharyngeal nerve.
  3. The median and lateral glossoepiglottic folds define the vallecula.

Lecture 52: Prevertebral Region (L. Evey)

  1. Gray rami that connect to the roots of the brachial plexus are from the stellate (upper thoracic and lower cervical sympathetic trunk ganglia) and the superior cervical sympathetic trunk ganglia.
  2. The phrenic nerve descends along the anterior surface of the anterior scalene muscle deep to the prevertebral fascia and, therefore, may be affected by brachial plexus anesthesia within the axillary sheath.

Lecture 53: Temporal Bone (A. Ricci)

  1. The tympanic canaliculus transmits the recurrent tympanic nerve.
  2. The mucosa of the tympanic cavity is innervated by the recurrent tympanic nerve and tympanic plexus.
  3. The carotid canal transmits the external carotid artery.

Lecture 54: Pterygopalatine Fossa (L. Evey)

  1. The pterygomaxillary fissure provides a bony communication between the pterygopalatine fossa and the infratemporal fossa.
  2. The pterygoid canal provides a bony communication between the pterygopalatine fossa and the middle cranial fossa.
