Foramen ovale
Jugular foramen
Stylomastoid foramen
Foramen rotundum
2. Excluding the vallate papillae, taste from the anterior two-thirds of the tongue is carried primarily by which nerve?
Chorda tympani
Glossopharyngeal nerve
Greater petrosal nerve
Lingual nerve
3. A lesion at the foramen ovale would most directly affect which cranial nerve division?
Ophthalmic division of the trigeminal nerve
Maxillary division of the trigeminal nerve
Facial nerve
Mandibular division of the trigeminal nerve
4. A scalp laceration bleeds heavily and the cut vessels remain open. Which feature of the scalp best explains this?
Loose areolar tissue permits extensive vessel retraction
Dense connective tissue holds the severed vessels open
The epicranial aponeurosis contains large venous sinuses
The pericranium prevents arterial vasoconstriction
5. A blow fractures the skull at the pterion and produces an epidural hematoma. Which vessel was most likely torn?
Superficial temporal artery
Middle meningeal artery
Occipital artery
Maxillary artery
6. Which set of structures is contained within the carotid sheath?
Carotid artery, internal jugular vein, and vagus nerve
External jugular vein, sympathetic trunk, and phrenic nerve
Carotid artery, ansa cervicalis, and hypoglossal nerve
Internal jugular vein, recurrent laryngeal nerve, and sympathetic trunk
7. A lesion within the cavernous sinus affects the cranial nerve that runs beside the internal carotid artery rather than in the sinus's lateral wall. Which nerve is it?
Oculomotor nerve
Abducens nerve
Trochlear nerve
Ophthalmic nerve
8. An infection from the facial 'danger triangle' spreads through valveless venous connections into the cranial cavity. Which structure is the classic intracranial destination?
Straight sinus
Cavernous sinus
Superior sagittal sinus
Transverse sinus
9. Following a lymph-node biopsy in the posterior triangle, a patient has a drooping shoulder and difficulty shrugging against resistance. Which structure was most likely injured?
Dorsal scapular nerve supplying the rhomboids
Long thoracic nerve supplying serratus anterior
Suprascapular nerve supplying supraspinatus
Accessory nerve supplying trapezius
10. A patient has a typical anterior nosebleed arising from Kiesselbach's plexus. Where should the clinician expect to find the bleeding site?
Roof of the nasal cavity
Posterior end of the inferior concha
Anterior nasal septum
Lateral wall of the nasopharynx
11. During parotid gland surgery, which nerve is especially at risk because it branches within the gland?
Glossopharyngeal nerve
Hypoglossal nerve
Facial nerve
Phrenic nerve
12. A lower motor neuron lesion of the right hypoglossal nerve weakens the right genioglossus muscle. When protruded, in which direction will the tongue deviate?
Downward without lateral deviation
Toward the left side
Upward without lateral deviation
Toward the right side
13. Which nerve carries general sensation from most of the anterior two-thirds of the tongue?
Glossopharyngeal nerve
Chorda tympani
Greater palatine nerve
Lingual nerve
14. After thyroid surgery, a patient can speak but has difficulty producing high-pitched sounds because the cricothyroid muscle is weak. Which nerve was most likely injured?
Internal branch of the superior laryngeal nerve
Recurrent laryngeal nerve
External branch of the superior laryngeal nerve
Hypoglossal nerve
15. A deep neck infection enters the potential space that can provide a pathway from the skull base toward the mediastinum and diaphragm. Which space is this?
Danger space
Masticator space
Parotid space
Sublingual space
16. Where does the submandibular duct normally open into the oral cavity?
At the sublingual caruncle beside the lingual frenulum
Into the tonsillar fossa
Along the posterior edge of the hard palate
Opposite the maxillary second molar
