- C. Facial
- D. Maxillary
Explanation: Tensor tympani is a first-arch muscle supplied by the mandibular division of the trigeminal nerve, usually through the nerve to medial…
Correct answer: Mandibular- A. Facial nerve
- B. Mandibular division of the trigeminal nerve
- C. Maxillary division of the trigeminal nerve
- D. Opthalmic branch of the trigeminal
Explanation: The lower molar teeth receive sensory fibres through the inferior alveolar nerve, a branch of the mandibular division of the trigeminal…
Correct answer: Mandibular division of the trigeminal nerve- A. Sphenopalatine ( pterygo palatine)
- B. Otic ganglion
- C. Submandibular
- D. Ciliary
Explanation: Secretomotor fibres to the lacrimal gland relay in the pterygopalatine ganglion before reaching the gland via branches that join the…
Correct answer: Sphenopalatine ( pterygo palatine)- A. VIII cranial nerve
- B. V cranial nerve
- C. VII cranial nerve
- D. II cranial nerve
Explanation: Temporalis is a muscle of mastication supplied by the deep temporal nerves from the mandibular division of cranial nerve V.
Correct answer: V cranial nerve- A. Foramen spinosum
- B. Foramen magnum
- C. Foramen ovale
- D. Foramen lacerum
Explanation: The motor root of the trigeminal nerve joins the mandibular division, and V3 exits the skull through the foramen ovale.
Correct answer: Foramen ovale- A. Mylohyoid , anterior and posterior belly of digastric
- B. Mylohyoid, anterior belly of digastric, and tensor tympani
- C. Mylohyoid, posterior belly of digastric , and tesnor tympani
- D. Mylohyoid, posterior belly of digastric, Stapedius and tensor tympani
Explanation: V3 supplies the mylohyoid, anterior belly of digastric, and tensor tympani, all linked to the first pharyngeal arch.
Correct answer: Mylohyoid, anterior belly of digastric, and tensor tympani- A. Auriculotemporal nerve
- B. Mandibular nerve
- C. Masseteric nerve and vessels
- D. Chorda tympani
Explanation: The mandibular or sigmoid notch is crossed by the masseteric nerve and accompanying vessels as they pass from the infratemporal fossa to…
Correct answer: Masseteric nerve and vessels- A. Stapedius
- B. Buccinator
- C. Tensor veli palatine
- D. Posterior belly of digastric
Explanation: Tensor veli palatini is the only palatal muscle supplied by V3, through the nerve to medial pterygoid.
Correct answer: Tensor veli palatine- A. Zygomaticofacial
- B. Zygmoaticotemporal
- C. Auriculotemporal
- D. Infra trochlear
Explanation: The zygomaticofacial nerve, a branch of the maxillary division of the trigeminal nerve, emerges through the zygomatic bone to supply skin…
Correct answer: Zygomaticofacial- A. Posterior ethmoidal nerve
- B. Posterior superior alveolar nerve
- C. Sphenoidal nerve
- D. Infratemporal nerve
Explanation: The posterior ethmoidal nerve, a branch of the ophthalmic division of the trigeminal nerve, supplies the sphenoidal air sinus.
Correct answer: Posterior ethmoidal nerve- A. Nasopalatine nerve
- B. Posterior ethmoidal nerve
- C. Pterygopalatine ganglion
- D. Nasociliary nerve
Explanation: The posterior ethmoidal nerve mainly supplies the posterior ethmoid air cells and sphenoidal sinus, not the nasal septum.
Correct answer: Posterior ethmoidal nerve- A. Ovale
- B. Rotundum
- C. Stylomastoid
- D. Inferior orbital fissure
Explanation: The maxillary nerve is the second division of the trigeminal nerve and leaves the middle cranial fossa through the foramen rotundum.
Correct answer: Rotundum- A. Lingual, facial and palatine nerve
- B. Lingual and inferior alveolar nerves
- C. Inferior alveolar and cervical nerves
- D. All of the above
Explanation: The lingual and inferior alveolar nerves are major branches of the mandibular division of the trigeminal nerve.
Correct answer: Lingual and inferior alveolar nerves- A. Masseter
- B. Buccinator
- C. Medial pterygoid
- D. Anterior belly of digastric
Explanation: Buccinator is a muscle of facial expression supplied by the facial nerve, despite its location in the cheek.
Correct answer: Buccinator- A. Ala of the nosa and lower eyelid
- B. The upper cheeks
- C. Gingiva of the maxilla
- D. Temporomandibular joint
Explanation: The maxillary nerve supplies the midface, including the ala of the nose, lower eyelid, upper cheek, and maxillary gingiva.
Correct answer: Temporomandibular joint- A. Foramen ovale
- B. Foramen rotundum
- C. Superior orbital fissure
- D. Stylomastoid foramen
Explanation: The trigeminal divisions pass through the foramen ovale, foramen rotundum, and superior orbital fissure.
Correct answer: Stylomastoid foramen- A. Occulomotor
- B. Trochlear
- C. Trigeminal
- D. Ophthalmic
Explanation: The superior oblique muscle depresses and abducts the eye, producing downward and lateral movement, and is supplied by the trochlear…
Correct answer: Trochlear- A. Occulomotor
- B. Trochlear
- C. Trigeminal
- D. Ophthalmic
Explanation: The lateral wall of the cavernous sinus contains cranial nerves III, IV, and the ophthalmic and maxillary divisions of V.
Correct answer: Trigeminal- A. Lateral rectus
- B. Superior oblique
- C. Superior rectus
- D. A & B
Explanation: The oculomotor nerve supplies superior, medial and inferior recti, inferior oblique and levator palpebrae.
Correct answer: A & B- A. Trochlear nerve
- B. Occulomotor
- C. Trigeminal nerve
- D. Superior oblique muscle
Explanation: Most levator palpebrae fibres are supplied by the oculomotor nerve, so its injury produces ptosis.
Correct answer: Occulomotor
