- A. Occulomotor ( III) nerve
- B. Traochlear nerve
- C. Medial cerebral artery
- D. Trigeminal nerve
Explanation: The cavernous sinus contains cranial nerves III, IV, V1 and V2 in its lateral wall, together with the internal carotid artery and abducens…
Correct answer: Medial cerebral artery- A. Tendon of levator veli palatine muscle
- B. Tendon of Tensor veli palatine muscle
- C. A part of musculus uvulae
- D. A modification of palatal periosteum
Explanation: The palatine aponeurosis is formed mainly by the expanded tendon of tensor veli palatini, which spreads into the soft palate.
Correct answer: Tendon of Tensor veli palatine muscle- A. External laryngeal
- B. Recurrent laryngeal
- C. Internal laryngeal
- D. Glossopharyngeal
Explanation: The internal laryngeal nerve supplies sensation to the laryngeal mucosa above the vocal folds and reaches the vocal-fold region.
Correct answer: Internal laryngeal- A. Sternohyoid
- B. Omohyoid
- C. Stenothyroid
- D. Thyrohyoid
Explanation: Ansa cervicalis supplies sternohyoid, omohyoid and sternothyroid. Thyrohyoid is supplied directly by C1 fibres travelling with the…
Correct answer: Thyrohyoid- A. Great auricular nerve
- B. Lesser occipital nerve
- C. Greater occipital nerve
- D. Posterior auricular nerve
Explanation: The great auricular nerve, from the cervical plexus, supplies skin over the angle of the mandible and the lower part of the auricle.
Correct answer: Great auricular nerve- A. C2C3C4
- B. C1C2C3
- C. C3C4C5
- D. C4C5C6
Explanation: The phrenic nerve is formed chiefly by the anterior rami of C3, C4 and C5, with C4 providing the major contribution.
Correct answer: C3C4C5- A. Left hypoglossal
- B. Left glossopharyngeal
- C. Right hypoglossal
- D. Right glossopharyngeal
Explanation: Protrusion is produced mainly by the genioglossus muscles, and unilateral weakness causes the tongue to deviate toward the weak side.
Correct answer: Left hypoglossal- A. Motor innervation to styloglossus and hyoglossus muscles only
- B. Motor innervation to all of the muscles of the tongue both intrinsic and extrinsic
- C. Sensory innervation to the posterior third of the tongue
- D. Sensory innervation to the anterior two - thirds of the tongue
Explanation: The hypoglossal nerve supplies motor fibres to all intrinsic and extrinsic tongue muscles except palatoglossus.
Correct answer: Motor innervation to all of the muscles of the tongue both intrinsic and extrinsic- A. Hyoglossus
- B. Styloglossus
- C. Genioglossus
- D. Palatoglossus
Explanation: Hypoglossal nerve supplies hyoglossus, styloglossus, genioglossus and the intrinsic tongue muscles.
Correct answer: Palatoglossus- A. One
- B. Two
- C. More than two
- D. None of the above
Explanation: The vagus is the only cranial nerve that extends beyond the head and neck, carrying parasympathetic fibres into the thorax and abdomen.
Correct answer: One- A. External laryngeal
- B. Internal laryngeal
- C. Recurrent laryngeal
- D. B & C
Explanation: The internal laryngeal nerve supplies sensation above the vocal folds, while the recurrent laryngeal nerve supplies mucosa below them.
Correct answer: B & C- A. Hoarseness
- B. Loss of timbre of voice
- C. Anesthesia of the larynx
- D. Breathing difficulty
Explanation: The internal laryngeal nerve is the sensory nerve of the larynx above the vocal folds, so its damage causes loss of laryngeal sensation…
Correct answer: Anesthesia of the larynx- A. Internal carotid artery
- B. 12th cranial nerve
- C. Vagus nerve
- D. Accessory cranial
Explanation: The vagus nerve leaves the head and neck and continues through the thorax into the abdomen, supplying or contributing to innervation of…
Correct answer: Vagus nerve- A. Vagus nerve
- B. Glossopharyngeal nerve
- C. Accessory nerve
- D. Internal carotid artery
Explanation: The jugular foramen transmits cranial nerves IX, X and XI along with venous structures.
Correct answer: Internal carotid artery- A. Maxillary division of the trigeminal nerve
- B. Facial nerve
- C. Glossopharyngeal nerve
- D. Hypoglossal nerve
Explanation: Palatal sensation is carried mainly by branches of the maxillary nerve, with contributions from glossopharyngeal-related pharyngeal…
Correct answer: Hypoglossal nerve- A. Stylopharyngeus
- B. Palatophary negus
- C. Geniohyoid
- D. Genioglossus
Explanation: Glossopharyngeal nerve supplies the stylopharyngeus, the only muscle receiving motor innervation from cranial nerve IX.
Correct answer: Stylopharyngeus- A. Facial nerve
- B. Glossopharyngeal nerve
- C. Trigeminal nerve
- D. None of the above
Explanation: Preganglionic parasympathetic fibres arise from the glossopharyngeal nerve, pass through the tympanic and lesser petrosal nerves, and…
Correct answer: Glossopharyngeal nerve- A. Lacrimal gland
- B. Nasal gland
- C. Submandibular gland
- D. Parotid gland
Explanation: The facial nerve carries parasympathetic fibres to the lacrimal, nasal and submandibular glands.
Correct answer: Parotid gland- A. Arises from the medulla oblongata
- B. Transverses through parotid gland
- C. Suppleis muscles of mastication
- D. Carries no taste fibres
Explanation: The facial nerve emerges at the pontomedullary junction and passes through the parotid gland, where it forms its terminal branches.
Correct answer: Transverses through parotid gland- A. Chorda tympani nerve
- B. Deep peterosal nerve
- C. Greater petrosal nerve
- D. Lesser petrosal nerve
Explanation: Preganglionic parasympathetic fibres for lacrimation leave the facial nerve in the greater petrosal nerve and synapse in the…
Correct answer: Greater petrosal nerve
