Explanation: The intrinsic muscles of the eye include sphincter pupillae, dilator pupillae, and ciliary muscle.

• A. Swallowing and speech
• B. Swallowing and smiling
• C. Swallowing and chewing

Explanation: The posterior belly of digastric elevates and retracts the hyoid during swallowing and assists mandibular movements used in chewing.

• A. Superior constrictor
• B. Inferior constrictor
• C. Thyrohyoid

Explanation: The hypoglossal nerve is a motor cranial nerve supplying the intrinsic and most extrinsic muscles of the tongue.

• A. Muscle fibres in the liqament of Treitz
• B. Omohyoid
• C. Occipitofrontalis
• D. Sternocleidomastoid

Explanation: A digastric muscle has two distinct muscular bellies, as seen in omohyoid and occipitofrontalis; the suspensory muscle associated with the…

• A. Palatoglossus
• B. Tensor veli palatini
• C. Levator veli palatini
• D. Palatopharyngeus

Explanation: Tensor veli palatini forms a tendon that turns around the pterygoid hamulus before spreading into the palatal aponeurosis.

• A. Lateral temporomandibular ligament
• B. Sphenomandibular ligament
• C. Stylomandibular liqament
• D. Alar liqament

Explanation: The temporomandibular joint has an intrinsic lateral ligament and is supported by the sphenomandibular and stylomandibular ligaments.

• A. Mental spines
• B. Superior genial tubercle
• C. The inferior genial tubercle
• D. Just above the lower border of mandible

Explanation: Genioglossus arises from the superior genial tubercle, also called the superior mental spine, on the posterior surface of the mandibular…

• A. Anterior belly of the diagstric
• B. Posterior belly of the digastric
• C. Superior belly of omohyoid
• D. Sternothyroid

Explanation: The posterior belly of digastric forms the upper boundary separating the carotid triangle from the digastric, or submandibular, triangle.

• A. Condylar process
• B. Coronioid process
• C. Linguula
• D. Ramus of mandible nerve

Explanation: Temporalis converges onto the coronoid process and the anterior border of the mandibular ramus.

• A. 1st branchial arch
• B. 2ndbranchial arch
• C. 3rdbranchial arch
• D. 4thbranchial arch

Explanation: The muscles of facial expression develop from the second pharyngeal arch and therefore are supplied by the facial nerve.

• A. Grannial accessory
• B. Spinal accessory
• C. Vagus
• D. Glossopharyngeal

Explanation: The spinal accessory nerve supplies both sternocleidomastoid and trapezius.

• A. Palatoglossus
• B. Palatopharyngeus
• C. Styloglossus
• D. Superior constrictor

Explanation: Passavant’s muscle is classically identified with the palatopharyngeus, whose contraction helps form Passavant’s ridge during swallowing.

• A. Styloid
• B. Hyoid
• C. Mastoid notch
• D. Thyroid

Explanation: The posterior belly of digastric arises from the mastoid notch of the temporal bone and runs toward the hyoid via its intermediate tendon.

• A. Inferior oblique
• B. Inferior rectus
• C. Superior oblique
• D. lateral rectus

Explanation: Inferior rectus depresses the eye, opposing the elevation produced by superior rectus.

• A. Facial
• B. Vagus
• C. Glossopharyngeal
• D. Trochlear

Explanation: Stapedius is supplied by the nerve to stapedius, a branch of the facial nerve. Its contraction dampens excessive movement of the stapes.

• A. Orbicularis oris
• B. Styloglossus
• C. Stylopharyngeus
• D. Stapedius

Explanation: Stapedius normally limits excessive stapes movement; its paralysis causes hyperacusis, in which ordinary sounds seem abnormally loud.
