• 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.

• A. Masseter
• B. Medial pterygoid
• C. Temporalis
• D. Digastric

Explanation: The medial pterygoid elevates and assists protrusion of the mandible, while unilateral contraction produces rotation toward the opposite…

• A. Arises from hyoid bone
• B. developed from second pharyngeal arch
• C. Depresses the hyoid
• D. Elevates the hyoid

Explanation: Mylohyoid is a first-pharyngeal-arch muscle that elevates the hyoid and floor of the mouth; it arises from the mylohyoid line of the…

• A. Buccinator
• B. Masseter
• C. Temporalis
• D. Pterygoids

Explanation: The four muscles of mastication are masseter, temporalis, medial pterygoid and lateral pterygoid.

• A. Depression of mandible
• B. Protrusion of mandible
• C. Side- to- side movement of mandible
• D. Depressing the floor of the mouth

Explanation: When the hyoid is fixed, the digastric muscle depresses the mandible and helps open the mouth.

• A. Genioglossus
• B. Geniohyoid
• C. Mylohyoid
• D. Masseter

Explanation: The mylohyoid muscles form the muscular floor of the mouth, extending from the mylohyoid lines of the mandible to the hyoid and median…

• A. Mylohyoid muscle
• B. Genioglossus muscle
• C. Buccinator muscle
• D. Orbicularis oris muscle

Explanation: The paired mylohyoid muscles form the oral diaphragm, a muscular sling that supports the floor of the mouth and separates it from the…

• A. Hypoglossal nerve
• B. Lingual artery
• C. Stylohyoid muscle
• D. Geniohyoid muscle

Explanation: The lingual artery lies deep to hyoglossus, whereas the hypoglossal nerve passes superficially over its lateral surface.

• A. Levator palatine
• B. Palatopharyngeus
• C. Tensor palatine
• D. Stylopharyngeus

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

• A. Ansa cervicalis
• B. Hypoglossal nerve
• C. Tenth cranial nerve
• D. Ansa sublavia

Explanation: Ansa cervicalis supplies most infrahyoid muscles, including sternohyoid, sternothyroid and omohyoid.
