- 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…
Correct answer: Medial pterygoid- 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…
Correct answer: Elevates the hyoid263. All of the following muscles are grouped together as "muscles of mastication" except_______________?
- A. Buccinator
- B. Masseter
- C. Temporalis
- D. Pterygoids
Explanation: The four muscles of mastication are masseter, temporalis, medial pterygoid and lateral pterygoid.
Correct answer: Buccinator- 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.
Correct answer: Depression of mandible- 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…
Correct answer: Mylohyoid- 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…
Correct answer: Mylohyoid muscle- 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.
Correct answer: Hypoglossal nerve- 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.
Correct answer: Tensor palatine- 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.
Correct answer: Ansa cervicalis- A. Digastric
- B. Lateral pterygoid
- C. Masseter
- D. Temporalis
Explanation: The digastric has two muscle bellies with different nerve supplies: the anterior belly is supplied by the mylohyoid nerve, while the…
Correct answer: Digastric- A. Sphenomandibular
- B. Stylomandibular
- C. Pterygomandibular
- D. All of the above
Explanation: The stylomandibular ligament becomes taut during certain mandibular movements and helps limit excessive protrusion and opening.
Correct answer: Stylomandibular- A. Mobile
- B. Supple
- C. Immobile
- D. None of the above
Explanation: During wide opening of the mouth, the modiolus at the angle of the mouth is fixed by the coordinated pull of surrounding facial muscles.
Correct answer: Immobile- A. Tip of the tongue
- B. Base of the tongue
- C. Lateral part of the tongue
- D. Hyoid bone
Explanation: Hyoglossus arises from the hyoid bone and ascends to insert into the side of the tongue, extending toward its posterior part.
Correct answer: Lateral part of the tongue- A. Auriculotemporal nerve
- B. Facial nerve
- C. Massetric nerve
- D. Auricular nerve
Explanation: The auriculotemporal nerve, a branch of V3, provides the main sensory supply to the TMJ capsule.
Correct answer: Auriculotemporal nerve- A. Levator palati
- B. Palat glossus
- C. Tensor palati
- D. Musculus uvulae
Explanation: Tensor veli palatini is the only soft-palate muscle supplied by the mandibular division of the trigeminal nerve through the nerve to…
Correct answer: Tensor palati- A. Platysma
- B. Sternohyoid
- C. Sternocleidomastoid
- D. Omohyoid
Explanation: Wry neck, or torticollis, results from shortening or spasm of the sternocleidomastoid, producing lateral flexion and rotation of the neck.
Correct answer: Sternocleidomastoid- A. Body of hyoid bone
- B. Mandible
- C. Pterygomandibular raphae
- D. Cricoid cartilage
Explanation: The middle pharyngeal constrictor arises from the greater and lesser horns of the hyoid bone, including attachment near its body.
Correct answer: Body of hyoid bone- A. Condyles move upwards
- B. Articular disc moves posteriorly
- C. Lateral pterygoids contract
- D. Condyles moves around vertical axis
Explanation: Wide opening of the jaw requires contraction of the lateral pterygoid, which pulls the mandibular condyle and articular disc forwards onto…
Correct answer: Lateral pterygoids contract- A. Levator palpebrae superioris muscle
- B. Lateral rectus
- C. inferior oblique
- D. Superior oblique
Explanation: The lacrimal gland occupies the lacrimal fossa in the superolateral orbit, and its orbital and palpebral parts are separated by the…
Correct answer: Levator palpebrae superioris muscle- A. Condyle
- B. Stylo mandibular ligament
- C. Medial pterygoid muscle
- D. Lateral pterygoid muscle
Explanation: The lateral pterygoid pulls the articular disc and mandibular condyle forwards during protrusion and opening of the mouth.
Correct answer: Lateral pterygoid muscle
