• A. Masseter
• B. Buccinator
• C. Middle temporal
• D. Medial pterygoid

Explanation: The masseter arises partly from the zygomatic process of the maxilla and the zygomatic arch, then inserts on the lateral ramus and angle…

• A. side of the skull

• B. Lateral surface of medial pterygoid plate
• C. Medial surface of medial pterygoid plate
• D. Lateral surface of lateral pterygoid plate

Explanation: The medial pterygoid takes its deep head mainly from the medial surface of the lateral pterygoid plate, with additional origin from nearby…

• A. Medial ( INTERNAL) pterygoid muscle
• B. Lateral (EXTERNAL) Pterygoid muscle
• C. Masseter muscle
• D. Temporalis muscle

Explanation: The lateral pterygoid pulls the mandibular condyle and articular disc forward, producing protrusion and assisting depression of the…

• A. Buccinator
• B. Temporalis
• C. Ganinus
• D. Lateral pterygoid

Explanation: Temporalis elevates the mandible through its vertical fibres and retracts it through its posterior fibres.

• A. Sternomastoid
• B. Platysma
• C. Digastric
• D. Trapezius

Explanation: The sternocleidomastoid is the major surface landmark dividing the neck into anterior and posterior triangles.

• A. Levator palpebrae superioris
• B. Orbicularis oculi
• C. Constrictor pupili
• D. Dilator pupili

Explanation: Facial palsy damages the facial nerve, paralysing muscles of facial expression such as orbicularis oculi and causing inability to close…

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

Explanation: Retraction of the mandible is mainly performed by the posterior fibres of temporalis, which pull the mandibular condyle backward.

• A. SO and IR
• B. SR and 10
• C. LR and SR
• D. MR and SR

Explanation: Elevation of the eyeball is produced by the superior rectus and inferior oblique muscles.

• A. Buccinator
• B. Depressor anguli oris
• C. Mentalis
• D. Platysma

Explanation: Platysma arises from fascia over the upper thorax and shoulder and inserts into the mandible and lower face, rather than originating from…

• A. Foramen lacerum
• B. Foramen rotundum
• C. Foramen spinosum
• D. Foramen ovale

Explanation: The accessory meningeal artery enters the cranial cavity through the foramen ovale, often accompanying the mandibular nerve.

• A. Oculomotor nerve
• B. Optic
• C. Ophthalmic division of trigeminal
• D. Trochlear

Explanation: The optic nerve passes through the optic canal, not the superior orbital fissure.

• A. Foramen rotundum
• B. Foramen lacerum
• C. Juglar foramen
• D. Zygomatic nerve

Explanation: The jugular foramen is an opening in the posterior cranial fossa and is present by childhood.
