• A. Is a point of articulation four skull bones
• B. Is a point where 'bregma' and 'lambda 'meet
• C. It is the region of the antero - lateral fontanelle merge
• D. Lies deep to the zygomatic arch

Explanation: The pterion is the junction of the frontal, parietal, temporal, and sphenoid bones, specifically near the greater wing of the sphenoid.

• A. Foramen Rotundum
• B. Canaliculus innominatus
• C. Foramen Spinosum
• D. Optic canal

Explanation: The optic canal is formed in the lesser wing of the sphenoid, whereas the foramen rotundum, foramen spinosum, and canaliculus innominatus…

• A. Serrate
• B. Denticulate
• C. Squamous
• D. Plane

Explanation: The sagittal suture has interlocking, saw-toothed margins, so it is a serrate suture.

• A. Third cervical vertebra
• B. Fourth cervical vertebra
• C. Fifth cervical vertebra
• D. Seventh cervical vertebra

Explanation: The body of the hyoid bone usually lies opposite the third cervical vertebra, or C3, in the anterior midline of the neck.

• A. Mastoid
• B. Mandible
• C. Maxilla
• D. Ethmoid

Explanation: The mandible is not a pneumatic bone because it normally contains no air-filled cavity.

• A. Mandible bone
• B. Maxilla bone
• C. Sphenoid bone
• D. Temporal bone

Explanation: The mandibular fossa is a depression on the temporal bone that receives the head of the mandible to form the temporomandibular joint.

• A. Greater palatine canal
• B. Foramen Rotundum
• C. Pterygoid canal
• D. Palatovaginal canal

Explanation: The greater palatine canal opens inferiorly from the pterygopalatine fossa and transmits the greater and lesser palatine nerves and…

• A. Posterior nasal spine
• B. Mylohyoid line
• C. Pterygoid Hamulus
• D. Greater palatine foramen

Explanation: The greater palatine foramen lies medial to the maxillary third molar, at the junction of the maxilla and horizontal plate of the palatine…

• A. Quadrangular
• B. Oval
• C. Oblong
• D. Circular

Explanation: The orbital opening is approximately quadrangular, with superior, inferior, medial, and lateral margins.

• A. Medial wall
• B. Lateral wall
• C. Floor of the orbit
• D. Roof of the orbit

Explanation: The medial orbital wall is the weakest wall because the lamina papyracea of the ethmoid is extremely thin.

• A. Mandible
• B. Nasal bone
• C. Vomer
• D. Occipital

Explanation: Among these bones, the mandible begins ossifying earliest, during the sixth week of development by intramembranous ossification.

• A. Genioglossus
• B. Anterior & Posterior bellies of digastric
• C. Mylohyoid
• D. Superior constrictor of pharynx

Explanation: The mental spines, also called genial tubercles, give attachment to the genioglossus superiorly and geniohyoid inferiorly.

• A. C2
• B. C7
• C. T10
• D. L2

Explanation: The spine of C7 is unusually long and easily palpable at the base of the neck, earning it the name vertebra prominens.

• A. Superior ophthalmic vein
• B. Ophthalmic artery
• C. Trochlear nerve
• D. Zygomatic nerve

Explanation: The zygomatic nerve, a branch of the maxillary division of the trigeminal nerve, enters the orbit through the inferior orbital fissure.

• A. Emissary vein
• B. Mandibular nerve
• C. Trigeminal nerve
• D. A & B

Explanation: The foramen ovale transmits the mandibular division of the trigeminal nerve and may also transmit an emissary vein.

• A. Lateral pterygoid
• B. Medial pterygoid
• C. Digastric
• D. Mylohyoid

Explanation: The lateral pterygoid attaches to the capsule and articular disc of the temporomandibular joint, drawing the disc forward and slightly…

• A. Lateral pterygoid plate
• B. Maxillary posterior wall
• C. Pterygomaxillary fissure
• D. Mastiod process

Explanation: The infratemporal fossa lies immediately behind the maxilla, so its anterior boundary is the posterior surface of the maxillary bone.

• A. Diploe not formed
• B. Styloid process has not fused with rest of temporal bone
• C. Anterior fontanelle open
• D. Mastoid process is of adult size

Explanation: A newborn skull lacks a fully developed diploe, has open fontanelles and an incompletely developed styloid process.

• A. Ethmoid Bone
• B. Tongue
• C. Sphenoid
• D. A and B

Explanation: The foramen caecum is found at the junction of the frontal and ethmoid regions of the skull and is also the small pit on the dorsum of the…

• A. Pterion
• B. Obelion
• C. Asterion
• D. Bregma

Explanation: The asterion is the palpable junction of the parietomastoid, occipitomastoid and lambdoid sutures.
