• A. Ethmoid
• B. Sphenoid
• C. Nasal
• D. Mandible

Explanation: The sphenoid is often described as resembling a bat with outstretched wings because of its broad greater and lesser wings.

• A. Accessory meningeal artery
• B. Middle meningeal artery
• C. Mandibular nerve

Explanation: The middle meningeal artery enters the cranial cavity through the foramen spinosum.

• A. Nasal
• B. Lacrimal

• A. 18
• B. 20
• C. 22
• D. 40

Explanation: An adult skull has 22 bones: 8 cranial bones and 14 facial bones. This count excludes the auditory ossicles and hyoid bone.

• A. Maxilla and the sphenoid bone
• B. Sphenoid and the ethmoid bone
• C. Sphenoid and the vomer
• D. None of the above

Explanation: The palatine bone lies between the maxilla anteriorly and the sphenoid posteriorly, helping connect these bones.

• A. Between roots of premolars
• B. Between roots of molars
• C. Near canine
• D. Between Incisions

Explanation: The mental foramen usually opens on the body of the mandible below or between the roots of the premolar teeth.

• A. Genial tubercle
• B. Mylohyoid ridge
• C. Lingula
• D. Mental foramen

Explanation: The mental foramen is on the external, lateral surface of the mandible, not its internal surface.

• A. Frontal
• B. Zygomatic
• C. Palatine
• D. Temporal

Explanation: The maxilla articulates with the frontal, zygomatic, and palatine bones, among others. It does not articulate with the temporal bone.

• 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.
