Buccal mucosa, nasal cavity and maxilla is innervated by:
- A.
Maxillary branch
- B.
Ophthalmic branch
- C.
Mandibular branch
- D.
Ophthalmic and Mandibular branch
Correct Answer
A. Maxillary branchExplanation
The buccal mucosa, nasal cavity, and maxilla are innervated by the maxillary branch. This branch is one of the three main branches of the trigeminal nerve, which is responsible for sensory innervation of the face. The maxillary branch specifically supplies sensation to the upper jaw, teeth, nasal cavity, and the mucous membrane of the cheek and upper lip. It does not innervate the ophthalmic branch or the mandibular branch, which supply sensation to different areas of the face.Rate this question:

Division 2 of CN V is running from:
- A.
Foramen Rotundum
- B.
Superior orbital fissure
- C.
Foramen Ovale
- D.
Inferior orbital fissure
Correct Answer
A. Foramen RotundumExplanation
Division 2 of CN V, also known as the maxillary nerve, runs from the foramen rotundum. The foramen rotundum is a small opening in the sphenoid bone located in the middle cranial fossa. This opening allows the maxillary nerve to exit the skull and enter the pterygopalatine fossa, where it gives off various branches to innervate the upper teeth, the maxillary sinus, and the palate. Therefore, the correct answer is Foramen Rotundum.Rate this question:

Division 3 of CN V is running from:
- A.
Foramen Ovale
- B.
Superior orbital fissure
- C.
Foramen Rotundum
- D.
Inferior orbital fissure
Correct Answer
A. Foramen OvaleExplanation
Division 3 of CN V, also known as the mandibular division, runs from the foramen ovale. The foramen ovale is an oval-shaped opening located in the greater wing of the sphenoid bone. It serves as a passageway for the mandibular nerve, which is the largest branch of CN V. This division of the trigeminal nerve is responsible for providing sensory innervation to the lower jaw, lower teeth, and the muscles involved in chewing.Rate this question:
