Question

Match List-I with List-II

List-I (Foramen)	List-II (Transmitted structures)
(A) Maxillary Foramen	(I) Internal Maxillary artery
(B) Oval Foramen	(II) Mandibular nerve
(C) Supraorbital Foramen	(III) Frontal nerve and vessels
(D) Alar Foramen	(IV) Infraorbital nerve and vessels

• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (IV), (C) - (III), (D) - (II)
• (A) - (IV), (B) - (II), (C) - (III), (D) - (I)
• (A) - (IV), (B) - (I), (C) - (III), (D) - (II)

Hint:

- Foramen Ovale = Mandibular nerve (V3).
- Maxillary Foramen = Cranial entrance to infraorbital canal.
- Alar Canal = Internal Maxillary artery.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
The skull features numerous foramina (holes or canals) that allow the passage of cranial nerves, blood vessels, and other vital structures between the cranial cavity and the external surfaces of the head.

Step 2: Detailed Explanation:
Let us match the foramina in List I with the corresponding structures they transmit in List II:
- (A) Maxillary Foramen:
The maxillary foramen is located in the pterygopalatine fossa.
It marks the cranial entrance of the infraorbital canal, transmitting the infraorbital nerve (a branch of the maxillary division of the trigeminal nerve) and the infraorbital artery and vein.
Thus, (A) matches with (IV).
- (B) Oval Foramen (Foramen ovale):
The oval foramen is located in the sphenoid bone at the base of the skull.
It transmits the mandibular nerve (the third division of the trigeminal nerve, CN V3).
Thus, (B) matches with (II).
- (C) Supraorbital Foramen:
This foramen is located in the frontal bone near the dorsal margin of the orbit.
It transmits the frontal (or supraorbital) nerve and associated ophthalmic vessels, supplying the forehead skin and frontal sinus region.
Thus, (C) matches with (III).
- (D) Alar Foramen:
The alar canal (via the caudal and cranial alar foramina) is located in the sphenoid bone.
It transmits the internal maxillary artery (a major branch of the external carotid artery) as it passes towards the pterygopalatine fossa.
Thus, (D) matches with (I).
Combining these matches, we get: (A)-(IV), (B)-(II), (C)-(III), (D)-(I).

Step 3: Final Answer:
The correct option is (C).
