Following foramina are found in greater wing of sphenoid except:
**Core Concept**
The greater wing of the sphenoid bone is a significant anatomical landmark in the skull base, containing multiple foramina that permit the passage of nerves, vessels, and other structures. These foramina play a crucial role in various cranial nerves and blood vessels.
**Why the Correct Answer is Right**
The greater wing of the sphenoid bone houses several foramina, including the foramen ovale, foramen spinosum, and foramen rotundum. These foramina are essential for the transmission of the mandibular division of the trigeminal nerve (V3), the middle meningeal artery, and the maxillary nerve (V2), respectively. The foramen ovale is a significant passage for the mandibular nerve, which carries motor fibers to the muscles of mastication, while the foramen spinosum transmits the middle meningeal artery, which supplies the dura mater. The foramen rotundum allows the passage of the maxillary nerve, which is responsible for the sensory innervation of the face.
