Origin

The meningeal branch of the maxillary nerve is the first branch of the maxillary nerve. It is given off just proximal to the foramen rotundum, while still intracranial.

Course

From its origin, the meningeal branch of the maxillary nerve runs laterally a very short distance to the foramen spinosum. Here it finds and follows the middle meningeal artery as this artery ascends and spreads throughout the dura of the middle cranial fossa.

Branches

There are no named branches.

Supplied Structures

The meningeal branch of the maxillary nerve is a sensory nerve that conveys general sensation from the dura of the middle cranial fossa. Its territory is roughly the same as that of the middle meningeal artery.
