Select and explain. 
A. Foramen rotundum, B. Foramen spinosum, C. Foramen ovale, D. Jugular foramen

Answer: B: Foramen spinosum 
Explanation: The middle meningeal aery is a branch of the first pa of the maxillary aery, given off in the infratemporal fossa. In infratemporal fossa, the aery runs upwards and medially deep to the lateral pterygoid muscle and superficial to the sphenomandibular ligament. Here it passes through a loop formed by the two roots of the auriculotemporal nerve. It enters the middle cranial fossa through foramen spinosum. Notes: Middle meningeal aery is impoant to the surgeon because this aery is the commonest source of extradural hemorrhage. Ref BDC volume 3,6th edition pg 201
