The maxillary artery exits the infratemporal fossa through which structure?

  1. Pterygomaxillary fissure
  2. Foramen ovale
  3. Foramen spinosum
  4. Infraorbital foramen
Show answer and explanation

Correct answer: A. Pterygomaxillary fissure

The maxillary artery is the larger terminal branch of the external carotid artery. It has three parts: mandibular, pterygoid, and pterygopalatine. The artery passes through the pterygomaxillary fissure (also called the pterygopalatine fissure) to enter the pterygopalatine fossa, where it gives off its terminal branches including the posterior superior alveolar artery, infraorbital artery, greater palatine artery, and sphenopalatine artery. The foramen ovale and foramen spinosum transmit CN V3 and the middle meningeal artery respectively, and are intracranial structures. The infraorbital foramen is where the infraorbital nerve exits, not the maxillary artery.
