The maxillary artery passes through which anatomical opening?
Show answer and explanation
Correct answer: A. Pterygomaxillary fissure
✓ A) Pterygomaxillary fissure is correct.
The maxillary artery (terminal branch of the external carotid) passes through the pterygomaxillary fissure to enter the pterygopalatine fossa, where it gives off the posterior superior alveolar, infraorbital, and descending palatine arteries. Foramen ovale transmits CN V3 (mandibular nerve) and accessory meningeal artery. Foramen rotundum transmits CN V2 (maxillary nerve). The pterygomaxillary fissure is the anatomical gateway between the infratemporal and pterygopalatine fossae.
