Primitive maxillary artery

Initially, at early embryonic stages, the ventral and dorsal aortas communicate by a certain number of arterial bridges, the aortic arches (1 to 4 in the craniocaudal direction). Other embryonic arteries are the primitive maxillary artery, dorsal ophthalmic artery, ventral ophthalmic artery, anterior cerebral artery and the longitudinal neural arteries (Fig. 18.1). 

Embryologically, the dorsal ophthalmic artery, the stapedial artery, the trigeminal artery and the primitive maxillary artery are involved in this anastomosis.
