The rete mirabile of the maxillary artery was studied in the cat by means of the acryl plastic injection method. Four afferent arterial vessels of the rete were investigated as follows: the lateral retial branches arising from the posterior deep temporal and the inferior alveolar arteries outside the rete, the medial retial branches arising from the middle meningeal and the maxillary arteries, the anterior retial branches arising from the buccal, the anterior deep temporal and the zygomatic arteries, and the intraretial branches arising from the maxillary artery within the rete. The lateral retial branch was similar in its course to the maxillary artery in the crab-eating monkey and man. An arterial circle was formed by the lateral retial branch, the maxillary artery and the posterior part of the rete, and contained the lateral pterygoid muscle and the mandibular nerve. In the formation of the rete, its deep portion around the maxillary artery and nerve was formed by the intraretial branches, its superficial portion by the other afferent vessels, and the intermediate portion by rich anastomoses between both portions. Eight efferent arterial vessels were observed as follows: the external ethmoidal, the meningeal, the extraocular muscular, the lacrimal, a communicating branch with the external ethmoidal, the temporal branch, the interretial artery (which was proper in the cat)and the anastomotic artery (rr. retis of Nomina anatomies veterinaria 1973) which was formed by a confluence of the component branches of the rete. The anastomotic artery played a significant role in the blood supply to the brain, after receiving the anastomotic ramus originating from the middlle meningeal artery instead of the degenerated and obturated remnant of the internal carotid artery.
