Morphological Configuration of the Brain Arterial Supply of the Goat (Capra hircus)

The anatomical study of the brain arteries is of great clinical and prognostic value. Because of veterinary practitioners have limited information about the intracranial circulation. Therefore, the present study aimed to configure course and variability of the arteries supplying the brain in goat. The study used eight goat heads to establishing the morphological pattern of the brain arteries. In goat, the internal carotid artery ill-developed supracranial but its intracranial reconstructed from the rete mirabile that formed from the maxillary artery at the cavernous sinus of dura mater. Our study recorded the brain received its blood through the maxillary and basilar arteries. The internal carotid artery leaved rete mirabile and divided into the rostral cerebral and caudal communicating arteries. The rostral cerebral artery formed the rostral part of the arterial circle of the brain while the caudal communicating arteries formed the caudal part. The rostral cerebral artery branched the rostral choroid artery, the artery of corpus callosum and bifurcated into the internal ophthalmic and internal ethmoidal arteries. The caudal communicating artery branched the caudal cerebral artery. The descend pattern of some arteries in all studied brains was asymmetric. The rostral cerebellar artery originated by double branches from the caudal communicating artery. The left caudal cerebellar artery was double while the right one was single.
