Anatomical study on branches of external carotid artery in one humped camel [camelus dromedarius] and comparing it with ruminants and equine

ABSTRACT

The branches of external carotid artery were dissected and studied in six one humped camels.These specimens were preparated from slaughterhouse and fixed in10% formaline. The common carotid artery in one humped camel is divided into three branches, including, occipital artery, internal carotid artery and external carotid artery which in this respect it was similar to that of equine. External carotid artery was the main branch of common carotid artery. Lingual artery in one humped camel was similar to that of the small ruminants and separated from external carotid artery. External carotid artery under the temporomandibular joint was divided into two branches ; the maxillary and superficial temporal arteries. In one humped camel similar to that of the small ruminants, transverse facial artery was separated from the superficial temporal artery and was the major source of blood supply to the facial region. Direction and the course of this artery in camal was slightly different from that of the small ruminants. Maxillary artery had an extraosseous position in one humped camel. There was only one rete branch in camel,similar to rostral rete branches of the ruminants. The branch entered through the orbitorotundum foramen to form extradural rete mirabile
