Internal spermatic arteries Internal spermatic arteries are visceral paired arteries. In the male, these arteries arise from the ventral face of the aorta close together near the posterior mesenteric artery. Each very slender and is the longest branch. It is at first directed downwards, backwards and outwards reaches the internal inguinal canal as one of the […]
Lumbar arteries are parietal paired arteries. These arise in series with aortic intercostal arteries and are similar in origin and distribution. There are 6 pairs of lumbar arteries. Of which, the first arise from the aorta and sixth arises from the internal iliac artery. They arises from the dorsal face of the aorta, pass across
Renal artery is a visceral paired artery. these are right and left arises close together from the inferior face of the abdominal aorta about 8 cm behind the origin of the preceding branch. The right renal artery is shorter but larger while the left renal artery is longer but narrow. The right artery enters the
Anterior mesenteric artery is a Visceral unpaired artery. It arises from the ventral face of the abdominal aorta immediately behind the coeliac artery and is of the same size. Its lateral faces are related to the anterior mesenteric ganglia and the mesenteric plexus encloses the artery. Collateral branches of Anterior mesenteric artery Pancreatic branches to
Coeliac artery is a Visceral unpaired artery. This arises from the ventral face of the abdominal aorta as it enters the abdominal cavity. The coeliac ganglia are on the lateral face of the artery and the coeliac plexus enclose the artery along its course. It is about 7 to 9 cm long runs downwards on
The branches of the abdominal aorta are intended to supply the abdominal walls and the organs in the abdominal cavity. Some of them supply to the spinal cord and its meninges, some to the pelvic walls and organs and some to the spermatic cords and scrotum. Two of its branches, the external iliac arteries are
Dorsal metacarpal artery is very small vessel (often absent), which arises from the rete carpi dorsale. It passes down the dorsal metacarpal groove and below the fetlock it is joined by the distal perforating metacarpal artery from the deep volar arch to form the volar common digital artery. This receives a communicating branch from the
The Ulnar artery of the brachial artery is the larger of the two terminal branches of the median artery. It descends under the flexor carpi radialis, passes through the carpal canal on the medial face of tendon of the deep flexor and is continued as the volar common digital artery. This vessel passes superficially underneath
The radial artery is the smaller of the two terminal branches of the median artery. It descends along the medio-volar border of the radius under the flexor carpi radialis, passes down subcutaneously over the posterior aspect of the carpus under the deep fascia but out side the carpal canal and is continued down as the
The Median artery of the brachial artery is the continuation of the brachial artery below the level of the medial condyle of the Humerus. It passes along the posteromedial face of the radius and divides at variable distances down the forearm into radial and ulnar arteries. Collateral branches of Median artery A long muscular branch
