Abdominal aorta

The aorta, after having passed the diaphragm is thus named. It rests on the bodies of the vertebras, extending from the front of the last dorsal to the fourth lumbar vertebra, a little to the left of the median line, where it usually divides. The anterior surface of the great artery is successively in apposition with the liver, the splenic vein, the pancreas, the third portion of the duodenum, the left renal vein, and the peritoneum. The vena cava lies at its right side, the right crus of the diaphragm being interposed at the upper part of the abdomen ; close to the same side, are the thoracic duct and the azygos vein, which are placed between the aorta and the right crus of the diaphragm. The aorta is surrounded by a mesh of nerves derived from the sympathetic.

The abdominal aorta, [aorta abdominalis, French : aorte abdominale], gives numerous branches, which may be divided into two sets, viz., those which supply the viscera and and those which are distributed to the walls of the abdomen. The former consist of the coeliac artery, the superior mesenteric , the inferieur mesenteric, the capsular, the renal, and the spermatic arteries ; which among the latter are included the phrenic, the lumbar, and the middle sacral arteries. The first three of the visceral branches are single arteries.  

Anatomical description of the superior mesenteric artery

Hits: 2889

The superior mesenteric artery (french : artère mésentérique supérieure) arises from the anterior surface of the aorta, on the middle line, at 2 cm below the origin of the coeliac artery, nearly at the level of the disc between the second and third lumbar, vertebras.

Circumflex iliac artery

Details
Hits: 1938

The circumflex iliac artery [Latin : circumflexa ilii], smaller than the preceding vessel, arises from the outer side of the iliac artery near Poupart's ligament, and is directed outwards behind that structure to the anterior superior spine of the ilium.

Coronary artery of the stomach.

Hits: 1583

The coronary artery of the stomach (coronaria ventriculi ; French : coronaire stomachique), the smallest of the three visceral branches derived from the coeliac artery, inclines upwards, and to the left side, to reach the cardiac orifice of the stomach.

Coeliac artery or axis

Details
Hits: 1556

The coeliac artery, [a. coeliaca, French : tronc cœliaque] , a short and very thick vessel, arises from the aorta close to the margin of the diaphragm. In the erect position of the body its direction is nearly horizontal forwards, and it is not more than half an inch long.

Femoral artery

Hits: 1073

The femoral artery (femoralis s. cruralis ; French: artère fémorale ), is that portion of the artery of the lower limb which lies along the upper two-thirds of the thigh, — its limits being marked, above, by Poupart's ligament, and below, by the opening in the great adductor muscle, after passing through which the artery assumes the name popliteal.

Branches of the deep femoral artery

The external circumflex artery, [circumfiexa femoris interna s. posterior,] a branch of considerable size, arises from the outer side of the profunda, and, after passing outwards for a short distance beneath the sartorius and rectus muscles, and through the divisions of the anterior crural nerve, gives branches, which may be divided into three sets, according to the directions which they take.

The peculiarities of this artery relate to its origin, its course, its size, and the condition of its branches.

Dorsal artery of the foot

Details
Hits: 1031

The dorsal artery of the foot (a. dorsalis pedis), the continuation of the anterior tibial artery, extends from the termination of that vessel at the bend of the ankle, to the posterior end of the first metatarsal space, where it divides into two branches, of which one proceeds forwards in the first interosseous space, whilst the other dips into the sole of the foot, and terminates by inosculating with the plantar arch. This vessel, in its course forwards, rests upon the astragalus, the scaphoid, and internal cuneiform bones and their respective articulations. It lies in the interval between the tendon of the proper extensor of the great toe, and that of the long extensor of the other toes ; and is covered by (besides the integument) the fascia of the foot, and by a layer of dense cellular membrane, which binds it to the parts beneath. Near its end, it is crossed by the innermost tendon of the short extensor of the toes.
