Anterior Humeral Circumflex Artery
The anterior humeral circumflex artery (anterior circumflex artery, anterior circumflex humeral artery) is an artery in the arm. It is one of two circumflexing arteries that branch from the axillary artery, the other being the posterior humeral circumflex artery. The anterior humeral circumflex artery is considerably smaller than the posterior and arises nearly opposite to it, from the lateral side of the axillary artery. The anterior humeral circumflex artery runs horizontally, beneath the coracobrachialis and short head of the biceps brachii muscle, in front of the neck of the humerus. On reaching the intertubercular sulcus, it gives off a branch which ascends in the sulcus to supply the head of the humerus and the shoulder-joint. The trunk of the vessel is then continued onward beneath the long head of the biceps brachii and the deltoideus muscle, and anastomoses with the posterior humeral circumflex artery.

Circumflex Branch Of Left Coronary Artery
The circumflex branch of left coronary artery, or left circumflex artery or circumflex artery, is a branch of the left coronary artery. Description The left circumflex artery follows the left part of the coronary sulcus, running first to the left and then to the right, reaching nearly as far as the posterior longitudinal sulcus. There have been multiple anomalies described, for example the left circumflex having an aberrant course from the right coronary artery. Branches The circumflex artery curves to the left around the heart within the coronary sulcus, giving rise to one or more left marginal arteries (also called obtuse marginal branches) as it curves toward the posterior surface of the heart. It helps form the posterior left ''ventricular branch'' or posterolateral artery. The circumflex artery ends at the point where it joins to form to the posterior interventricular artery in 15% of all cases, which lies in the posterior interventricular sulcus. In the other 85% of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circumflex Fibular Artery
The circumflex fibular artery (circumflex fibular branch, circumflex branch of posterior tibial artery, or circumflex peroneal branch of posterior tibial artery) is a branch of the posterior tibial artery which supplies blood to the knee. The artery branch of the anterior tibial artery, at its initial (or superior) segment, winds around the neck of the fibula and joins patellar network The patellar network (circulatory anastomosis around the knee-joint, patellar anastomosis, genicular anastomosis, articular vascular network of knee or rete articulare genushttp://medical-dictionary.thefreedictionary.com/rete+articulare+genus) i ....

Circumflex Scapular Artery
The circumflex scapular artery (scapular circumflex artery, dorsalis scapulae artery) is a branch of the subscapular artery and part of the scapular anastomoses. It curves around the axillary border of the scapula, traveling through the anatomical " Triangular space" made up of the Teres minor superiorly, the Teres major inferiorly, and the long head of the Triceps laterally. It enters the infraspinatous fossa under cover of the Teres minor, and anastomoses with the transverse scapular artery (suprascapular) and the descending branch of the transverse cervical (a.k.a. dorsal scapular artery). Branches In its course it gives off two branches: * one (infrascapular) enters the subscapular fossa beneath the Subscapularis, which it supplies, anastomosing with the transverse scapular artery and the descending branch of the transverse cervical. * the other is continued along the axillary border of the scapula, between the Teres major and minor, and at the dorsal surface of th ...

Deep Circumflex Iliac Artery
The deep circumflex iliac artery (or deep iliac circumflex artery) is an artery in the pelvis that travels along the iliac crest of the pelvic bone. Course The deep circumflex iliac artery arises from the lateral aspect of the external iliac artery nearly opposite the origin of the inferior epigastric artery. It ascends obliquely and laterally, posterior to the inguinal ligament, contained in a fibrous sheath formed by the junction of the transversalis fascia and iliac fascia. It travels to the anterior superior iliac spine, where it anastomoses with the ascending branch of the lateral femoral circumflex artery. It then pierces the transversalis fascia and passes medially along the inner lip of the crest of the ilium to a point where it perforates the transversus abdominis muscle. From there, it travels posteriorly between the transversus abdominis muscle and the internal oblique muscle to anastomose with the iliolumbar artery and the superior gluteal artery. Opposite the ...

Lateral Circumflex Femoral Artery
The lateral circumflex femoral artery, also known as the lateral femoral circumflex artery, or the external circumflex artery, is an artery in the upper thigh. It is usually a branch of the profunda femoris artery, and produces three branches. It is mostly distributed to the muscles of the lateral thigh. Structure Origin The lateral femoral circumflex artery usually arises from the lateral side of the profunda femoris artery, but may occasionally arise directly from the femoral artery. It is the largest branch of the profunda femoris artery. Course and relations The lateral circumflex femoral artery usually courses anterior to the femoral neck. It passes horizontally between the divisions of the femoral nerve. It passes posterior to the sartorius muscle and rectus femoris muscle. It passes laterally across the hip joint capsule. It divides into ascending, transverse, and descending branches. Branches The lateral circumflex femoral artery has three branches: # The ascending ...

Medial Circumflex Femoral Artery
The medial circumflex femoral artery (internal circumflex artery, medial femoral circumflex artery) is an artery in the upper thigh that arises from the profunda femoris artery''.'' Damage to the artery following a femoral neck fracture may lead to avascular necrosis (ischemic) of the femoral neck/head. Structure Origin The medial femoral circumflex artery arises from the posterior medial aspect of the profunda femoris artery''.'' The medial femoral circumflex artery may occasionally arise directly from the femoral artery. Course and relations It winds around the medial side of the femur, passing first between the pectineus and iliopsoas muscles, and then between the obturator externus and the adductor brevis muscles. Branches At the upper border of the adductor brevis it gives off two branches: * The '' ascending branch'' * The ''descending branch'' descends beneath the adductor brevis, to supply it and the adductor magnus; the continuation of the vessel passes backwar ...

Posterior Humeral Circumflex Artery
The posterior humeral circumflex artery (posterior circumflex artery, posterior circumflex humeral artery) arises from the third part of axillary artery at the lower border of the subscapularis, and runs posteriorly with the axillary nerve through the quadrangular space. It winds around the surgical neck of the humerus and is distributed to the deltoid muscle and shoulder-joint, anastomosing with the anterior humeral circumflex and deep artery of the arm. It supplies the teres major, teres minor, deltoid, and (long head only) triceps muscles. Additional images File:Gray810.png, Suprascapular and axillary nerves of right side, seen from behind.
