Lateral Thoracic Vein
The lateral thoracic vein (sometimes debatably referred to as the long thoracic vein) is a tributary of the axillary vein. It runs with the lateral thoracic artery and drains the serratus anterior muscle and the pectoralis major muscle. Normally, the thoracoepigastric vein exists between this vein and superficial epigastric vein (a tributary of femoral vein In the human body, the femoral vein is the vein that accompanies the femoral artery in the femoral sheath. It is a deep vein that begins at the adductor hiatus (an opening in the adductor magnus muscle) as the continuation of the popliteal v ...), to act as a shunt for blood if the portal system (through the liver) develops hypertension or a blockage.

Axillary Vein
In human anatomy, the axillary vein is a large blood vessel that conveys blood from the lateral aspect of the thorax, axilla (armpit) and upper limb toward the heart. There is one axillary vein on each side of the body. Structure Its origin is at the lower margin of the teres major muscle and a continuation of the brachial vein. This large vein is formed by the brachial vein and the basilic vein. At its terminal part, it is also joined by the cephalic vein. Other tributaries include the subscapular vein, circumflex humeral vein, lateral thoracic vein and thoraco-acromial vein. It terminates at the lateral margin of the first rib, at which it becomes the subclavian vein. It is accompanied along its course by a similarly named artery, the axillary artery In human anatomy, the axillary artery is a large blood vessel that conveys oxygenated blood to the lateral aspect of the thorax, the axilla (armpit) and the upper limb.

Lateral Thoracic Artery
In the human body, the lateral thoracic artery (or external mammary artery) is a blood vessel that supplies oxygenated blood to approximately one-third of the lateral structures of the thorax and breast. It originates from the axillary artery and follows the lower border of the pectoralis minor muscle to the side of the chest to supply the serratus anterior muscle, pectoralis major muscle and pectoralis minor muscle, and sends branches across the axilla to the axillary lymph nodes and subscapularis muscle. It anastomoses with the internal thoracic artery, subscapular, and intercostal arteries, and with the pectoral branch of the thoracoacromial artery. In the female it supplies an external mammary branch which turns round the free edge of the pectoralis major and supplies the breasts. Variations Variations in the Axillary Artery are quite common. Differences in its origin, course, branching pattern, and size may cause variations in the number or arrangement of branches ...

Serratus Anterior Muscle
The serratus anterior is a muscle of the chest. It originates at the side of the chest from the upper 8 or 9 ribs; it inserts along the entire length of the anterior aspect of the medial border of the scapula. It is innervated by the long thoracic nerve from the brachial plexus. The serratus anterior acts to pull the scapula forward around the thorax. The muscle is named from Latin: ''serrare'' = to saw (referring to the shape); and ''anterior'' = on the front side of the body. Structure Origin Serratus anterior normally originates by nine or ten muscle slips – arising from either the 1st to 8th ribs, or the 1st to 9th ribs; because two slips usually arise from the 2nd rib, the number of slips is greater than the number of ribs from which they originate. Insertion The muscle is inserted along the medial border of the scapula between the superior and inferior angle of the scapula. The muscle is divided into three parts according to the points of insertion: * the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thoracoepigastric Vein
The thoracoepigastric vein runs along the lateral aspect of the trunk between the superficial epigastric vein below and the lateral thoracic vein above and establishes an important communication between the femoral vein and axillary vein. This is an especially important vein when the inferior vena cava (IVC) becomes obstructed, by providing a means of collateral venous return. It creates a cavocaval anastomosis by connecting with superficial epigastric veins arising from femoral vein just below inguinal ligament. Clinical significance The thoracoepigastric vein is unique in that it drains to both the superior vena cava (SVC) and to the inferior vena cava (IVC). Hence, it serves as an anastomotic caval-caval link between the two. Furthermore, the thoracoepigastric vein is connected to the portal vein via the paraumbilical vein and thereby serves as a portocaval anastomosis as well. When a patient experiences portal hypertension, there can be congestion (backup) of blood that ente ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Femoral Vein
In the human body, the femoral vein is the vein that accompanies the femoral artery in the femoral sheath. It is a deep vein that begins at the adductor hiatus (an opening in the adductor magnus muscle) as the continuation of the popliteal vein. The great saphenous vein (a superficial vein), and the deep femoral vein drain into the femoral vein in the femoral triangle when it becomes known as the common femoral vein. It ends at the inferior margin of the inguinal ligament where it becomes the external iliac vein. Its major tributaries are the deep femoral vein, and the great saphenous vein. The femoral vein contains valves. Structure The femoral vein bears valves which are mostly bicuspid and whose number is variable between individuals and often between left and right leg. Course The femoral vein continues into the thigh as the continuation from the popliteal vein at the back of the knee. It drains blood from the deep thigh muscles and thigh bone. Proximal to th ...
