Digital veins Dorsal venous arch Cephalic vein Basilic vein Median cubital vein Median veins of forearm (Median cephalic vein) (Median basilic vein)

Origin: Lateral side of dorsal venous arch of the hand Path: Ascends the lateral forearm, through the cubital fossa, up the lateral arm, into the deltopectoral groove, and then the infraclavicular fossa. Termination: Drains into the axillary vein after piercing the clavipectoral fascia.

Origin: Medial side of the dorsal venous arch of the hand. Path: Ascends the medial forearm, through the cubital fossa, up the medial arm Termination: Pierces the deep fascia in the mid-arm and joins the brachial veins, forming the axillary vein.

Connects cephalic and basilic veins in the cubital fossa (the bend of your elbow) Common site for drawing blood or administering intravenous fluids

used for venipuncture, transfusions, and cardiac catheterization

Located near the radial styloid process. * In the deltopectoral triangle, it can connect to the external jugular vein. Clavicle fractures can damage this connection, leading to hematomas.

Separated from the brachial artery by the bicipital aponeurosis. This separation protects the artery during injections. Common site for venipuncture

Superficial lymph vessels drain upwards to the axilla

Lymph follows the cephalic vein to the infraclavicular lymph nodes

Lymph follows the basilic vein to the lateral group of axillary lymph nodes

Lymph from muscles and deep structures drains directly into the lateral group of axillary lymph nodes.

Infection of lymph vessels, common in the arm Characterized by red streaks along the affected vessels. Lymph from the thumb and index finger drain from cephalic vein to the infraclavicular axillary nodes. Lymph from the other fingers and medial hand drain from basilic vein to the supratrochlear node, then to the lateral axillary nodes

Infection reaching the lymph nodes. Causes enlarged and tender lymph nodes.
