Unit 1 Venous Anatomy of the Upper Extremity Kyle Thornton DMI 63 Unit 1 Venous Anatomy of the Upper Extremity Kyle Thornton

The Main Veins of the Upper Extremity Two sets of veins in the upper extremity Superficial Digital – posterior surface of phalanx Metacarpal – posterior surface of hand Cephalic – radial side of the anterior forearm Basilic – medial side of the anterior forearm Median Antecubital – anterior antecubital fossa Deep Radial – lateral side of the forearm Ulnar – medial side of the forearm Brachial – medial side of the humerus Axillary Subclavian

Superficial and Deep Veins Superficial veins Deep veins http://www.pitt.edu/~anat/Extremities/UpperExt/UpperExt.htm

Characteristics of Veins Thin-walled structures Many veins contain valves to maintain unidirectional flow of blood Less elasticity than arteries Larger lumen than arteries Lower pressure flow than arteries Most veins carry deoxygenated blood Cross section of a vein showing a valve that prevents backflow Venous valves prevent reverse blood flow

Circulation from Peripheral Veins to Heart

Review Name the two large superficial veins of the forearm Name the two large deep veins of the forearm Name the superficial vein that courses diagonally between the cephalic basilic Name two characteristics in which veins differ from arteries List the path in which blood flow courses from a peripheral vein to the heart
