 What muscle defines the portions of the subclavian artery? | The scalene anterior. |
| What are the branches of the 1st portion of the subclavian artery? | The vertebral artery, the inferior thoracic artery, and the thyrocervical trunk which branches into the: inferior thyroid artery (which gives off the ascending cervical artery), the suprascapular artery, and the transverse cervical artery, which branches into the superficial cervical artery, and sometimes, the dorsal scapular artery. |
| What are the branches of the 2nd portion of the subclavian artery? | The costocervical trunk, which gives off branches to the supreme intercoastal artery and deep cervical artery. |
| What is sometimes found on the 3rd portion of the subclavian artery? | The dorsal scapular artery. |
| What four arteries converge to form the anastemosis on the dorsal scapula? | The suprascapular artery, the dorsal scapular artery, and the circumflex subscapular artery. |
| What structure marks the boundary between the subclavian and axillary artery? | The lateral portion of the 1st rib. |
| What muscle divides the axillary artery into 3 equal portions? | The pectoralis minor. |
| What branches off the axillary artery in its 1st portion? | The superior thoracic artery. |
| What branches off the axillary artery in its 2nd portion? | The lateral thoracic artery, and the thoracoacromial trunk, which branches into the acromial artery, deltoid artery, clavicular artery, and pectoral artery. |
| What branches off the axillary artery in its 3rd portion? | The anterior circumflex humeral artery, the posterior circumflex humeral artery, and the subscapular artery, which branches into: the circumflex subscapular artery and the thoracodorsal artery. |
| What branches off of the brachial artery? | The superior ulnar collateral artery, the inferior ulnar collateral artery, and the brachial profundus (Deep) artery, which branches into the radial collateral artery and middle collateral artery. |
| What artery forms an anastemosis with the radial collateral artery? | The radial recurrent artery. |
| What artery forms an anastemosis with the middle collateral artery? | The posterior interosseus recurrent artery. |
| What artery forms an anastemosis with the superior ulnar collateral artery? | The posterior ulnar recurrent artery. |
| What artery forms an anastemosis with the inferior ulnar collateral artery? | The anterior ulnar recurrent artery. |
| What branches of the radial artery form arches in or near the hand? | The palmar carpal branch, the dorsal carpal branch, the superficial palmar branch, and the deep palmar branch. |
| Name the three palmar arches of the hand from proximal to distal. | The palmar carpal branch, the deep palmar branch, and the superficial palmar branch. |
| Which artery provides a fuller supply of blood to the deep palmar arch, the radial or ulnar? | The radial. |
| Which artery provides a larger blood supply to the superficial palmar arch, the radial or ulnar? | The ulnar. |
| What is the only branch of the radial artery not related to the hand? | The radial recurrent artery. |
| What branches does the deep palmar branch of the radial artery give off? | The dorsallis pollicis artery, the dorsallis indices artery, the princeps pollices artery, the radialis indices artery, 3 palmar metacarpal arteries, 2 perforating arteries, and the first dorsal metacarpal artery which supplies both the thumb and index finger. |
| What branches does the ulnar artery give off that are unrelated to the hand? | The anterior ulnar recurrent artery, the posterior ulnar recurrent artery, and the common interosseus artery, which branches into the anterior interosseus artery and posterior interosseus artery, which gives off the posterior interosseus recurrent artery. |
| What branches off of the dorsal carpal arch? | 3 dorsal metacarpal arteries, and the dorsal digital arteries. |
| What branches off of the superficial palmar branch of the ulnar artery? | 4 palmar digital arteries, which come together with the metacarpal and perforating arteries of the radial artery to form the 4 proper palmar digital arteries. |
| What are all the branches of the ulnar artery? | The anterior/posterior ulnar recurrent arteries, the common interosseus artery: the posterior interosseus recurrent, the anterior/ posterior interosseus arteries, the palmar carpal branch, the dorsal carpal branch, the deep palmar branch, the superficial branch, the common palmar digital arteries, and the proper palmar digital arteries. |
| What are all the branches of the radial artery? | The radial recurrent artery, the palmar carpal branch, the dorsal carpal branch, the superficial palmar branch, the deep palmar branch: the dorsallis pollicis artery, the dorsallis indices artery, the princeps pollices artery, the radialis indices artery, 3 palmar metacarpal arteries, 2 perforating arteries, and the 1st dorsal metacarpal artery. |
| What exception is there to the blood vessels lateral symmetry? | Because the heart is located to the left, the heart gives off an extra shunt called the brachiocephalic trunk to the right side of the body. The subclavian artery comes off the trunk at the sternoclavicular joint. |
| How can the subclavian artery become impinged? | The scalene can compress the artery, the clavical can depress the artery, and a surgical rib can depress the artery. |
| How does the suprascapular artery travel through the suprascapular notch. | The artery travels over the transverse scapular ligament. |
| Where are most deep veins found? | Next to their respective arteries. One or two veins to every artery. |
| What are the two primary superficial veins? | Cephalic Vein, and Basilic Vein. |
| What is the course of the cephalic vein? | Begins at distal radial forearm, travels up the anteriolateral forearm, the anteriolateral brachium, travels between biceps and deltoid, dumps into the axillary vein in the deltopectoral triangle, travels through the subclavian vein, and then the superior vena cava. |
| What is the course of the basilic vein? | Begins in the distal dorsal medial forearm, travels anteriomedial up the antebrachium, follows the biceps, at the mid-humeral level dives deep and enters an anastemosis with the brachial vein, to the axillary vein, subclavian vein, and superior vena cava. |
| What is the vein in the middle of the anterior forearm? | The anterior intermediate vein, or anterior median vein. |
| What is the course of the anterior intermediate vein? | Travels from the mid forearm upwards, and splits at the cubital fossa to the cephalic, and basillic vein. In another variation, the intermediate vein joins the basilic, and a median cubital vein. |
| Do deep or superficial veins bring more blood back to the heart? | The superficial veins. |
| What are the two lymphatic ducts, and which receives more material? | The thoracic duct receives more material than the right lymphatic duct. |
| What areas of the body drain to the right lymphatic duct? | The lateral head, thorax, arm, and hand. |
| Which artery contributes more to the dorsal carpal arch, the ulnar or radial artery? | The radial artery. |
