antebrachial flexor muscles, and the elbow joint.

25
Q

A. transverse cubiti supplies the..?arises on..? passing beneath..?

A

This laterally directed vessel arises on the flexion surface of the elbow. It supplies the extensor muscles of the carpus and digits by passing beneath the distal biceps and brachialis muscles; it also supplies the elbow joint

26
Q

A. brachialis superficialis arises from ..? and can also from..? and were it arises?

A

While this branch usually arises from the A. brachialis, it can also arise from the A. bicipitalis. The vessel arises proximal to the elbow joint;

27
Q

who continues as the A. antebrachialis superficialis cranialis? and were?

A

Distal to the elbow, the A. brachialis superficialis continues as the A. antebrachialis superficialis cranialis

28
Q

after receiving the A.collateralis radialis, it runs cranio-distally over the distal M. biceps brachii. it is..?

A

A. brachialis superficialis

29
Q

A. antebrachialis superficialis cranialis divides into..?both branches run..?on witch M..?and accompany the R…?

A

This artery immediately divides into medial and lateral branches. Both branches run distally on the M. extensor carpi radialis and accompany the corresponding branches of the radial nerve’s R. superficialis

30
Q

A. interossea communis is the last branch of..?
arises from..?
on the deep surface of the..?
runs to..?

A

This laterally directed artery is the last branch of the A. brachialis. It arises distal to the elbow joint, on the deep surface of the M. pronator teres, and runs to the proximal interosseous space.

31
Q

A. interossea communis giving rise to..?

A

After giving rise to the A. ulnaris (usually), it divides to form the A. interossea cranialis and A. interossea caudalis.

32
Q

A. ulnaris This artery usually arises from the..? but can also arise from..?

A. mediana is main source of blood to..?occasionally also gives rise to the..?

A

it is the main source of blood to the Manus. In addition to the following branches, the A. mediana occasionally also gives rise to the ulnar artery.

41
Q

The median artery runs..?

A

The median artery runs distally on the caudo-medial border of the radius, covered by the M. flexor carpi radialis. Proximal to the carpus, it runs in the groove (medially) between the deep and superficial digital flexor tendons. It then runs through the carpal canal and branches on the palmar surface of the metacarpus to form the superficial palmar arterial system

Q

Distal to the origin of the….. the brachial artery continues as the A. mediana

A

Distal to the origin of the A. interossea communis, the brachial artery continues as the A.
mediana

43
Q

A. profunda antebrachii This artery usually arises from the..?sometimes arises from the?

A

This artery usually arises from the proximal segment of the A. mediana. However, it
sometimes arises from the distal part of the A. brachialis or from the A. interossea communis; it
may also occur as more than one artery.

44
Q

A. profunda antebrachii runs..?anastomoses with the..?

45
Q

A. radialis arises from the..?It runs..?
