26
Q

In the Cubital Fossa the Brachial A. branches into what?

A

Ulnar A.

Radial A.

A

Common Interosseous A.

28
Q

What does the Common Interosseous A. branch into?

A

Anterior Interosseous A.
Posterior Interosseous A.

***These two meet to form the Dorsal Carpal Arch

29
Q

This branches off the Posterior Interosseous A. and travels superiorly behind the Lateral Epicondyle where it anastomoses with the Middle Collateral A.

A

Interosseous Recurrent A.

30
Q

The Ulnar A. and Radial A. meet in the wrist to form what?

A

Feed into Palmar Carpal Branches which form the Palmar Carpal Arch

31
Q

The Ulnar A. and Radial A. also travel dorsally at the wrist to form what?

A

Feed into Dorsal Carpal Branchs which form the Dorsal Carpal Arch

***Anterior and Posterior Interosseous As. also feed into the Dorsal Carpal Arch

32
Q

These arteries branch off the Dorsal Carpal Arch and form an anastomosis with the Perforating Branches from the Deep Palmar Arch then produce Dorsal Digital As.

A

Dorsal Metacarpal A.

33
Q

These arteries are formed by Dorsal Metacarpal A. and Perforating branches from the Deep Palmar Arch.

A

Dorsal Digital A.

34
Q

A

Palmar Branch of the Radial A.

36
Q

What arteries branch off the Superficial Palmar Arch?

38
Q

The Deep Palmar Arch divides into what?
