4. How is the arterial supply of the anterior compartment?

Inf. border of teres major

Axillary artery Till where?

Brachial artery

Neck of the radius Bracihal artery divides intoUlnar artery (medial)Radial artery (lateral)

5. Which veins do you see in the anterior compartment?(Paired) Deep veins accompanying veins plentiful in the forearm.arise from the anastomosing deep venous palmar arch in the hand.

drain into brachial veins in the cubital fossa.

6. ...the median nerve in the anterior compartment?principal nerveno branches in the arm other than small twigs to the brachial artery. Its major branch in the forearm anterior interosseous nerve

Leaves the cubital fossa by passing between 2 heads of the pronator teres and humero-ulnar and radial heads of the flexor digitorum superficialis.

7. ...the ulnar nerve in the anterior compartment?

Enters the anterior compartment by passing posteriorly around medial epicondyle of humerus and between humeral and ulnar heads of flexor carpi ulnaris muscle

Two small cutaneous branches; palmar branch & dorsal branch

8. ....the radial nerve in the anterior compartment?motor and sensory functions in both arm & forearm (but only sensory functions in the hand) in the forearm Superficial (sensory)deep to brachioradialis deep (motor)between two heads of supinator

9. What are the boundaries of the cubital fossa?Superiorly imaginary line connecting medial &lateral epicondyles.Medially pronator teres.Laterally brachioradialis.

10. ...the contents of the cubital fossa?

1) Terminal part of the brachial artery,radial and ulnar arteries 2) Biceps brachii tendon

3) Median nerve

4) Radial nerve

5) (Deep) accompanying veins of the arteries

11...the contents of the cubital fossa?

Superficially, in the subcutaneous tissue overlying the fossa median cubital vein, medial and lateral antebrachial cutaneous nervesbasilic and cephalic veins.

12. ....nerves in the cubital fossa?

median nerve lies immediately medial to the brachial artery and leaves the fossa by passing between the ulnar and humeral heads of the pronator teres muscle.

radial nerve lies under brachioradialis (lateral margin of the fossa)

gives off deep branch of the radial nerve and continues as superficial radial nerve.
