Common interosseous aery is a branch of -

Branches of ulnar aeryA) In cubital fossa1) Anterior ulnar recurrent :- Anastomoses with inferior ulnar collateral in from of medial epicondyle.2) Posterior ulnar recurrent :- Anastomoses with superior ulnar collateral behind medial cpicondyle.3) Common interosseous :- Divides intoi) Anterior interosseous : It is the deepest aery of front of forearm. It is accompanied by anterior interosseous nerve (a branch of median nerve). It pierces interosseous membrane at upper border of pronator quadratus to enter into extensor (dorsal) compament. Its branches are : (a) muscular branches for deep muscles of front of forearm; (b) nutrient aery to radius and ulna; and (c) median aery.ii) Posterior interosseous : Near its origin, it gives of interosseous recurrent aery which ends by anastomosing with middle collateral aery.B) In forearm1) Palmar carpal branch2) Dorsal carpal branchC) In palm :- These are terminal branches.i) Deep branch :- Completes the deep palmar arch on medial side by joining the terminal pa of radial aery.ii) Superficial branch :- Forms the major pa of superficial palmar arch.
