What muscle extend and adduct ?
Extensor carpi ulnaris
What muscle extend and abduct ?
Extensor carpi radialus
What is the function of extensor retinaculum ?

Axillary
What is the guide of ulnar nerve and artery ?
Tendon of flexor carpi ulnaris
what is the exception of brachioradialus ?
It’s innervated by radial nerve however radial nerve only innervates extensor muscles and brachioradialis is a flexor muscle
What nerve is injured in tennis elbow ?
