Hi viewers!
Welcome Back to Doctor Speaks!
This is a tutorial on the anatomy of deep muscles of posterior compartment of forearm. The deep muscles of posterior forearm include supinator, abductor pollicis longus, extensor pollicis longus, extensor pollicis brevis and extensor indicis muscle. Unlike the superficial muscles of this compartment, these muscles does not have a common origin but they do have one thing in common and that's these muscles receive their innervation from the deep branch of radial nerve just like the superficial extensors of forearm.
So this tutorial explains the important anatomical features of these muscles.
Thank You.
