It's my understanding that the brachioradialis aids only in flexion, not extension. There are two muscles, the extensor digitorum and the extensor carpi ulnaris, that aid in the extending of the elbow. The extension of the elbow by these two muscles appears only to come after extension of the fingers and/or the wrist. At best, I think these muscles are subordinate to the actions of the triceps brachii and the anconeus. Discounting the roles of the triceps brachii and the anconeus in the extending of the elbow requires intoxication. Ted, I was only addressing the middle portion of Jeff's post: "Forerarm muscles can only perform the following anatomical actions-: 1) Flex, extend, abduct or adduct the fingers and thumb. 2) Palmarflex or dorsiflex the wrist. 3) Radially deviate or ulnarly deviate the wrist. 4) Pronate or supinate the hand. Forearm muscles cannot flex or extend the elbow joint because they are distal (peripheral) to the elbow joint. Jeff." Hopefully, that makes my post more relevant. The point is that some "forearm" muscles are able to flex the forearm and some forearm muscles are able to extend the forearm. Those are the muscles that cross the elbow joint. I wasn't posting to the degree of relevance or Bucket's drinking habits, all I was pointing out since Jeff asked was that his limited definition was not correct. Not all forearm muscles have tendon attachments that are distal to the elbow joint, as you correctly pointed out in your post with the addition of some extensor forearm muscles. __________________ Life Goal- Developing a new theory of movement based on Brain Science Interests - Dabbling with insanity Hobbies- Creating Quality Last edited by Mike O : 11-24-2008 at 09:18 PM.
