This muscle (if you have it, not everyone does) is a long and narrow muscle that runs from the elbow to the wrist. It is believed it may have been an important muscle for hanging and climbing.
Wonder if this has any bearing on what seperates the great from the good. Any thoughts??

From memory it's involved in abduction of the fifth (little) finger, and if it's not there (11% of arms don't have it) another tendon performs the same action. Maybe with less strength? Saunders'd be the one to ask.

Palmaris longus?
From memory it attaches to the palmar aponeurosis (the connective tissue under the palm/skin of the hand) and its action is flexing the wrist, but I don't think it is a strong flexor?
Would be interesting to hear from Dr Saunders...
Can we still call him Dr in NSW?
Do this to see if you have it:

Though sometimes your flexor digi longus will look like this during this test too.
(abduction of the little finger is normally by abductor digiti minimi)

Yeah, I think you're right about action and insertion. I didn't pay enough attention in anatomy tutes. (Biochem was a different story - tutor's name was, appropriately, Aphrodite) I'd imagine it could have a small influence on wrist flexion strength.

Ha!
I think my Biochem lecturer took tonal enounciation lessons from Steven Hawkings.
Shit, those lectures were painful.

The anatomy AP lecturing us 1st years (back then) believed in Creationism. And having read my last post, I didn't mean my biochem tutor could have an influence on wrist strength, I meant the tendon. I guess I could just reach for a textbook... but no.

when i was in the UK i was involved in a study about this Palmaris Muscle (as a test subject) but i found out that it was used to keep the palm of our hands skin tight when we were swinging through trees so they didn't tear. And as a species we are slowly evolving to loose this muscle. the researchers came to one of the gyms i trained at and found that climbers were no more likely to have it or not compared to the general population and that it had no effect on how hard you climbed, so can't use that one as an excuse, sorry. That least this is what i can remember from quite a while ago.

Very interesting. Thanks for the info.
