some tendon in the middle of your wrist, visible when you touch pinky to thumb.  may "help climbing"

I've got both!   
now just need to start climbing 8C...

I need more than two tendons to help with my climbing 

[Muenchener]

My peroneus longus tendon sits on top of my ankle bone rather than behind it - a physio once told me he had never seen that before.

[Nibile]

I think I'm missing both...

Abstract

The palmaris longus tendon is the most frequently harvested tendon for reconstructive plastic and hand surgical procedures. A question patients often ask is whether loss of the palmaris longus will result in any functional deficit. In order to answer this question, the presence or absence of the palmaris longus muscle was clinically determined in 418 normal Asian subjects. All subjects also had their grip and pinch strengths measured. No statistically significant difference was seen in the grip or pinch strength measurements between subjects who had a palmaris longus tendon and those who did not. This study demonstrates that absence of the palmaris longus is not associated with a decrease of grip or pinch strength.

Feel any better?

So what does it do then, or is it like your appendix or a dew claw?

The PL attaches distally to the skin of palm and flexes the wrist. It will not influence finger strength but could be the crucial difference in hanging slopers. Mine are present in both hands so I need to be more imaginative in my excuses.

It probably is an evolutionary relic. Our ancestors would have used it fridge-hugging up trees when escaping from sabre-tooth tigers.
