Oct 10, 2018 · Scientists have found that, while palmaris longus is present in many species of mammals today, it's most developed in those that use their forearms to move around - such as lemurs and monkeys. Here's another one: have you figured out how to manipulate the three muscles around the base of your ear so you can wriggle it ever-so-slightly?
We hypothesize that evolution is currently underway in the human forearm, as demonstrated by four muscles that are in the midst of evolutionary change or have recently evolved to their current presentation. These four muscles are: (a) FDS-V, (b) anconeus, (c) palmaris longus, and (d) AE.

Nov 3, 2023 · Palmaris longus is the most superficial muscle of the superficial forearm flexors, found deep to the forearm skin. It sits between the flexor carpi radialis and flexor carpi ulnaris muscles, superficial to the flexor digitorum superficialis muscle.

Apr 12, 2013 · In both sexes, the palmaris longus muscle increased pinch strength in the fourth and fifth fingers of the hands (especially in the right hand). Based on these findings, we have concluded that the palmaris longus muscle may impact the opposition movement of the fingers.

Feb 17, 2015 · A review of the literature and data novel to this study illustrate that different populations of humans exhibit remarkable variation in the frequency of palmaris longus agenesis, from less than 5% of Chinese to nearly 65% of Indians.

Does palmaris longus have a long tendon?
Does the palmaris longus muscle affect the opposition movement of the fingers?
The palmaris longus is one of the most variable muscles of the human body. An understanding of its variations is useful as it is often used as a tendon graft and for tendon transfer. We report another interesting variation in its anatomy.
