Palmaris longus muscle

<p>The palmaris longus is a <a href="/facts/Muscle/dmxrL8pH">muscle</a> visible as a small <a href="/facts/Tendon/M0Kdf7Fy">tendon</a> located between the <a href="/facts/Flexor_carpi_radialis/zfppja2G">flexor carpi radialis</a> and the <a href="/facts/Flexor_carpi_ulnaris/UI7bH9pH">flexor carpi ulnaris</a>, although it is not always present. Reviews report rates of absence in the general population ranging from 10–20%; however, the rate varies in different ethnic groups. Absence of the palmaris longus does not have an effect on grip strength. The lack of palmaris longus muscle does result in decreased pinch strength in fourth and fifth fingers. The absence of palmaris longus muscle is more prevalent in females than males.
</p><p>The palmaris longus muscle can be observed by touching the pads of the <a href="/facts/Ring_finger/DY1PehDn">fourth finger</a> and <a href="/facts/Thumb/vx1ycnbA">thumb</a> and flexing the wrist. The tendon, if present, will be visible in the midline of the anterior wrist.
