The palmaris longus is seen as a small tendon between the flexor carpi radialis and the flexor carpi ulnaris although it is not always present. The muscle is absent in about 14 percent of the population however this number varies greatly in African Asian and Native American populations. Absence of this muscle does not have an effect on grip strength; however lack of the palmaris longus muscle is disadvantageous in that its tendon cannot be harvested as a graft if necessary.
