It is one of the muscles of the anterior compartment of the forearm and is notable for its variability in the human population.<br /> <br /> === Anatomy ===<br /> The Palmaris longus muscle originates from the [[medial epicondyle of the humerus]] via the common flexor tendon. It runs distally and inserts into the [[palmar aponeurosis]] and the flexor retinaculum of the hand. The muscle is innervated by the [[median nerve]].<br /> <br /> === Function ===<br /> The primary function of the Palmaris longus muscle is to tense the palmar aponeurosis, which helps in gripping objects. It also assists in flexing the hand at the wrist joint.<br /> <br /> === Variability ===<br /> The Palmaris longus muscle is absent in about 14% of the population, with variations occurring bilaterally or unilaterally. The absence of this muscle does not typically result in any functional deficit.<br /> <br /> === Clinical Significance ===<br /> The Palmaris longus muscle is often used as a donor tendon for various reconstructive surgical procedures due to its expendability. It is commonly harvested for tendon grafts in surgeries such as [[Tommy John surgery]] and [[ligament reconstruction]].<br /> <br /> === Related Structures ===<br /> * [[Flexor carpi radialis muscle]]<br /> * [[Flexor carpi ulnaris muscle]]<br /> * [[Flexor digitorum superficialis muscle]]<br /> * [[Flexor digitorum profundus muscle]]<br /> * [[Flexor pollicis longus muscle]]<br /> <br /> === See Also ===<br /> * [[Forearm muscles]]<br /> * [[Median nerve]]<br /> * [[Palmar aponeurosis]]<br /> * [[Flexor retinaculum of the hand]]<br /> <br /> == References ==<br /> {{Reflist}}<br /> <br /> == External Links ==<br /> {{Commons category|Palmaris longus muscles}}<br /> <br /> [[Category:Muscles of the upper limb]]<br /> [[Category:Anatomy]]<br /> [[Category:Musculoskeletal system]]<br /> <br /> {{Anatomy-stub}}</div>
