Muscle Palmar Longus

The palmar muscles of a person allow him to firmly hold and quickly move objects in space. One of them is the palmar longus muscle (PL). It takes part in flexion of the hand and its movement towards the elbow joint. By contracting, this muscle helps relieve the load on the flexors, which bend the fingers and prevent them from rotating and deviating from the vertical axis when lifting weights and holding an object in the hand.

The palmar DC is enclosed between the tendons of two other muscles: the supinator, located posteriorly, and the flexor digitorum superficialis (FDS), located nearby inwardly. In the middle, the muscle is partially covered by the palmar oblique muscle, which prevents it from being closed by the fingers when the arm is flexed. It is located in the carpal tunnel in the form of an anatomical tract that stretches from the metacarpus to the fingertips.

It originates from the four bellies of the first and second fingers of the hand and attaches to the bases of the joints and ligaments of the third, fourth and fifth fingers. The deep transverse aponeurosis of the fascia of the long DC located underneath gives rise to the SFP tendons, which are attached to the base of the middle phalanx of the first finger. If the DC is injured or paralyzed, this may cause pain in the palm and hand.



The palmar longus muscle (lat. m. palmaris) is one of the muscles of the hand that takes part in flexing the phalanges of the fingers. It is located in the front of the hand and occupies half the length of its back side. Another name for the muscle is the longus pollicis muscle.

The muscle begins on the anterior surface of the dorsum of the radius with a semilunar notch, and ends on the first articular phalanx of the thumb. The rectus muscle is connected to each other by the tendons of all thumbs on the hand. Both ends of the muscle are attached to the second and third phalanges of the thumb.

The interweaving of muscles in the palm forms tough tendons that connect the fingers to the hand, called digital ligaments. These bundles



The muscles of the hand are the most important part of the human musculoskeletal system. Proper tone of these muscles ensures that the hand can grasp objects correctly to perform various activities. By performing various exercises, the hand muscles can develop strength, which is very important for people involved in sports.

The palmaris longus muscle (m.palmarislongus) is a flat and fusiform pronator. lies behind the metacarpophalangeal joints, begins on the lower third of the base of the fifth metacarpal bone and from the posterior edge of the calcaneus. Attaches to the lateral surface of the radius. Function: opposes the thumb to all other fingers. Also, when this muscle contracts
