Nerves Digital Palmar Proper

The palmar digital nerves (nervi digitales palmares proprii) are a group of nerves that run from the base of the thumb to the base of the little finger on the back of the hand. These nerves innervate the skin and muscles on the palmar side of the fingers and palm, and also provide sensory information about touch and pressure on this area.

The digital palmar own nerves are divided into two types: digital palmar nerves and digital palmar branches. The digital palmar nerves (nervi digitalis palmis) begin from the medial fascicle of the brachial plexus and pass to the base of the thumb. They then divide into two branches: the first dorsal branch (ramus dorsalis) and the second palmar branch (ramus palmaris). The first branch goes to the skin and muscles of the thumb, and the second branch branches into small nerve endings that innervate the skin on the lateral surfaces of the remaining fingers and palms.

The digital palmar branches (rami digitales volares) begin from the lateral bundle of the brachial plexus. They go to the bases of the remaining fingers, where they branch into small nerve endings. These nerve endings innervate the skin and muscle tissue on the palmar surface of the fingers and the bases of the nails.

The functions of the digital palmar nerves include control of movement of the fingers and hands, as well as sensory innervation of the skin of the palms and fingers. Impaired function of these nerves can lead to loss of sensation and movement in the area, as well as pain and discomfort.

Diagnosis and treatment of digital palmar nerve dysfunction may include physical therapy, massage, stretching and muscle strengthening exercises. In some cases, surgery may be necessary to repair the nerve or remove scar tissue that may limit movement and sensation.

Palmar digital nerves (nervi digitales palmaris proprii; lat. nervus - nerve; digitus, digitus palmae - finger; proprius - own) - thin, consisting of myelinated and unmyelinated fibers of the branch of the median nerve (see Median nerve), located at the base of the fingers .

**Number**. The palmar nerve emerges from the middle part of the roots of the median (bone) nerve in the main structure. In the interosseous space between the bones of the forearm, it bends around the ulnar interosseous nerve and artery, lies to the dorsum of the internal interosseous muscle, descends along it, passes along the bottom of the deep groove between the muscles of the eminence of the thumb and returns to the ulnar edge of the forearm. At the wrist joint, the nerve divides into the medial and lateral digital nerves, respectively, resting on the inner surface of the tendon of the long flexor pollicis. Each nerve ends on the palmar side of the finger with several fan-shaped branches diverging to the sides, thin nerve fibers and very small sensitive epithelial endings that contribute to the sensitivity of the skin of the dorsal and palmar surfaces of the fingertips in the joint area, as well as the skin of the fingers in the projection area of ​​the palmar and plantar interfascial surfaces and fascia of the forearm (lateral surface).

Functions. When transmitting motor impulses, nerve fibers ensure the functioning of the large and index interosseous muscles, which ensure the opposition of the thumb to the rest. Sensitive functions
