Nerve Interosseous Posterior Forearm

The interosseous nerve of the posterior forearm is one of the most important nerves in the forearm region, which is responsible for innervation of the muscles, tendons and skin on the back of the forearm. It is a continuation of the median nerve and passes through the interosseous membrane, which separates the two bones of the forearm: the ulna and the radius.

The interosseous nerve of the posterior forearm begins from the median nerve in the carpal tunnel, then passes through the interosseous space between the ulna and radius bones and ends in the posterior part of the forearm at the base of the elbow joint.

The innervation of the muscles and tendons on the posterior surface of the forearm is carried out through nerve endings that are located in the skin and muscles. The interosseous nerve of the posterior forearm is also involved in the innervation of the skin on the dorsum of the forearm and fingers.

Injury to the interosseous posterior forearm nerve can result in loss of sensation and motor function in the dorsum of the forearm and fingers, as well as loss of control of the muscles innervated by this nerve.

To prevent injury to the interosseous posterior forearm nerve, care must be taken when performing exercises that involve stretching and straining the muscles in the posterior forearm, and avoid injury or damage to this area.

Unpleasant sensations in the area of ​​the forearms occur in a person for various reasons: pain appears after a blow, a sprain, or an awkward position of the arm. In such cases, a pathology called **interosseous nerve** (Latin name n. interossei) helps to understand the problem. Essentially it is a group of six nerve fibers. Neurons **nn. interosseous antebrachii medialis et lateralis**.

All “nerves” are divided into anterior and posterior sections. The latter may appear together, forming dichotia of the intermuscular nerve. It is worth noting that topographic anatomy can make its own adjustments to this fact. This nerve takes part in the innervation of joints and skin in the proximal forearm
