What is the anatomy of the forearm?

The forearm is the lower part of the arm, which is located between the elbow and the wrist. There are 20 muscles under the skin and fat just below the skin: eight on the side of the palm and 12 on the back. The supply of these muscles is several main arteries and nerves, namely Ulnar artery and medium and ulnar nerves in the front and radial artery and radial nerve in the rear compartment. The deepest structures in the forearms are two long bones, radius and ulna. The elbow, which connects the peaks of the radius and the ulna and the lower part of the humerus at the top of the arm, is the type of synovial joint known as Golamium or Hinge joint. Possible joint movements are flexion and extension or bending and straightening elbow.

The wrist is a connection between the radius and the carpal bones of the hand. It can produce Flexion and extension movements, as well as adction and kidnapping, or waving your hand from side to side. Between the wrist and the elbow are two more joints, the proximal and distal radioul joints, which are the place where the radius and ulna meet their upperH and lower ends and which allow the forearm to be rotated.

There are eight muscles in the front of the forearms, all of them are on the palms of the arm. These muscles are usually responsible for bending or ripple in hand and fingers, as well as for pronation, turn the arm down. They include five superficial muscles, Flexor Carpi Radialis, Palmaris Longus, Flexor Carpi Ulnaris, Pronator Teres and Flexor Digitorum Superfialis and three deep muscles, Flexor Digitorum Pundus, Flexor Pollicis Longus and Pronator Quadratus.

The rear partition of the forearm includes 12 muscles that are largely involved in the movements of the extension or straightening of the wrist and fingers and turning the arm. They include four superficial, two medium and six deep muscles. Brachioradialis, extensor carpi radialis longus, extensor carpi radialis brevis and extensor carpi ulnaris are in a superficial compartment. Extensor Digitorum and Extensor Digiti mini are in medium comparisTMENT. Abductor Pollicis Longus, extensor pollicis brevis, extensor pollicis longus, extensor indis, supinator and anconeus are in deep compartment.

Delivery of these muscles The necessary nutrients and innervation is to create movement and respond to external stimuli is several blood vessels and nerves. The front and rear compartments of the forearms are distinguished from each other not by the place of muscles and tendons contained inside, but by blood vessels and nerves pervading. In the front, the main artery of the Ulnar artery, so named because it runs on the middle or Ulnar side of the arm, the side of the pinky finger.

The main nerves of this section are the central nerve that runs down in the middle of the arm and enters the hand through the carpal tunnel in the wrist and Ulnar Nerv, which innerizes Ulnar side of the arm. In the back of the section, the blood is received from the radial artery, which is located along the side or radial side of the arm. The main nerve is the radial nerve, which is located along the same side of the arm, thumb.
