The forearm contains two long bones, the radius and the ulna. These bones are connected by the interosseous membrane. Ultimately, the forearm is covered by skin, the anterior surface usually being less hairy than the posterior surface. Grays illustration of a human femur, a typically recognized bone. ... The radius and ulna of the left forearm, posterior surface. ... The ulna (along with the radius) is one of the two bones in the forearm. ...

The forearm contains many muscles, including the flexors and extensors of the digits, a flexor of the elbow (brachioradialis), and pronators and supinators that turn the hand to face upwards or down. Brachioradialis is a muscle located in the forearm, that acts to flex the elbow. ...

In cross-section the forearm can be divided into two fascial compartments. The posterior compartment contains the extensors of the hands, which are supplied by the radial nerve. On the human body, the limbs can be divide into segments, such as the arm and the forearm of the upper limb, and the thigh and the leg of the lower limb. ... The radial nerve is a nerve in the human body, that supplies the arm, the forearm and the hand. ...

The anterior compartment contains the flexors, and is mainly supplied by the median nerve. The ulnar nerve also runs the length of the forearm. The median nerve is a nerve that runs down the arm and forearm. ... The ulnar nerve is a nerve that in humans runs down the arm and forearm, and into the hand. ...

The radial and ulnar arteries, and their branches, supply the blood to the forearm. These usually run on the anterior face of the radius and ulna down the whole forearm. The radial artery is the main blood vessel, with oxygenated blood, of the lateral aspect of the forearm. ...

The main superficial veins of the forearm are the cephalic vein, the median antebrachial and the basilic vein. These veins can be used for cannularisation or venipuncture, although the cubital fossa is a preferred site for getting blood. This vein is located in the superficial fascia along the anterolateral surface of the biceps brachii muscle and is often visible through the skin. ... Venipuncture (also known as phlebotomy or simply bleeding) is the process of obtaining blood from someone, from one of their veins. ... The cubital fossa is the area of the arm in front of the elbow joint. ...

Firearms

In firearms, the forearm is a section of the weapon between the receiver and the muzzle. It is used to hold the firearm steady and is usually made out of wood or composite material. A firearm is a kinetic energy weapon that fires either a single or multiple projectiles propelled at high velocity by the gases produced by action of the rapid confined burning of a propellant. ... In firearms terminology, the receiver is the part of the firearm that houses the operating parts of the gun. ... The muzzle of a firearm is the end of the barrel from which the projectile will exit. ...
