Extensor Muscles Of The Forearm. Anatomically, the muscles in this compartment can be divided. The muscles in the posterior compartment of the forearm are commonly known as the extensor muscles.
The muscles in the posterior compartment of the forearm are commonly known as the extensor muscles.
They control movements of the wrist, hand, fingers and thumb.
The extensor carpi radialis longus is one of the five main muscles that control movements at the wrist. Anatomically, the muscles in this compartment can be divided. The general function of these muscles is to produce extension at the wrist and fingers. Your wrist extensors are also important in sports for movements such as tennis backhand. The hand motion of sprinting requires rapid flexion of the elbow and your brachioradialis and brachialis will assist with this. The superficial extensors of the forearm are the brachioradialis, extensor carpi radialis longus, anconeus, extensor carpi radialis brevis The extrinsic hand muscles originate in the forearm and insert on structures within the hand.
The hand motion of sprinting requires rapid flexion of the elbow and your brachioradialis and brachialis will assist with this. They are all innervated by the radial nerve. The general function of these muscles is to produce extension at the wrist and fingers. The image is meant for indication only, and I recommend you search for a more detailed anatomical diagram for a more accurate placement. Your wrist extensors are also important in sports for movements such as tennis backhand. The muscle fibers then descend towards the wrist area where they converge onto a narrow tendon.
