Extension of the forearm at the elbow joint is achieved almost entirely by the triceps brachii but extension of the arm, which actually takes place at the shoulder joint, is achieved by muscles on the back, such as the latissimus dorsi.
The supinator muscle is a muscle in the forearm that is not directly responsible for flexion or extension of the arm. Its primary function is to rotate the forearm in a movement called supination, where the palm faces up.
The muscles that produce extension of the finger joints and wrist are the extensor muscles. In the forearm, the specific extensor muscles responsible for extension of the fingers and wrist include the extensor digitorum and extensor carpi radialis muscles.
The flexor digitorum superficialis muscle in the forearm is roughly the size of your fist. It is responsible for flexing the fingers.
The extension in the elbow occurs when the triceps muscle contracts, causing the forearm to straighten out. This movement is essential when performing actions like pushing and lifting objects.
In the lateral side of the forearm, you can find the radius bone, as well as the muscles responsible for wrist extension and thumb movement. The radial artery also runs along the lateral side of the forearm.

The anterior forearm muscle does not actually exist. Instead, there are a total of eight different muscles with the anterior compartment of the forearm. Their jobs are specifically related to flexion and pronation, or inward rotation of the hand.
One muscle that starts with the letter "U" is the Ulnaris muscle, also known as the Extensor carpi ulnaris. It is located in the forearm and is responsible for wrist extension and adduction.

The muscles that produce extension of the finger joints and wrist are the extensor muscles. In the forearm, the specific extensor muscles responsible for extension of the fingers and wrist include the extensor digitorum and extensor carpi radialis muscles.
The flexor carpi radialis is the agonist muscle in wrist flexion. This muscle, know as a wrist flexor, is located in the forearm.
There are about 20 muscles in a forearm, consisting of flexors and extensors. Flexors are responsible for flexing the forearm, wrist, and fingers.
The flexor digitorum superficialis muscle in the forearm is roughly the size of your fist. It is responsible for flexing the fingers.
The extension in the elbow occurs when the triceps muscle contracts, causing the forearm to straighten out. This movement is essential when performing actions like pushing and lifting objects.
In the lateral side of the forearm, you can find the radius bone, as well as the muscles responsible for wrist extension and thumb movement. The radial artery also runs along the lateral side of the forearm.
The muscle responsible for pulling the forearm toward you while rowing is primarily the latissimus dorsi. This large muscle, located in the back, plays a crucial role in arm movement, particularly in adduction and extension. Additionally, the biceps brachii also assists in flexing the elbow during the rowing motion. Together, these muscles contribute to the powerful pulling action needed in rowing.
Biceps are a muscle, not a tissue. The biceps brachii muscle is located in the upper arm and is responsible for flexing the elbow and rotating the forearm.
