FDP is shown in blue. The flexor digitorum profundus or flexor digitorum communis profundus[1] is a muscle in the forearm of humans that flexes the fingers (also known as digits). It is considered an extrinsic hand muscle because it acts on the hand while its muscle belly is located in the forearm. Together the flexor pollicis longus, pronator ...

Flexor carpi ulnaris muscle. Dorsal (left) and ventral (right) views of deep muscles of the left forearm. The flexor carpi ulnaris muscle is in blue. The flexor carpi ulnaris (FCU) is a muscle of the forearm that flexes and adducts at the wrist joint.
In the case of fingers and toes, it is bringing the digits together, towards the centerline of the hand or foot. Dropping the arms to the sides, and bringing the knees together, are examples of adduction. [15] Adduction of the wrist is also known as ulnar deviation which moves the hand towards the ulnar styloid (or, towards the little finger).
The flexor digitorum longus muscle is responsible for the movement and curling of the second, third, fourth and fifth toes. This muscle makes it possible for the toes to grip the surface of floors, which is important when it comes to maintaining postural balance on surfaces that are rough or uneven. The other deep muscles are the flexor ...
Skeletal muscle. Skeletal muscle, or "voluntary muscle", is a striated muscle tissue that primarily joins to bone with tendons. Skeletal muscle enables movement of bones, and maintains posture. [ 1 ] The widest part of a muscle that pulls on the tendons is known as the belly.
The flexor carpi radialis is one of four muscles in the superficial layer of the anterior compartment of the forearm. This muscle originates from the medial epicondyle of the humerus as part of the common flexor tendon. It runs just laterally of flexor digitorum superficialis and inserts on the anterior aspect of the base of the second ...
Anatomical terms of muscle. [ edit on Wikidata] The lumbricals are intrinsic muscles of the hand that flex the metacarpophalangeal joints, [ 1 ] and extend the interphalangeal joints. [ 1 ][ 2 ] The lumbrical muscles of the foot also have a similar action, though they are of less clinical concern.
