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 ...

The flexor digitorum longus muscle or flexor digitorum communis longus[ 1 ] is situated on the tibial side of the leg. At its origin it is thin and pointed, but it gradually increases in size as it descends. It serves to flex the second, third, fourth, and fifth toes.
The muscles of the hand are the skeletal muscles responsible for the movement of the hand and fingers. The muscles of the hand can be subdivided into two groups: the extrinsic and intrinsic muscle groups. The extrinsic muscle groups are the long flexors and extensors. They are called extrinsic because the muscle belly is located on the forearm.
The direction of terms are opposite to those in the foot because of embryological rotation of the limbs in opposite directions. [10] Palmarflexion is flexion of the wrist towards the palm and ventral side of forearm. [30] Dorsiflexion is hyperextension of the wrist joint, towards the dorsal side of forearm. [30]
Transverse section across distal ends of radius and ulna. (Flexor dig. subliminis labeled at center top.) Flexor digitorum superficialis (flexor digitorum sublimis) or flexor digitorum communis sublimis[1] is an extrinsic flexor muscle of the fingers at the proximal interphalangeal joints. It is in the anterior compartment of the forearm.
The flexor pollicis longus (/ ˈ f l ɛ k s ər ˈ p ɒ l ɪ s ɪ s ˈ l ɒ ŋ ɡ ə s /; FPL, Latin flexor, bender; pollicis, of the thumb; longus, long) is a muscle in the forearm and hand that flexes the thumb. It lies in the same plane as the flexor digitorum profundus. This muscle is unique to humans, being either rudimentary or absent in ...
The pronator teres is a muscle (located mainly in the forearm) that, along with the Pronator quadratus muscle pronator quadratus, serves to pronate the forearm (turning it so that the palm faces posteriorly when from the anatomical position). It has two origins, at the medial humeral supracondylar ridge and the medial side of the coronoid ...
