The flexor digitorum longus (FDL) is part of the deep muscle group of the posterior compartment of the lower leg [1]. Its primary action is flexion of digits 2-5 in the foot. Origin. Medial portion of the posterior surface of the tibia, inferior to the soleal line. It is also connected to the fibula by a broad tendon [1].
Jan 3, 2022 · Summary. Flexor digitorum longus. Origin. Posterior surface of tibia distal to popliteal line. Insertion. Splits into four slips after passing through medial intermuscular septum of plantar surface of foot; these slips then insert on plantar surface of bases of 2nd - 5th distal phalanges. Action.

- Tibial nerve (S2, S3)
Jul 24, 2023 · The intermediate group includes the flexor digitorum superficialis. This muscle is innervated by the median nerve and allows for flexion of the wrist, MCP, and PIP joints of digits 2-5. The deep group includes the flexor digitorum profundus and flexor pollicis longus. The flexor digitorum profundus has a mixed innervation.

Attachments: Originates from the medial surface of the tibia and attaches to the plantar surfaces of the lateral four digits. Actions: Flexion of the lateral four toes.
Aug 14, 2023 · The flexor pollicis longus muscle inserts on the thumb at the distal phalanx. The flexor digitorum profundus muscle originates from the proximal end of the radius and ulnar.
