Flexor digitorum sublimis

From WikiMD's Wellnesspedia

Flexor Digitorum Sublimis is a muscle in the anterior compartment of forearm that is involved in the flexion of the fingers. It is one of the three flexor muscles, the other two being the Flexor Digitorum Profundus and the Flexor Pollicis Longus.

Anatomy[edit | edit source]

The Flexor Digitorum Sublimis originates from the medial epicondyle of the humerus, the coronoid process of the ulna, and the shaft of the radius. It inserts into the middle phalanges of the four fingers. The muscle is innervated by the median nerve.

Function[edit | edit source]

The primary function of the Flexor Digitorum Sublimis is to flex the fingers. It also assists in flexing the wrist.

Clinical Significance[edit | edit source]

Damage to the Flexor Digitorum Sublimis can result in a loss of ability to flex the fingers, which can significantly impact hand function. Conditions such as carpal tunnel syndrome can compress the median nerve, affecting the function of this muscle.
