Digitorum muscle

The digitorum muscles of the human hand, from Gray's Anatomy.

The Digitorum Muscle is a group of muscles in the human body that are primarily responsible for flexion of the fingers or toes. These muscles are found in both the hand and the foot, and are named for their function: "digitorum" is Latin for "of the fingers".

Anatomy

The digitorum muscles are divided into two main groups: the Flexor Digitorum Superficialis and the Flexor Digitorum Profundus. The superficialis muscles are located in the forearm and control the movement of the middle and distal phalanges, while the profundus muscles control the movement of the distal phalanges.

The flexor digitorum profundus and superficialis.

Function

The primary function of the digitorum muscles is to allow for flexion of the fingers and toes. This is essential for many everyday tasks, such as gripping objects, typing, and walking. In addition, these muscles also play a role in the rotation of the wrist and the extension of the fingers and toes.

Clinical Significance

Damage or injury to the digitorum muscles can result in a loss of flexion in the fingers or toes, which can significantly impact a person's ability to perform everyday tasks. Conditions such as Dupuytren's contracture and trigger finger are often associated with abnormalities in the digitorum muscles.
