MUSCULUS FLEXOR DIGITORUM BREVIS Meaning and
Definition
-
Musculus flexor digitorum brevis, also known as the flexor digitorum brevis muscle, is a skeletal muscle located in the foot. Its name is derived from Latin, where "musculus" means muscle, "flexor" denotes its function of flexing or bending, "digitorum" refers to the digits or toes, and "brevis" means short. Hence, the muscle's name can be translated as the short muscle that flexes the digits of the foot.
This muscle is situated in the sole of the foot, underneath the plantar aponeurosis. It originates from the medial tubercle of the calcaneus bone, or the heel bone, and divides into four tendons that insert into the middle phalanges of the second to fifth toes. Flexor digitorum brevis functions primarily to flex the second to fifth digits of the foot, allowing for movements such as curling of the toes or gripping the ground during walking or running.
In terms of its innervation, musculus flexor digitorum brevis receives motor innervation from the medial plantar nerve, a branch of the tibial nerve that arises from the sciatic nerve in the lower leg. This nerve supplies the necessary impulses for the muscle contraction, enabling it to perform its flexion function. The flexor digitorum brevis muscle plays a crucial role in providing stability and support to the arches of the foot, contributing to balance and efficient locomotion.
