Anatomical terms of muscle

The flexor digitorum brevis or flexor digitorum communis brevis[1] is a muscle which lies in the middle of the sole of the foot, immediately above the central part of the plantar aponeurosis, with which it is firmly united.

Its deep surface is separated from the lateral plantar vessels and nerves by a thin layer of fascia.
