Flexor digiti minimi brevis muscle (foot)
Encyclopedia
The Flexor digiti minimi brevis (Flexor brevis minimi digiti, Flexor digiti quinti brevis) lies under the metatarsal bone of the little toe, and resembles one of the Interossei
.
It arises from the base of the fifth metatarsal bone
, and from the sheath of the Peronæus longus; its tendon is inserted into the lateral side of the base of the first phalanx
of the fifth toe.
Occasionally a few of the deeper fibers are inserted into the lateral part of the distal half of the fifth metatarsal bone; these are described by some as a distinct muscle, the Opponens digiti quinti.
Interossei

Fifth metatarsal bone
The fifth metatarsal bone is recognized by a rough eminence, the tuberosity, on the lateral side of its base.The base articulates behind, by a triangular surface cut obliquely in a transverse direction, with the cuboid; and medially, with the fourth metatarsal.On the medial part of its dorsal...

Phalanx bones
In anatomy, phalanx bones are those that form the fingers and toes. In primates such as humans and monkeys, the thumb and big toe have two phalanges, while the other fingers and toes consist of three. Phalanges are classified as long bones.The phalanges do not have individual names...
