The interosseous muscles of the foot are muscles found near the metatarsal bones that help to control the toes. They are considered voluntary muscles. They are generally divided into two sets: 4 Dorsal interossei - Abduct the digits away from the 2nd digit (away from axial line) and are bipennate.
This arrangement of dorsal interossei makes the second toe the midline of the foot, whereas the midline of the hand (marked by dorsal interossei of hand) is in the third finger. [2] Abduction is of little importance in the foot, but, together with the plantar interossei, the dorsal interossei also produce flexion at the metatarsophalangeal joints.
The bases of the other four metatarsals are connected by the dorsal, plantar, and interosseous ligaments. The dorsal ligaments pass transversely between the dorsal surfaces of the bases of the adjacent metatarsal bones. The plantar ligaments have a similar arrangement to the dorsal.
Since the intersseous muscles cross on the metatarsophalangeal joint, then they act on that specific joint and cause adduction of toes III, IV, and V. [1] Adduction itself is not of extreme importance to the toes, but these muscles work together with the dorsal interosseous muscles in flexion of the foot.
The bifurcated ligament (internal calcaneocuboid, interosseous ligament or bifurcate ligament) is a strong band, attached behind to the deep hollow on the upper surface of the calcaneus and dividing in front in a Y-shaped manner into a calcaneocuboid and a calcaneonavicular part.

The internal intercostal muscles (intercostales interni) are a group of skeletal muscles located between the ribs.They are eleven in number on either side. They commence anteriorly at the sternum, in the intercostal spaces between the cartilages of the true ribs, and at the anterior extremities of the cartilages of the false ribs, and extend backward as far as the angles of the ribs, hence ...
The interosseous intercuneiform ligaments are short fibrous bands that connect the adjacent surfaces of the medial and intermediate, and the intermediate and lateral cuneiform bones. It is one of the 3 ligaments responsible for maintaining the transverse arch of the foot together with the interosseous ligaments of metatarsals and the transverse ...
