Description

Origin: Metatarsals

Insertion: Proximal phalanges

Nerve: Plantar nerve

Action: Adduct toes

Antagonist: Dorsal interossei of the foot

Description:
The Interossei in the foot are similar to those in the hand, with this exception, that they are grouped around the middle line of the second digit, instead of that of the third.They are seven in number, and consist of two groups, dorsal and plantar.

The Interossei plantares (Plantar interossei), three in number, lie beneath rather than between the metatarsal bones, and each is connected with but one metatarsal bone. They arise from the bases and medial sides of the bodies of the third, fourth, and fifth metatarsal bones, and are inserted into the medial sides of the bases of the first phalanges of the same toes, and into the aponeuroses of the tendons of the Extensor digitorum longus.
