1. 무지외전근(Abductor Hallucis)

The Abductor Hallucis lies along the medial border of the foot and covers the origins of the plantar vessels and nerves. It arises from the medial process of the tuberosity of the calcaneus, from the laciniate ligament, from the plantar aponeurosis, and from the intermuscular septumbetween it and the flexor digitorum brevis.

The fibers end in a tendon, which is inserted, together with the medial tendon of the flexor hallucis brevis, into the tibial side of the base of the first phalanx of the great toe. It is responsible for abducting the great toe.

Innervation[edit]

Abductor hallucis is innervated by the medial plantar nerve.

Variations[edit]

Slip to the base of the first phalanx of the second toe

2. 단지굴근(Flexor Digitorum Brevis)

The flexor digitorum brevis 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.

Structure[edit]

It arises by a narrow tendon, from the medial process of the tuberosity of the calcaneus, from the central part of the plantar aponeurosis, and from the intermuscular septa between it and the adjacent muscles.

It passes forward, and divides into four tendons, one for each of the four lesser toes.

Opposite the bases of the first phalanges, each tendon divides into two slips, to allow of the passage of the corresponding tendon of the flexor digitorum longus; the two portions of the tendon then unite and form a grooved channel for the reception of the accompanying long Flexor tendon.

Finally, it divides a second time, and is inserted into the sides of the second phalanx about its middle. The mode of division of the tendons of the flexor digitorum brevis, and of their insertion into the phalanges, is analogous to that of the tendons of the flexor digitorum superficialis in the hand.

Innervation[edit]

Innervation is by the medial plantar nerve.

3. 소지외전근(Abductor Digiti Minimi)

The abductor digiti minimi (abductor minimi digiti, abductor digiti quinti) is a muscle which lies along the lateral (outer) border of the foot,^[1] and is in relation by its medial margin with the lateral plantar artery, vein and nerves. It homolog in the arm is the abductor digiti minimi muscle in the hand.

Origin and insertion[edit]

It arises, by a broad origin, from the lateral process of the tuberosity of the calcaneus, from the under surface of the calcaneus between the two processes of the tuberosity, from the forepart of the medial process, from the plantar aponeurosis, and from the intermuscular septum between it and the flexor digitorum brevis.^[2]

Its tendon, after gliding over a smooth facet on the under surface of the base of the fifth metatarsal bone, is inserted, with the flexor digiti quinti brevis, into the fibular side of the base of the first phalanx of the fifth toe.^[2]

Innervation[edit]

The abductor digiti minimi is innervated by the lateral plantar nerve, a branch of the tibial nerve.

Function[edit]

Its function is flexion^[3] and abduction of the fifth (little) toe at the metatarsophalangeal joint.^[2][3]

Clinical relevance[edit]

Due to its role in posture during all physical activity while in an upright position, the abductor digiti minimi is often the target of injury. The most common of such injuries occurs mainly in women and is referred to as orteil de belette, commonly known as Weasel Toe.^{[citation needed] - 족제비 발}

In case of polydactyly it may insert to the sixth toe instead, if there is one.^{[citation needed]}
