Origin: Originated from base and medial side of metatarsals 3-5

Insertion: It inserted into bases of proximal phalanges and extensor expansions of digits 3-5

Innervation: The muscle innervated by deep branch of the lateral plantar nerve

Action: Adduct digits 3-5 (move these digits toward the midline of the foot as defined by a plane through the second digit); flex the metacarpophalangeal and extend interphalangeal joints of digits 3-5

Origin: As part of tibialis posterior muscle, the tendon originated from the posterior surface of the tibia and fibula, and the interosseous membrane in the upper two-thirds of the lower leg.

Insertion: It inserted into

Navicular bone: The main insertion is on the tuberosity of the navicular bone, the largest bone on the medial side of the foot.

Cuneiforms: Tendon slips extend to the medial, intermediate, and lateral cuneiform bones

Cuboid: A tendon slip also attaches to the cuboid bone on the lateral side of the foot

Metatarsals: Tendon slips insert on the bases of the second, third, and fourth metatarsals (bones of the forefoot)

Sustentaculum tali: A small tendon slip attaches to the sustentaculum tali, a bony part of the calcaneus (heel bone)

Action:

Inversion: It helps to turn the sole of the foot inward

Plantarflexion: It assists in the downward movement of the foot (pointing the toes)

Foot arch support: It plays a crucial role in maintaining the shape and function of the foot arch

Ankle joint stabilization: It helps to stabilize the medial side of the ankle joint

Origin: As part of fibularis longus muscle, the tendons originated from the head and proximal two-thirds of the lateral surface of the fibula, as well as the adjacent intermuscular septum

Insertion: It inserted onto the medial cuneiform and base of the first metatarsal bone

Action:

Eversion: Plays a crucial role in eversion of the foot, allowing the sole of the foot to turn outward

Plantarflexion: Assists in plantar flexion

Arch Support: Support of the lateral and transverse arches of the foot

Source: Originated from lateral plantar artery

Branches: It gives branches to

Perforating Branches: The plantar arch gives off perforating branches that connect with the dorsal metatarsal arteries

Plantar Metatarsal Arteries: It also gives rise to plantar metatarsal arteries (three to four), which supply the toes

Supply to: It supplies to the plantar tissues and muscles of the foot

Source: Originated from plantar arch artery

Branches: It gives branches to common plantar digital arteries

Supply to: It supplies to the interosseous muscle, deep portions of the foot; digits including the dorsum of the distal phalangeal segment
