Overview

3rd layer of the muscles of the sole of the foot

Origin

  • Cuboid
  • Lateral cuneiforms
  • Plantar calcaneocuboid lig

Other sources state that the /The Archive/Anatomy/Skeletal Muscles/Lower limb muscles/Ankle and Foot/Intrinsic Dorsal Foot Muscles/flexor_hallucis_brevis.html#abbreviation originates from the

Insertion

Base of proximal phalanx 1st toe (via med and lateral sesamoids)

“More recently, a study of 42 cadaveric specimens also verified that the adductor hallucis inserts into the lateral sesamoid and has a conjoined tendon with the FHB which then inserts into the base of the proximal phalanx”

  • quote source

“The medial and lateral heads of the FHB insert onto distinct locations at the base of the proximal phalanx”

Innervation

Action

  • 1st MTP: Flexion
  • Longitudinal arch: Support

MMT

“The FHB VIDEO and FHL muscles VIDEO produce MTP joint flexion and IP joint flexion. The foot is maintained in midposition. The first metatarsal is stabilized, and resistance is applied beneath the proximal and distal phalanx of the great toe into toe extension.”
