Flexor hallucis brevis muscle

The flexor hallucis brevis (Latin for " short Großzehenbeuger ") is a skeletal muscle in the bottom of the foot skeleton. It is divided into a lateral (outer) and a medial (inner) muscle belly.

Origin

The origin lies essentially in the region of the Middle sphenoid bone ( cuneiform intermedium ). Addition, however, the muscle arises also from the following structures:

  • Exterior sphenoid ( cuneiform lateral)
  • Long sole ligament ( plantar longum )
  • Calcaneocuboideum plantar ligament
  • Tendon of the posterior tibial muscle ( tibialis posterior)

Approach

The flexor hallucis brevis is divided into a lateral and a medial muscle belly:

  • The lateral part is calculated on the lateral sesamoid bone of the capsule of the first metatarsophalangeal joint and the base of the proximal phalanx of the great toe.
  • The medial part is calculated on the medial sesamoid bone of the capsule of the first metatarsophalangeal joint and the base of the proximal phalanx of the great toe.

Function

The flexor hallucis brevis flexes the big toe at the metatarsophalangeal joint ( near the body joint).
