plantaris

[planter′is, plantä′ris]
Etymology: L, planta
one of three superficial muscles at the back of the leg, between the soleus and the gastrocnemius. The plantaris is a small muscle that arises from the distal part of the linea aspera of the femur and from the oblique popliteal ligament of the knee joint. It has a small fusiform belly, ending in a long, slender tendon that inserts into the calcaneus. The plantaris is innervated by a branch of the tibial nerve containing fibers from the fourth and the fifth lumbar and the first sacral nerves. It plantar-flexes the foot and the leg. Compare gastrocnemius, soleus.

plantaris

small muscle within superficial compartment of posterior aspect of lower leg (see Table 1 and Table 2)
  • origin popliteal surface of femur, deep to lateral head of gastrocnemius

  • insertion via a long, slender tendon, into Achilles tendon

  • nerve supply tibial nerve

  • action facilitates toe off; its tendon may serve as donor tissue in surgical repair of ruptured Achilles tendon

The nerve supply to the lower limb (lower leg and foot) is derived from the sciatic and femoral nerves. Dysfunction or compromise of either of these nerves causes marked motor, sensory and autonomic effects in the lower leg and foot.

MTPJ, metatarsophalangeal joint; IPJ, interphalangeal joint.

1. plantar.
2. the superficial digital flexor muscle of the hindlimb.
