Flexor Pollicis Longus

Examples of Flexor Pollicis Longus in the following topics:

• Muscles of the Wrist and Hand

  • Flexor Digitorum Profundus - A long muscle originating near the elbow and passing through into the wrist, lying adjacent to the flexor pollicis longus.
  • Flexor Pollicis Longus - A long muscle originating near the elbow and passing through into the wrist, lying adjacent to the flexor digitorum profundus.
  • Abductor Pollicis Longus – The abductor pollicis longus is situated immediately distal to the supinator muscle.
  • Extensor Pollicis Brevis – The extensor pollicis brevis is located below the abductor pollicis longus.
  • Abductor Pollicis Brevis – Located anteriorly to the opponens pollicis and proximal to the flexor pollicis brevis.

• Muscles that Cause Movement at the Foot

  • Quadratus Plantae - The quadratus plantae muscle is located superior to the flexor digitorum longus tendons.
  • Attachments - Originates from the heel and attaches to the tendons of flexor digitorum longus.
  • Actions - Assists flexor digitorum longus in flexing the lateral four toes.
  • Lumbricals - The lumbricals are four small skeletal muscles, accessory to the tendons of the flexor digitorum longus and numbered from the medial side of the foot.
  • Attachments - Originates from the tendons of flexor digitorum longus.

• Tibia and Fibula (The Leg)

  • These muscles originate from the fibula's surface and include the extensor digitorum longus, soleus, and flexor hallucis longus, among others.

• Shin Splint Syndrome

  • Muscle imbalance, including weakened core muscles lead to more lower-extremity injuries; also the inflexibility and tightness of the gastrocnemius, soleus, and plantar muscles (commonly the flexor digitorum longus) can contribute to shin splints.
