Muscles in the foot

The extensor digitorum brevis and extensor halluces brevis on the dorsal aspect of the foot or Dosrum of the foot. The tendon passes behind the inner ankle bone medial malleolus and underneath the foot attaching to the tarsal bones.

The muscles in the anterior compartment act to dorsiflex and invert the foot as well as extend the toes.

Muscles in the foot. Some important muscles that affect the foot include. This muscle extends from the back of the knee to the heel. It is pivotal in walking and standing.

One of the large muscles of the leg it connects to the heel. It flexes and extends the. Muscles of the Foot.

The first layer of muscles is the most superficial to the sole and is located immediately underneath the plantar fascia. There are three. Medial Plantar Nerve Entrapment.

The extrinsic muscles connect to the dorsum of the foot are only two intrinsic muscles the extensor hallucis brevis and the extensor digitorum brevis. The extensor hallucis brevis of the foot that assists to extend the big toe. The third layer has the following three muscles.

Originates on the cuboid and lateral cuneiform and inserts on the proximal phalanx of the big. Originates on the bases of the second third and fourth metatarsals and inserts on the proximal. The muscles in our feet are susceptible to injuries disorders and various problems such as strains.

Many times an injured muscle in the foot will bruise and cause pain when walking. Various conditions can also make it difficult to move around. Like the muscles in the rest of the body its important to keep the muscles in the feet strong.

The extensor digitorum brevis and extensor halluces brevis on the dorsal aspect of the foot or Dosrum of the foot. All the other muscles viz -the dorsal and plantar interossei flexor digiti minimi brevis flexor halluces brevis flexor digitorum brevis quadratus plantae flexor accessorius abductor digiti minimi abductor hallucis and lumbricals are on the plantar side of the foot in the sole where they are arranged in 4 layers. The muscles tendons and ligaments The muscles are located mainly in the sole of the foot and divided into a central medial group and a group on either side lateral.

The muscles at the top of the foot fan out to supply the individual toes. The tendons are thick bands that connect muscles to bones. The intrinsic muscles are those muscles which originate and insert in the foot.

These muscles act to produce the fine movements of the toes and they also support the arches of the foot. In total there are 13 separate muscles across these three compartments. The muscles in the anterior compartment act to dorsiflex and invert the foot as well as extend the toes.

Muscles in the posterior compartment plantarflex the foot flex the toes and invert the foot. Lateral compartment muscles of the leg act to evert the foot. These can be divided up into four major groups.

The central muscles of the sole of the foot The lateral muscles of the sole of the foot The medial muscles of the sole of the foot The muscles of the dorsum top of the foot. Adductor hallucis is anatomically located in the central compartment of foot but the muscle is functionally grouped with the medial plantar muscles of foot because it acts on the great toe hallux. The adductor hallucis has two heads.

Tibialis posterior is the deepest muscle on the back of the leg. The tendon passes behind the inner ankle bone medial malleolus and underneath the foot attaching to the tarsal bones. The tibialis posterior tendon is the main invertor of the foot and also helps the calf muscles to plantarflex the foot.

Dorsum of the foot Whilst many of the extrinsic muscles attach to the dorsum of the foot there are only two intrinsic muscles located in this compartment the extensor digitorum brevis and the extensor hallucis brevis. They are mainly responsible for assisting some of the extrinsic muscles in their actions. The muscles that control the movements of the foot originate in the lower leg and are attached the bones in the foot with tendons.

These are the main muscles that facilitate movement in the foot. Tibialis posterior supports the foots arch Tibialis anterior allows the foot to move upward. This is the sec.

Adductor hallucis is a special case because it is anatomically located in the central compartment of foot but the muscle is functionally grouped with the medial plantar muscles of foot because it acts on the great toe hallux. Lower Leg Ankle Muscles The ankle muscles move the foot and include the gastrocnemius soleus tibialis posterior tibialis anterior peroneus longus peroneus brevis flexor hallucis longus flexor digitorum longus extensor hallucis longus and extensor digitorum longus. The muscles of the anterior extensor compartment of the leg are responsible for dorsiflexion of the foot.

These muscles include the tibialis anterior the extensor digitorum longus the extensor hallucis longus and the peroneus tertius. Heres the action of tibialis posterior. It inverts the foot The other muscle that can act as a foot invertor is tibialis anterior which inserts so close to tibialis posterior that it has almost the same line of action.

We looked at tibialis anterior in its role as an ankle dorsiflexor earlier in this section.
