Muscles in the leg

What is Muscles in the leg, how painful is Muscles in the leg, classification of muscle in the leg?

This blog post will explain all you need to know about Muscle in the leg.

Leg Analyses

Basically, the leg is a region of the lower limb below the knee. The leg consists of the anterior, posterior, and lateral compartment.

There is no medial compartment of the leg (unlike the thigh).

The leg is innervated by branches of the sciatic nerve and receives its blood supply from branches of the political artery.

Drainage also occurs from the political vein and superficial drainage from the small and great sousaphones veins.

 

The anterior leg compartment consists of the following

  • Extensor digitorum longus
  • Tibialis anterior
  • Fibularis Tertius
  • Extensor hallucis longus

 

The extensor digitorum longus muscle

The extensor digitorum longus muscle is originated from the proximal half of the medial surface of the fibula and interosseous membrane, and the anterior surface of the lateral tibial condyle.

It inserts onto the dorsal surface of the middle and distal phalanges of the lateral four toes.

Its action is to extend the 2nd to 5th toes and dorsiflexion of the foot. It also assists with the inversion of the foot at the subtalar joint.

 

The tibialis anterior muscle

The tibialis anterior muscle is originated from the lateral surface of the tibial condyle and proximal shaft and inserts into the medial cuneiform bone and the base of the first metatarsal of the foot.

Its major action is the inversion of the foot at the subtalar joint, dorsiflexion of the foot at the talocrural joint, as well as the dynamic support of the medial arch of the foot.

 

The fibularis tertius muscle

The fibularis tertius muscle arises from the distal aspect of the medial fibular surface and inserts onto the base of the fifth metatarsal. Its action is to dorsiflex the ankle and to evert the foot.

 

The extensor hallucis longus muscle

The extensor hallucis longus muscle arises from the middle portion of the medial surface of the fibula and adjacent portion of the interosseus membrane and inserts onto the base of the distal phalanx of the hallux. Its action is to extend the hallux and to dorsiflex the foot.

Muscle in the leg

All muscles allocated at the leg region are all important for the movements of the ankle, and for the adjustments to the changing of surface we are walking on.

There are three major categories that are. An anterior group, a posterior group, and a lateral group.

The function ultimate of these compartments really helps us in activities such as walking, running kicking, and dancing.

This function is important to consider muscle groups as functional units. The individual muscles in each compartment may have additional functions, but the primary function of each compartment is the most important thing to remember.

 

How does blood flow through the legs?

Human blood must flow upward throughout your body to make it back to the heart – working against gravity.

The human calf and leg muscles usually assist in the pushing of blood upward, while valves (the small flaps located inside the vein), open up and allow blood to flow through. Valves close as blood passes through to keep it from flowing back down.
