The leg muscle constitutes a significant mass or weight of an individual. It is packed with bones, cartilages, tendons, muscles, blood, nerves, and other structure. The leg muscle anatomy does not work alone. It needs to work together with other body structure to accomplish efficient performance. The lower leg could be viewed from the front view and the back view. Normally the shin is used to pertain to the front of the leg while the calf is at the back.

Different Divisions of the Leg Muscle Anatomy

The lower leg could be divided in different manners. This is done to facilitate fast and convenient way to manage and identify different parts of the leg muscles. But the most common way to divide the leg muscle anatomy is according to their compartment.

Four Lower Leg Compartments

  • Deep posterior compartment – located at the deep inside of the back leg. It contains the flexor hallucus longus, flexor digitorum longus, and the tibialis posterior. The flexor hallucus longus aids in flexing the big toe. The digitorum longus helps in flexing the four toes except the big toe. Finally, the tibialis posterior flexes the foot towards the body.Gastrocnemius - Leg muscle anatomyCredit: - Muscle anatomy of the legCredit: muscle - Anatomy of the leg muscleCredit:
  • Posterior compartment – this contains the large muscle groups which include the gastrocnemius, plantaris and soleus muscle. The gastocnemius, also known as calf muscle, has two attachments to the bones, the inner and outer. It is a short and thick muscle that is very visible. The soleus is located just underneath the calf muscle. Together with the plantaris, these muscles are attached to the bones through the Achilles tendon. The posterior compartment helps in performing plantarflexion.Lateral compartment - Leg muscle anatomyCredit:
  • Lateral compartment – the lateral lower leg muscles run along the outside of the posterior leg. It consists of the peroneus longus and peroneus brevis muscles. Its main functions have to do foot eversion and pointing the foot (plantarflexion).Peroneus tertius - Anatomy of the leg muscleCredit: hallucus longus - Anatomy leg muscleCredit: digitorum longus - Muscle of the leg anatomyCredit: anterior - Leg muscle anatomyCredit:
  • Anterior compartment – this pertains to the shin of the leg. It consists of several muscles such as the peroneus tertius, extensor hallucus longus, extensor digitorum longus, and tibilais anterior. Generally, all these muscles help in dorsiflexing the foot and toes. The tibialis anterior helps in foot inversion.


Summary of the Leg Muscles

It is very common for many people to use their lower leg muscle in their everyday life. The lower leg muscles play a vital role in performing our activities of daily living. The leg muscle anatomy has many parts just like other muscles of the body.

The need for additional knowledge about the lower leg is very important. This article should have given you a brief background of the leg muscle anatomy.
