Leg Muscles and Ligaments

The leg, anatomically defined as the region of the lower limb below the knee, is a complex structure that includes various muscles and ligaments. These components work together to enable movements such as walking, running, jumping, and flexing the feet.

Muscles of the Leg

The leg muscles are organized into three groups:

1. Anterior (dorsiflexor) group: This includes the tibialis anterior, extensor digitorum longus, fibularis tertius, and extensor hallucis longus. These muscles help lift and lower your foot, extend your toes, and are crucial for the swing phase of the gait cycle.

2. Posterior (plantar flexor) group: Comprising of the gastrocnemius, plantaris, soleus, tibialis posterior, flexor hallucis longus, popliteus, and flexor digitorum longus. These muscles help flex and point your toes, jump, run, push off into a sprint, lock and unlock your knee, maintain good posture by stabilizing your legs, and stand up straight by supporting the arch of your foot.

3. Lateral (fibular) group: Consists of the fibularis longus and fibularis brevis. These muscles stabilize your foot when walking or running and allow you to move your foot from side to side.

Ligaments of the Leg

Ligaments are connective tissues that help support and stabilize joints. They are crucial for the proper functioning of the leg, providing stability and facilitating movement.


The leg’s muscles and ligaments play a vital role in our daily activities, from simple tasks like standing and walking to more complex actions like running and jumping. They work in harmony to provide stability, support body weight, and enable movement. Understanding their structure and function is essential for maintaining leg health and managing potential injuries..
