The anterior muscles of the leg are a group of muscles located in the front (anterior) part of the leg. These muscles are responsible for various movements and functions of the leg, including flexion, extension, and dorsiflexion of the foot.
The main anterior muscles of the leg include:
1. Tibialis anterior: This muscle is located on the front of the shin and is responsible for dorsiflexion of the foot, which means lifting the foot upwards towards the shin. It also helps in inversion of the foot, which is turning the sole of the foot inward.
2. Extensor digitorum longus: This muscle runs along the front of the leg and is responsible for extending the toes. It helps in lifting the toes off the ground and assists in dorsiflexion of the foot.
3. Extensor hallucis longus: This muscle is located next to the tibialis anterior and is responsible for extending the big toe. It assists in dorsiflexion of the foot and helps in propelling the body forward during walking or running.
4. Peroneus tertius: This muscle is located on the outer side of the leg and assists in dorsiflexion and eversion of the foot. It also helps in stabilizing the ankle joint.
These anterior muscles of the leg work together to provide stability and control during various movements of the leg and foot. They are essential for activities such as walking, running, and maintaining balance.
