It flexes your knees and allows flexing and movement of your hips. If you pick your foot up and look at the sole of your foot then you are using all the functions of the sartorius muscle.
Tibialis Anterior
The gastrocnemius muscle belongs to the muscular system. It is a major muscle located in the calf region of the leg and is responsible for plantar flexion of the foot at the ankle joint.
fibularis tertius
The opposite muscle to the tibialis anterior is the gastrocnemius muscle, which is located at the back of the lower leg. The tibialis anterior is responsible for dorsiflexion of the foot (bringing the toes toward the shin), while the gastrocnemius is responsible for plantarflexion of the foot (pointing the toes away from the shin).
The largest muscle of your calf is the gastrocnemius.
There are two: the extensor digitorum (toes) brevis muscle and the extensor hallucis (big toe) brevis muscle.
Flexing or moving the sole of your foot.
The muscle responsible for moving the foot upwards is the tibialis anterior. This muscle is located in the front of the leg and helps with dorsiflexion of the foot, which raises the toes towards the shin.
The extensor digitorum longus muscle is responsible for extending the toes (digits) and dorsiflexing the foot at the tarsal joint.
Eversion is when the foot is curved away from the other foot and is controlled by peroneus longus and peroneus brevis. Inversion is when the foot curves the opposite way, towards the other foot, and is controlled by tibialis anterior and tibialis posterior. The subtalar joint or talocalcaneal joint is the joint that is responsible for creating inversion and eversion in the foot. This joint plays no part in the flexing of the foot though.
The tibialis anterior muscle inserts onto the base of the first metatarsal and the medial cuneiform bone. It is responsible for dorsiflexion of the foot and inversion of the ankle.
