MEDICAL PHYSIOLOGY

Detailed explanation-1: -The tibialis anterior is a long, thin muscle located at the front of the lower leg in the shin, and it is the agonist of dorsiflexion.

Detailed explanation-2: -The tibialis anterior (TA) is the strongest dorsiflexor of the foot. Dorsiflexion is critical to gait because this movement clears the foot off the ground during the swing phase.[3] The tibialis anterior, along with the tibialis posterior, is also a primary inverter of the foot.

Detailed explanation-3: -The main action of tibialis anterior is to produce dorsiflexion at the ankle.

Detailed explanation-4: -The muscle that is antagonistic to the tibialis anterior is the peroneus longus. The main function of the tibialis anterior is dorsiflexion of the foot and inversion of the foot. An overuse injury which causes microtrauma to this muscle leads to a condition known as shin splints.
