The anterior compartment of the thigh is involved in lower leg extension. the anterior compartment of the thigh is involved in lower leg extension. a. true b. false

The answer to this question would be: true

The muscle in the anterior of the thigh will cause the lower leg to extend. Muscle can only apply force by becoming shorten. This process will be called a contraction. If the muscle in the anterior thigh shortens, the movement should extend the lower leg.
That means the muscle in the posterior part of the thigh should cause the lower leg flexion.

The answer is True. This is the correct answer because the anterior part of the thigh is the quadriceps femoris muscle. When this muscle contracts or shortens, it pulls on tendons attached to the tibia bone or lower leg bone, thus extending it outward. The anterior thigh muscle does in fact cause a leg extension.
