D)

Explanation / Answer
19) Inversion is movement of the sole towards the median plane. Turning the sole medially
20) Eversion is turning the sole of the foot away from the midline of the body. Eversion is turning the sole laterally.
21) Plantar flexion is the movement where the angle between the sole of the foot and the back of the leg is reduced. This is by Downward movement of the foot.
22) In dorsiflexion, the toes are brought close to the skin. This is by reducing the angle between the foot and the leg.
40) A conical movement of the limb from the joint is called Circumduction. It is a 360 degree movement. So circumduction is a movement in a circle
