Turn sole of foot so it faces laterally

• Inversion

• Eversion

• Dorsiflexion

• Plantar flexion

Answer explanation

Eversion is the movement that turns the sole of the foot laterally, away from the midline. In contrast, inversion turns the sole medially. Dorsiflexion and plantar flexion refer to movements of the ankle, not the foot's sole.

Turn sole of foot so it faces medially

• Plantar flexion

• Dorsiflexion

• Inversion

• Eversion

Answer explanation

Inversion is the movement that turns the sole of the foot medially, bringing the inner edge closer to the midline. This distinguishes it from eversion, which turns the sole laterally.

Moving a limb away from midline

• Pronation

• Abduction

• Adduction

• Flexion

Answer explanation

Abduction refers to the movement of a limb away from the midline of the body. In contrast, adduction is the movement towards the midline, while flexion and pronation describe different types of movements.

Movement of a limb toward the body midline

• Abduction

• Flexion

• Adduction

• Pronation

Answer explanation

Adduction refers to the movement of a limb toward the body midline, while abduction is the opposite. Flexion involves bending a joint, and pronation refers to the rotation of the forearm. Therefore, the correct answer is Adduction.

Palm of hand turns from anterior to posterior.

• Pronation

• Supination

• Plantar flexion

• Flexion

Answer explanation

Pronation refers to the rotation of the forearm or hand so that the palm turns from an anterior (facing up) position to a posterior (facing down) position. Therefore, the correct answer is Pronation.

Moving palm of hand from posterior position to anterior position

• Circumduction

• Rotation

• Supination

• Pronation

Answer explanation

Supination refers to the movement of the palm from a posterior (back) position to an anterior (front) position. This action is commonly associated with turning the palm upward, distinguishing it from pronation, which is the opposite.

extension that is greater than 180 degrees and is beyond anatomical position

• flexion

• extension

• hyperextension

• abduction

Answer explanation

Hyperextension refers to an extension that exceeds 180 degrees, moving the joint beyond the anatomical position. This distinguishes it from regular extension, making hyperextension the correct choice for the given question.

lifting the foot closer to your shin (up)

• dorsiflexion

• plantarflexion

• eversion

• inversion

Answer explanation

Dorsiflexion refers to the movement of lifting the foot closer to the shin. This action decreases the angle between the foot and the leg, making 'dorsiflexion' the correct choice, while the other options describe different movements.

pointing foot toward the ground

• dorsiflexion

• plantarflexion

• inversion

• eversion

Answer explanation

Pointing the foot toward the ground is called plantarflexion. This movement involves extending the ankle joint, allowing the toes to point downward, as opposed to dorsiflexion, which points the toes upward.

The movement shown is a person moving his leg outward. This movement is known as:

• abduction

• adduction

• rotation

• flexion

Answer explanation

The movement of a leg moving outward is called abduction. This term refers to the action of moving a limb away from the midline of the body, distinguishing it from adduction, which is moving it toward the midline.
