Match each movement with the correct label.
Nikolay [14]

Answer:

flexion - depression

extension - elevation

adduction - medial rotation

abduction - lateral rotation

Explanation:

Flexion is the process of bending an arm or leg. It occurs as a result of the contraction of the muscles. Depression is a downward movement. Hence, flexion refers to the depression of an arm or leg.

Extension is the process of stretching the body parts. Elevation is an upward movement. Hence, extension refers to the elevation of body parts.

Adduction is the movement of a limb or other part of the body towards the midline or another part of the body. The movement of the limb towards the midline of the body is known as medial rotation.

Abduction is the movement of a limb or other part of the body away from the midline of the body. The movement of the limb away from the midline of the body is known as lateral rotation.
