Verified step by step guidance1
Understand the definition of flexion: Flexion is a movement that decreases the angle between two body parts. For example, bending the elbow or knee results in flexion.
Consider the definition of abduction: Abduction is the movement of a limb away from the midline of the body. It does not involve decreasing the angle of a joint.
Examine the definition of rotation: Rotation involves turning a body part around its axis, such as turning the head side to side. It does not specifically decrease the angle of a joint.
Review the definition of extension: Extension is the opposite of flexion, where the angle between body parts increases, such as straightening the elbow or knee.
Identify the correct type of movement: Since the problem specifies a decrease in the angle of a joint, the correct type of movement is flexion.
