Verified step by step guidance1
Understand the concept of joint movements: In anatomy, joint movements are described in terms of the angle between bones. These movements include flexion, extension, abduction, adduction, and hyperextension.
Define flexion: Flexion is the action of decreasing the angle between two bones at a joint. It typically involves bending a limb or joint, such as bending the elbow or knee.
Differentiate between the options: Adduction refers to moving a limb toward the body's midline, hyperextension is extending a joint beyond its normal range, extension is increasing the angle between bones, and abduction is moving a limb away from the body's midline.
Identify the correct term: Since flexion involves decreasing the angle between bones, it is the correct term for the action described in the problem.
Apply the knowledge: Use this understanding to correctly identify flexion as the action of decreasing the angle between bones in various anatomical contexts, such as when performing exercises or understanding joint mechanics.
