Question

the number 5 on the figure demonstrates ______.

multiple choice

adduction

Explanation:

Identify the joint and movement shown

The diagram illustrates various body movements. The figure on the right shows movements of the lower limb at the hip joint.

• Arrow 3 (pointing backward) represents extension of the thigh at the hip joint.
• Arrow 5 (pointing forward/upward) represents flexion of the thigh at the hip joint, moving the limb anteriorly.
• Arrow 4 represents flexion at the knee joint.

Apply anatomical terminology

Using the Anatomical Terminology and Muscle Actions knowledge points:

• Flexion is a movement that decreases the angle between two body parts (moving the limb anteriorly at the hip).
• Extension is a movement that increases the angle between two body parts (moving the limb posteriorly at the hip).
• Therefore, the arrow labeled 5 demonstrates flexion of the hip/thigh.

Answer:

• adduction
• abduction
• extension
• flexion (Correct answer)
