Situated behind or toward the rear; back part of the body.

• A. Pronation
• B. Posterior
• C. Medial
• D. Lateral Recumbent

Answer: (B)

In anatomical terms, the word posterior describes the back portion of the body or something situated toward the rear. It’s the opposite of anterior, which means the front. So when you say the back part of the body or the behind-side location, you’re using posterior.

Pronation isn’t about location on the body; it’s the rotation of the forearm (palm turning downward) or the foot turning inward. Medial refers to a position toward the midline of the body, not the back. Lateral recumbent is a patient position—lying on one side—not a descriptor of where a body part is located.
