ANATOMY

Detailed explanation-1: -Distal refers to sites located away from a specific area, most often the center of the body. In medicine, it refers to parts of the body further away from the center. For example, the hand is distal to the shoulder. The thumb is distal to the wrist. Distal is the opposite of proximal.

Detailed explanation-2: -Answer and Explanation: A body part that is distal is located away from a point of attachment, meaning the answer is b). The opposite of distal is proximal, which refers to a body part that is closer to a point of attachment.

Detailed explanation-3: -Distal describes a position in a limb that is farther from the point of attachment or the trunk of the body. The crus is distal to the femur. Superficial describes a position closer to the surface of the body.

Detailed explanation-4: -Proximal-toward or nearest the trunk or the point of origin of a part (example, the proximal end of the femur joins with the pelvic bone). Distal-away from or farthest from the trunk or the point or origin of a part (example, the hand is located at the distal end of the forearm).

Detailed explanation-5: -Examples of Proximal and Distal The shoulder is proximal to the elbow, as the shoulder is closer to the trunk than the elbow. Remember proximal means toward or closer to the trunk. We can also say the elbow is distal to the shoulder, as the elbow is farther away from the trunk than the shoulder.
