• A. Toward the midline of the body
• B. Closer to the point of attachment or origin of the limb (nearer the trunk)

• D. Farther from the point of attachment or origin of the limb (farther from the trunk)

Answer: (B)

Verified step by step guidance

1. Understand that anatomical directional terms describe locations or positions of structures relative to other parts of the body.
2. Recognize that the term 'proximal' is specifically used to describe positions on the limbs (arms and legs).
3. Recall that 'proximal' means closer to the point where the limb attaches to the trunk of the body, which is the origin or base of the limb.
4. Contrast 'proximal' with 'distal,' which means farther from the point of attachment or origin of the limb.
5. Therefore, 'proximal' refers to a position on a limb that is nearer to the trunk, not toward the midline or the back side of the body.
