Answer: (D)

Verified step by step guidance

1. Step 1: Understand the concept of directional terms in Anatomy. Directional terms are used to describe the locations of structures in relation to other structures or locations in the body.
2. Step 2: Define the term 'midline.' The midline refers to an imaginary vertical line that divides the body into equal left and right halves.
3. Step 3: Review the definitions of the given terms: - Distal: Refers to a position farther from the point of attachment or origin, typically used for limbs. - Medial: Refers to a position closer to the midline of the body. - Proximal: Refers to a position closer to the point of attachment or origin. - Lateral: Refers to a position farther away from the midline of the body.
4. Step 4: Compare the definitions to the question. The term that means 'away from the midline of the body' is 'Lateral,' as it specifically describes a position farther from the midline.
5. Step 5: Confirm your understanding by visualizing or referencing anatomical diagrams that show lateral structures, such as the arms being lateral to the chest.
