Which term means closer to the midline of the body?

• A. Medial
• B. Proximal
• C. Superficial
• D. Plantar

Answer: (A)

Anatomical directional terms describe where a structure is in relation to others, and the term that means closer to the midline is medial. The midline is that imaginary vertical line dividing the body into left and right halves, so structures toward this line are described as medial. For example, the nose is medial to the cheeks, and the big toe is medial to the little toe.

Other terms describe different relationships: proximal means nearer to the trunk or point of attachment, superficial means closer to the body surface, and plantar refers to the sole of the foot.
