The sternum is _____________ to the axilla (armpit).

The correct answer is that the sternum is medial to the axilla (armpit). In anatomical terms, "medial" refers to a position that is closer to the midline of the body when compared to another structure. The sternum, or breastbone, is centrally located in the chest, while the axilla is situated more towards the sides of the body. Therefore, when considering their relative positions, the sternum is indeed closer to the midline than the axilla, making it a medial relationship.

Understanding this concept is vital, as it helps in accurately describing the locations of various parts of the body in relation to each other, which is particularly useful in first aid, emergency response, and medical settings.
