Which term refers to the position toward or at the midline of the body?

The term that refers to the position toward or at the midline of the body is "medial." In anatomical terminology, the midline is an imaginary vertical line that divides the body into equal right and left halves. When a structure is described as medial, it indicates that it is closer to this midline than another structure. For instance, the nose is medial to the eyes, meaning the nose is positioned nearer to the midline compared to the position of the eyes.

Understanding this concept is crucial in anatomy, as it helps clarify the locations of various body parts in relation to one another, which is essential when studying human anatomy and physiology.
