Which term refers to the median plane of the body?

The term that refers to the median plane of the body is "midline." The midline is an imaginary line that divides the body into equal right and left halves. It serves as a central reference point for assessing body symmetry and positioning. Anatomical terms often use this midline as a basis for describing locations, directions, and movements of body structures or limbs. For example, structures closer to the midline are termed "medial," while those farther away are described as "lateral." This understanding of the midline is crucial for navigating the complexities of human anatomy, especially in clinical and fitness contexts.
