What is the term for the vertical plane that divides the body into right and left sides?

The term that refers to the vertical plane dividing the body into right and left sides is known as the sagittal plane. This plane runs parallel to the midline of the body, allowing for the division of the body into two symmetrical halves—right and left. When discussing anatomical planes, understanding the sagittal plane helps clarify many concepts in human anatomy and movement, particularly in how body parts relate to one another and move in relation to central structures.

The median plane, which is sometimes referred to in discussions about the sagittal plane, specifically denotes the exact center division of the body into equal right and left halves. While it relates closely to the more general definition of the sagittal plane, it is distinct in that it specifies the median line.

Additionally, the coronal plane divides the body into anterior (front) and posterior (back) sections, while the lateral plane is less commonly used in this context, as lateral typically refers to the sides of the body rather than a specific dividing plane. Understanding these different anatomical terms reinforces spatial orientation in the study of biology and human anatomy.
