What is the sagittal plane's primary function in the body?

The primary function of the sagittal plane is to divide the body into right and left portions. This anatomical plane runs vertically from front to back and allows for the examination and description of movements or structures in relation to the right and left sides of the body. It is fundamental in understanding movement patterns such as flexion and extension, which occur primarily in this plane.

In practical applications, movement in the sagittal plane is common in activities such as walking, running, and bending, where the body moves forward or backward. Understanding how the sagittal plane operates is essential for professionals in sports medicine, as it provides insight into biomechanics and the functional anatomy of the body.
