What does the sagittal plane divide the body into?

The sagittal plane divides the body into right and left halves. This anatomical plane runs vertically from front to back and is aligned parallel to the midline of the body, which bisects it into two symmetrical sections. Each half is a mirror image of the other. Understanding the sagittal plane's function is essential in fields like anatomy, physical therapy, and fitness as it helps in visualizing and assessing movements such as flexion and extension. This concept is foundational in both functional movements and in describing body mechanics during exercises and rehabilitation.

The other planes mentioned refer to different divisions: the frontal or coronal plane separates the body into front and back halves, while the transverse plane divides it into upper and lower halves. The term "inner and outer sections" does not correspond to any recognized anatomical plane.
