The frontal plane, also known as the coronal plane, is an anatomical boundary that divides the body into anterior (front) and posterior (back) sections. It runs vertically from side to side, allowing for movements such as lateral flexion and abduction. This plane is essential in fields like anatomy, physical therapy, and sports science for understanding body movements. In imaging techniques, such as MRI or CT scans, the frontal plane provides a clear view of the body's structures from the front or back. It helps healthcare professionals assess conditions and plan treatments by visualizing organs and tissues in relation to this plane.
