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 understanding human anatomy and movement. In medical imaging, the frontal plane is often used in techniques like X-rays and MRI scans to provide clear views of the body's structures. It helps healthcare professionals assess conditions affecting the chest, abdomen, and limbs, facilitating accurate diagnoses and treatment plans.
