What is a midline?

A midline is an imaginary line that divides the body into left and right halves. It runs vertically from the top of the head to the feet, bisecting the body in half. The midline is important in anatomy and physiology as it helps to locate and describe the position of organs, structures, and anatomical landmarks in the body. It is also used as a reference point in medical examinations, surgeries, and diagnostic imaging. Understanding the midline is essential for healthcare professionals to accurately assess and treat patients.
