There are several different ways that the healthy human body can be studied, each from a specific point of view, providing unique information by logically organizing the body. There are seven organizational approaches to do this including; body planes and body directions, body cavities, quadrants and regions, anatomy and physiology, microscopic to macroscopic, body systems, and medical specialties. The anatomical position makes it possible to study the human body by dividing it into planes, which divides the body into two parts. The coronal plane, the sagittal plane, and the transverse plane are the three main body planes that divide the body into front and back, right and left, and top and bottom sections. The vertical plane that divides the body into front and back sections is the coronal plane, named for the coronal structure in the cranium. The anterior or ventral section of the body refers to the front, while the posterior or dorsal section refers to the back of the body. When moving from outside the body through the anterior section and then through the posterior section is the anterposterior direction. Whereas moving from outside the body through the posterior section and then through the anterior section is the posteroanterior direction. Radiology commonly uses these two directions to indicate the path of the x-ray beam. The vertical plane that divides the body into right and left sections is the sagittal plane, named for the sagittal suture in the cranium. Moving from either side of the body towards the midline is a medial direction, while moving from the midline towards either side of the body is a lateral direction. An MRI scan image of the head can be taken using the sagittal plane. The horizontal plane dividing the top and bottom sections of the body is the transverse plane; the upper half being the superior section and the lower half being the inferior...
