Seven Organizational Approaches There are seven organizational approaches to study the human body which are body planes and body directions‚ body cavities‚ quadrants and regions‚ anatomy and physiology‚ microscopic to macroscopic‚ body systems and medical specialties. Each approach can provide a specific point of view and provides unique information by dividing or organizing the body in a logical way (Turley‚ 2011). There are three main body planes: the coronal or frontal plane‚ the sagittal
