The human body's structure and function are described using specialized terminology in anatomy and physiology. This guide covers anatomical position and directional terms, body planes and sections, and body cavities, providing essential knowledge for understanding human anatomy.
Anatomical position serves as a standard reference point, while directional terms help describe the location of body parts relative to each other. The three main body planes - sagittal, frontal, and transverse - are used to visualize the body's internal structure. Body cavities house and protect vital organs, with major cavities including the cranial, thoracic, and abdominal cavities.
