Organ Systems
The human body is a unified organism divided into the head, neck, trunk, and limbs. It features distinct dorsal cavities (cranial and spinal) and ventral cavities (thoracic, abdominal, and pelvic), separated by the diaphragm. Connected by scapular and pelvic girdles, the limbs possess specialized free segments. Collectively, organs form systems that sustain vital functions, including sensory relation, nutrition, and reproduction.

Human body orientation relies on three fundamental axes and planes. The longitudinal, sagittal, and transverse axes define length, thickness, and width. The frontal plane divides the body into anterior and posterior sections, the sagittal plane provides bilateral symmetry (left-right), and the transverse plane separates superior from inferior parts. These geometric references are essential for precise anatomical localization.
