Anatomy of a human -General Anatomy
Three general principles are recognizable in the architecture of the human organism:
1. The principle of polarity: Polarity is reflected mainly in the formal and functional contrast between the head (predominantly spherical form) and the extremities (radially arranged skeletal elements). In the phylogenetic development of the upright position of the human body, polarity developed also among the extremities: The lower extremities provide the basis for locomotion whereas the upper extremities are not needed anymore for locomotion, so they can be used for gesture, manual and artistic activities.
2. The principle of segmentation: This principle dominates in the trunk. The anatomical structures (vertebrae, pairs of ribs, muscles, and nerves) are arranged segmentally and replicate rhythmically in a similar way.
3. The principle of bilateral symmetry: Both sides of the body are separated by a midsagittal plane and resemble each other like image and mirror-image.

important abdominal organs (intestinal
tract, liver, pancreas) are arranged
unpaired. Their functions remain
