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.

skull

Horizontal section through the head at the level of the eyes.

There are also different principles in
the architecture and function of the
inner organs:
The skull contains the brain and the
sensory organs. They are arranged
like mirror and mirror-image and are
the basis of our consciousness.
thorax

Coronal section through the thoracic and abdominal cavity.

The thorax contains the organs of
the rhythmic system (heart, lung),
which are only to some extent
bilaterally organized. The consciousness
(feeling, etc.) is located inbetween.
In the abdominal cavity, the most
important abdominal organs (intestinal
tract, liver, pancreas) are arranged
unpaired. Their functions remain
subconscious.
