The cerebellum is the seat of the BRAIN CENTER from which SPIRIT coordinates and regulates the muscles of the body. The activity of this center is largely of a reflex nature in origin and is excited by impulses which come to it from peripheral organs.
In this activity, as in other forms of reflex activity, the mechanism involves: (1) afferent nerves, e.g., cutaneous, muscle, optic, and vestibular, and their related end organs, tactile corpuscles, muscle spindles, retina, and semicircular canals, all indirectly connected with (2) the cerebellar centers; (3) efferent nerves indirectly connected with (4) the general musculature of the body. Both station and progression are directly dependent on the development and transmission of afferent impulses from the previously mentioned peripheral sense organs to the cerebellum. Tactile, muscle, visual, and labyrinthine impressions and sensations not only cooperate in the development and organization of the motor adjustments necessary to the maintenance of the equilibrium and locomotive coordination but, even after their organization, they are necessary to the excitation of cerebellar activity.
Any injury or shock, either physical or emotional, will distort the normal nerve functioning of the FIFTH ZONE, resulting in a disruption not only of the equilibrium of the body but also a displacement of the center of gravity of the body.
As stated previously, the BRAIN CENTER, from which INNATE controls and regulates the muscles of the body, is located in the cerebellum.
This zone is composed of the following areas:
- FIFTH CERVICAL
- FIFTH THORACIC
- ELEVENTH THORACIC
- FIFTH LUMBAR
