The nervous system encompasses the activity of brain, cranial nerves, pituitary, spinal cord and spinal nerves. From the brainstem emerge twelve cranial nerves: olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharyngeal, vagus, accessory and hypoglossal.
On the basis of the constant accumulation of experiences, the nervous tissue forms a person's self-awareness and personal identity. It also includes the endocrine glands, which serve as control centers in the body and are linked to the activity of the seven chakras. The endocrinal glands release hormones directly into the bloodstream. Their function secures the process of procreation, growth, development, metabolism and balance of life functions.
Healthy nervous tissue enables clear perception and correct understanding, enhances life energy and optimism, and develops charisma and intuition. A by-product of this tissue is the fluid of the white of the eyes, tears and eye secretions.
