Old Mesoderm

In conventional embryology, three germ layers are recognized: inner (endoderm), middle (mesoderm), and outer (ectoderm). In GNM, however, we see two distinct germ layers in the middle that respond very differently from one another and govern very different tissues and conflict responses. The old mesoderm is the inner of these two middle layers.

The old mesoderm produces the membranes and coverings that protect the body's internal organs and surfaces: the pleura (lung lining), the pericardium (heart lining), the peritoneum (abdominal lining), the meninges (brain and spinal cord lining), the dermis (inner skin layer), the amniotic sac around a mammal fetus or the shell membrane of an egg, and similar protective tissues throughout the body. Also belonging to the old mesoderm are the breast glands and sweat glands — specialized invaginated corium skin.

Old mesoderm tissues are part of the old brain group, relayed through the cerebellum. The biological conflicts associated with old mesoderm tissues are attack conflicts: experiences in which the psyche registers a threat to the physical integrity of the body or to a protected inner space; a conflict of being attacked, violated, soiled, or defiled. Worry conflicts (such as nest-worry about a loved one or worrying about something inside the body) are also relayed through the cerebellum.

During the conflict-active phase, old mesodermal tissues respond by growing (cell proliferation), forming melanomas, mesotheliomas or other thickenings. The biological purpose of these types of tumours is to create additional protection over or around the area the organism is worrying about.

When the conflict resolves, bacteria and mycobacteria (and, to a lesser extent, fungi) move in during the healing phase to break down the excess protective tissue. The discomfort, inflammation, and drainage associated with this process — often diagnosed as pleurisy, pericarditis, peritonitis, or meningitis — are healing-phase events.

Unlike endoderm tissues, old mesoderm tissues have crossover and are subject to laterality. The capacity for mother-child and partner relating begins at the cerebellum: a nest-worry (or argument) conflict will involve the breast gland on the dominant or non-dominant side, depending on the relationship involved in the conflict content. The right side of the cerebellum controls old mesoderm tissues on the left side of the body, and vice versa.
