#germ layers

The fertilized egg, travels through the oviduct and before even the implantation onto the urine tract, it has turned from one enormous cell to blastocyst - as the rapid mitotic divisions take place. When the rate of these divisions slows down, our ball of cells will become a gastrula (from a blastula) as the cells rearrange themselves and start organization into the three germ layers: ectoderm, mesoderm and endoderm. Let's start with the first one. What is this ectoderm layer? Is it the layer form which epidermis cells will arise (skin cells) and your nervous system. The neural tissue is induced after the organizer, autonomous cells which determine neurulation and other events, this is a very important structure as the experiments have shown that if we transplant the organizer from the blastopore of a frog into another embryo, an additional embryo will form. So it has the capability to induce formation of a second individual! (Which will be connected to the first). It's job is tremendous as it will induce the formation of the nervous system and from gastrula, we will move on to the stage called neurula. Here, neurulation will take place which is the folding process of the neural plate into neural tube. It is called neural plate because at first it is just part of the embryo, flat-like top (anterior) structure. But when a node of mesodermal cells (middle layer) tell the ectodermal cells above them that they are not going to become epidermis but instead form the nervous system, it all changes.

SO when this rod of mesodermal cells, or notochord, induces the formation of neural tube, first the cells above it will elongate and then begin to fold, forming a tube-like structure. This happens because of the cytoskeleton of the cells which can allow them to constrict their "necks" and thus acquire the mechanical force to pull themselves together and then elongate. Neural crest cells play a part here because they are part of the neural plate and when the folding begins, they will elevate themselves to form a "circle" (the to be neural tube) below them and thus close it.

Three primary germ layers are formed during gastrulation: ectoderm, mesoderm, and endoderm.

Ectoderm: (ectodermal cells develop into the outer coverings of the body, e.g. outer layers of skin, nails, and tooth enamel, and into the cells of the nervous system and sense organs) Epidermis of skin, nervous system, sense organs

Mesoderm: (structures lying between the inner and outer coverings of the body) Skeleton, muscles, blood vessels, heart, blood, gonads, kidneys, dermis of skin

Different parts of the brain correspond to different organs, which are developed from the different germ layers that I wrote about last week.

The Cerebral Cortex corresponds with the Ectoderm tissue.

The Cerebral Medulla corresponds with the New Brain Mesoderm.

The Cerebellum corresponds with the Old Brain Mesoderm.

The Brain Stem corresponds with the Endoderm tissue.

 Below is a picture taken from Dr. Hamer’s book. He makes it easy to follow because he color coordinates each of the germ layers with each part of the brain.

When a DHS hits, it affects us on all 3 levels at the exact same time... the psyche, the brain, and the corresponding organ. Every DHS has a theme based on our beliefs, our experiences and our perceptions of those experiences. This theme will determine where the conflict hits us on an organ level. For example, if I were to experience a “death fright” theme it would hit me in the lung(s); a “worry in the nest” theme would hit me in the breast.

Dr. Hamer calls these themes “biological conflicts” because we have no control over them. These biological conflicts determine the location of the program running in the brain and the location on the corresponding organ.

In the next couple of weeks I will be writing about germ layers so I feel the need to explain exactly what a germ layer is, as simply as I can, and although it can certainly go much deeper than my explanation, how Dr. Hamer uses these tissues in explaining his work. 

Basically, when an egg is fertilized it then divides (remember your biology class?) and forms three cellular layers called ectoderm (outer layer), mesoderm (middle layer) and endoderm (inner layer). These layers will give rise to all of the body’s tissues and organs.

For example, from the Ectoderm (in red below) develops the outer skin and nervous tissue. From the Mesoderm (in orange below) develops muscle, bone, cartilage, blood vessels and connective tissue. And the Endoderm layer (in yellow below) develops into the lining of the digestive and respiratory systems.

Although these cellular layers are also called germ layers, according to traditional medicine, they have nothing to do with germs. Dr. Hamer however, in his research, has determined that the organs derived from this ectoderm tissue uses viruses and certain bacteria when healing from a conflict. Organs derived from the mesoderm tissue use bacteria and sometimes fungi for healing, and the organs that originate from the endoderm tissue use TB bacteria and fungi for healing.

Dr. Hamer has also determined that these germs multiply at the time of a DHS and they do not cross the tissue layers. For example, in a lung cancer (death fright) you will never find a virus but instead TB bacteria. (The following is a diagram taken from Dr. Hamer’s book.)
