Neuronal ectoderm
Cells of the nervous system differentiate from the ectoderm germ layer during embryonic development. The ectoderm gives rise to not only the nervous system, but also to structures such as the skin and hair.
A thermophile is a type of organism that thrives in high temperature environments. They can be found in various germ layers depending on the specific organism. For example, thermophilic bacteria can be found in the mesoderm layer, as they are commonly found in soil, while thermophilic archaea can be found in the endoderm layer, as they are often found in extreme environments like hydrothermal vents.
Germ layer development in embryos begins with gastrulation, the process by which a blastula reorganizes into a gastrula with distinct germ layers (ectoderm, mesoderm, and endoderm). During gastrulation, cells migrate and differentiate to form these primary germ layers, setting the foundation for future tissue and organ development.
Connective tissues primarily develop from the mesoderm germ layer. The mesoderm gives rise to various connective tissue types, including bone, cartilage, blood, and adipose tissue. Some connective tissues, like those found in the head, may also have contributions from the ectoderm and neural crest cells, but the mesoderm is the principal source for most connective tissues in the body.
Muscle tissues are derived from the mesodermal layer of the embryonic germ cells through a process called myogenesis.
All nervous tissue arise from ectoderm. Whether central or peripheral. It is anatomical division. Functionally all nervous cells are connected to each other.
The embryo layer that forms the skin and nervous tissue is the ectoderm. It gives rise to the epidermis of the skin, hair, nails, and the nervous system including the brain and spinal cord. The ectoderm is one of the three primary germ layers that develop during gastrulation in embryogenesis.
The ectoderm.
Cells of the nervous system differentiate from the ectoderm germ layer during embryonic development. The ectoderm gives rise to not only the nervous system, but also to structures such as the skin and hair.
This occurs as a result of the folding of ectoderm tissue. The ectoderm is a type of germ cell layer present in a young embryo.
A thermophile is a type of organism that thrives in high temperature environments. They can be found in various germ layers depending on the specific organism. For example, thermophilic bacteria can be found in the mesoderm layer, as they are commonly found in soil, while thermophilic archaea can be found in the endoderm layer, as they are often found in extreme environments like hydrothermal vents.

Endoderm: (most internal germ layer) gives rise to the lining of the digestive tract and the organs derived from it, such as the liver and lungs of vertebrates.Mesoderm: (middle germ layer) forms muscle, the skeletal system, and the circulatory system.Ectoderm: (most exterior germ layer) gives rise to the outer covering and, in some phyla, to the central nervous system.

Gastrulation is first step towards germ layer development .
Neural tissue is formed by neural stem cells, which are progenitor cells found in the nervous system. These stem cells have the ability to differentiate into various types of neural cells like neurons, astrocytes, and oligodendrocytes, ultimately forming the intricate network of the nervous system.
