Nervous tissue is derived from the ectoderm germ layer during embryonic development.
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.
The skin is derived from the ectoderm germ layer during embryonic development. The ectoderm gives rise to the outermost layer of the skin, called the epidermis, as well as structures such as hair, nails, and certain glands.
The endoderm and ectoderm
Nervous tissue is derived from the ectoderm germ layer during embryonic development.
Ectoderm
All nervous tissue arise from ectoderm. Whether central or peripheral. It is anatomical division. Functionally all nervous cells are connected to each other.
From inner to outer, the germ cell layers are the endoderm, mesoderm, and ectoderm. Each of the three layers develops into a different part of the embryo: the endoderm into the respiratory, auditory, and digestive system; the mesoderm into the skeleton and muscles; and the ectoderm into the skin, tooth enamel, and nervous system.
ectoderm is the young epidermis, same with endoderm, it is the young gastrodermis.
Ectoderm, endoderm, and mesoderm can produce epithelial tissues

The pigmented layer of the eye is called the uvea.
Melanocytes are derived from the neural crest, which is a transient embryonic structure that forms from the ectoderm germ layer.
Endoderm
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.
