Detailed explanation-1: -The neural tissue which includes the brain, spinal cord, nerve cells and neuroglia, is derived from the ectoderm, which is the external germ layer. The ectoderm also forms the epithelial tissues of the skin and linings of mouth, anus, nostrils, hair and nails.

Detailed explanation-2: -It is the outermost layer, and is superficial to the mesoderm (the middle layer) and endoderm (the innermost layer). It emerges and originates from the outer layer of germ cells. The word ectoderm comes from the Greek ektos meaning “outside", and derma meaning “skin". Organs derived from ectoderm.

Detailed explanation-3: -As organs form, a process called organogenesis, mesoderm interacts with endoderm and ectoderm to give rise to the digestive tract, the heart and skeletal muscles, red blood cells, and the tubules of the kidneys, as well as a type of connective tissue called mesenchyme.
