Verified step by step guidance

Understand the concept of embryonic layers: During embryonic development, three primary germ layers form, which are the ectoderm, mesoderm, and endoderm. Each layer gives rise to different tissues and organs in the body.

Identify the function of the ectoderm: The ectoderm is the outermost layer of the embryo. It is responsible for forming the nervous system, including the brain and spinal cord, as well as some epithelial tissues such as the skin.

Differentiate between the layers: The endoderm forms the innermost layer and gives rise to the lining of the digestive and respiratory systems. The mesoderm forms the middle layer and develops into muscles, bones, and the circulatory system.

Recognize the role of the ectoderm in tissue development: The ectoderm is crucial for the development of the nervous tissue, which includes neurons and glial cells, and some epithelial tissues like the epidermis.

Conclude with the correct answer: Based on the functions of the embryonic layers, the ectoderm is the layer that gives rise to nervous tissue and some epithelial tissue.
