Which germ layer in embryonic development will form into the integumentary system and parts of the nervous system.

Question

BlackTom AI · Accepted Answer

The question asks which germ layer in embryonic development gives rise to the integumentary system and parts of the nervous system.
Option 1: mesoderm – This layer primarily forms the musculoskeletal system, cardiovascular system, and some connective tissues, not the skin or nervous tissue.
Option 2: ectoderm – This is the correct choice for the asked associations: the epidermis and its derivatives (hair, nails, glands) arise from the ectoderm, and the nervous system (including brain and spinal cord) also develops from this same layer.
Option 3: endoderm – This layer forms the lining of the gut and associated organs (such as the liver, pancreas, respiratory epithelium from foregut, etc.), not the skin or nervous system.
In summary, the ectoderm is the germ layer responsible for the integumentary system and significant portions of the nervous system, whereas mesoderm and endoderm contribute to other organ systems not primarily linked to skin or neural tissue.
