Question

Explain how the different germ layers give rise to different tissue types.

a) Ectoderm forms the nervous system and skin, endoderm develops into the lining of internal organs, and mesoderm gives rise to muscles, bones, and connective tissues.
b) Ectoderm gives rise to the digestive system, endoderm forms the skin, and mesoderm develops into the circulatory system.
c) Ectoderm forms the circulatory system, endoderm gives rise to the nervous system, and mesoderm develops into the musculoskeletal system.
d) Ectoderm forms muscles, endoderm develops the nervous system, and mesoderm gives rise to the skin.

Answer 1

The ectoderm forms the nervous system and skin, the mesoderm develops into muscles, bones, and the circulatory system, and the endoderm gives rise to internal lining organs like the digestive and respiratory systems.

Step-by-step explanation:

The different germ layers, which are the endoderm, the ectoderm, and the mesoderm, differentiate to form various tissue types and organs in the body. The ectoderm forms the nervous system, skin, and related structures like hair and nails. The mesoderm develops into muscles, bones, connective tissues, the heart, blood vessels, and kidneys. The endoderm gives rise to the lining of internal organs such as the digestive system, liver, pancreas, and the respiratory tracts like the trachea and lungs.
