Verified step by step guidance

Understand the three primary germ layers in embryonic development: ectoderm, mesoderm, and endoderm. Each layer gives rise to specific structures in the body.

Recall that the ectoderm primarily forms structures such as the epidermis of the skin, nervous system, and sensory organs.

Remember that the mesoderm develops into structures like bones, skeletal muscles, the cardiovascular system, and connective tissues.

Focus on the endoderm, which is responsible for forming the lining of internal organs, including the digestive tract, respiratory tract, and associated glands.

Match the options provided in the question to the germ layers: The lining of the digestive tract is derived from the endoderm, while the epidermis of the skin (ectoderm), bones of the limbs (mesoderm), and skeletal muscles (mesoderm) are not.
