Verified step by step guidance

Understand the three primary germ layers formed during early embryonic development: ectoderm, mesoderm, and endoderm.

Identify the structures derived from each germ layer. The ectoderm primarily forms the nervous system and the epidermis of the skin.

Recognize that the mesoderm is responsible for forming structures such as muscles, bones, the cardiovascular system, and connective tissues.

Note that the endoderm gives rise to internal structures like the liver and pancreas, as well as the lining of the digestive and respiratory systems.

Conclude that muscles and bones are derived from the mesoderm, as opposed to the nervous system, liver, pancreas, or epidermis, which are derived from other germ layers.
