Verified step by step guidance

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

Review the role of the mesoderm: The mesoderm is the middle germ layer and is responsible for forming structures such as muscle tissue, bones, the cardiovascular system, and connective tissues.

Differentiate the other germ layers: The ectoderm forms the outermost layer and gives rise to the nervous system, skin, and sensory organs. The endoderm forms the innermost layer and develops into the lining of the digestive and respiratory tracts, as well as associated organs.

Clarify the neural crest: The neural crest is a specialized group of cells derived from the ectoderm. It contributes to the formation of certain structures like peripheral nerves, melanocytes, and facial cartilage, but not muscle tissue.

Conclude that muscle tissue arises specifically from the mesoderm, as it is the germ layer responsible for developing the musculoskeletal system and related structures.
