Study Notes
Germ Layers and Organ Development
- Three primary germ layers — ectoderm, mesoderm, and endoderm — give rise to all tissues and organs in the body.
- Ectoderm: Forms nervous tissue, including the brain, spinal cord, and peripheral nerves. It also differentiates into the epidermis (outer layer) of the skin.
- Mesoderm: This layer develops into cartilage, bone, and other connective tissues. It also generates blood vessels, lymphatic vessels, and the lining epithelium of the gonads.
- Endoderm: The endoderm gives rise to the lining epithelium of the digestive tract, respiratory system, and the epithelial components of the thyroid gland, liver, pancreas, and bladder.
