Study Notes

Epithelium

Epithelium is derived from three embryological germ layers: ectoderm, endoderm, and mesoderm
Ectoderm gives rise to the epidermis of the skin and nervous tissue.
Endoderm lines the intestine
Mesoderm gives rise to non-specialized connective tissues, cartilage, and blood.

Tissues Differentiation

Tissues differentiate during embryonic development from the three primitive germ layers
The epidermis and dermis are distinct, with the epidermis being part of epithelial tissue.
