Study Notes
Origin of Mesenchyme
- Mesenchyme is derived from mesoderm.
Epithelial Tissue Function
- The main function of epithelial tissue is to form a barrier or lining in various body parts, such as skin, glands, and organs.
Characteristics of Covering Epithelium
- Covering epithelium is avascular, meaning it lacks blood vessels.
- Covering epithelium is innervated, meaning it receives nerve supply.
Germ Layer Derivatives
- Ectoderm is the germ layer that gives rise to the epidermis and nervous tissue.
Epithelial Cell Cohesion
- The main factor contributing to the cohesion of epithelial cells is cell adhesion molecules, such as cadherins and integrins.
