Epithelial tissue rests on an extracellular basement membrane
The functions of basement membrane
- The basement membrane is a skinny non-cellular fibrous membrane on which epithelial tissues rest. It also separates the tissue from the underlying tissues.
- The basement membrane is the fusion of two laminae.
- The basement membrane lies between the epidermis or outer layer of skin, and the dermis, the middle layer of skin, keeping them tightly connected.
- Basement membrane, also referred to as basal laminae, are extracellular sheets of proteins that surround tissues, providing structural support, a filtration function, and a surface for cell attachment, migration, and differentiation.
