Question

Which type of tissue is skin?

Answer 1

Skin:

1. The skin is the largest organ and is a type of epithelial tissue.
2. Epithelial tissue is formed from a tightly fitted continuous layer of cells.
3. One surface of the epithelial tissue is exposed to either the external environment or the body fluid.
4. The other surface is attached to tissue by a membrane, which consists of fibres and polysaccharides secreted by epithelial cells.
5. There are specialised junctions present between the cells of the epithelium, that link individual cells.
6. The junctions are:

1. Tight junctions- They prevent leakage across tissues
2. Adhering junctions- They keep the neighbouring tissues well cemented together
3. Gap junctions- They facilitate the movement of ions and molecules across the tissue.
