Question

Non-keratinised stratified epithelium occurs in
A. Vagina and cervix
B. Body cavity and anal cavity
C. Vagina, cervix and buccal cavity
D. Vagina, cervix, buccal cavity and anal cavity

Answer 1

Epithelium tissue is the tissue that covers the entire body surface. It is the outermost layer of the body. It is thin and protective layer of the body.

Complete Answer:
- Epithelial tissues cover the outer surfaces of organs and blood vessels of the body and the inner surfaces of cavities in many internal organs.
- Epithelial tissue is further three types: squamous, columnar, and cuboidal.
- Non-keratinised is the type stratified epithelium.
- This type of epithelial tissue is the tissues that cover the internal as well as external surfaces.
- According to their name they do not contain a special protein called keratin.
- The surface of non keratinized tissue made up of living cells.
- This epithelium forms present in the oesophagus, pharynx, buccal cavity, vagina, etc.

So, the correct answer is option D, Non-keratinised stratified epithelium occurs in Vagina, cervix, buccal cavity and anal cavity.

Additional information:
- Function of the epithelium tissue is secretion, absorption, transportation, protection, and receptor in taste and olfaction.
- Microvilli is the finger-like projection which is present on the epithelium cells.
- Cilia are the cytoplasm projections.

Note: Simple epithelium tissue has only one layer of cell which is different from stratified tissue that is multilayer. Non-keratinised stratified epithelium is type of stratified epithelium
