GENERAL HISTOLOGY

Detailed explanation-1: -Stratified columnar epithelium is a rare type of epithelial tissue composed of column-shaped cells arranged in multiple layers. It is found in the conjunctiva, pharynx, anus, and male urethra. It also occurs in embryo.

Detailed explanation-2: -Columnar epithelial cells are long and thin, like columns. These are usually found in places that secrete mucus such as the stomach. They can also specialize to receive sensory information in places like taste buds on your tongue and inside of your nose.

Detailed explanation-3: -Examples of columnar epithelia are Goblet cells, those lining the pharynx, sex organs, respiratory tract, fallopian tubes, etc.

Detailed explanation-4: -Simple columnar epithelium consists of one layer of cells that are taller than they are wide and look like closely packed, slender columns. Bases of cells rest on abasement membrane; apical surfaces contact a lumen. The ovoid nucleus is centrally or basally placed.

Detailed explanation-5: -Simple columnar epithelial cells are some of the most prolific cells in the body, mainly because they can fulfill so many functions. They are found throughout the body’s organ system, including the digestive tract and the female reproductive system. They are found in the respiratory system, including the nasal passage.
