What is Stratified Cuboidal Epithelium? (with pictures).
Cuboidal epithelium definition, epithelium consisting of one or more layers of cells of cuboid or polyhedral shape. See more.
There are two types of cuboidal epithelium, namely: a) Simple cuboidal epithelium, which is basically a single layer of cuboidal cells, with some cells having microvilli (e.g. in kidney tubules) or cilia (e.g. in terminal bronchioles). They can be.

The simple cuboidal epithelium is found, e.g., in kidney tubules and seminiferous tubules as well as in glandular excretory ducts and as retinal pigment epithelium and lens epithelium in the eye. They have large cytoplasmic content so, they perform important complex functions like absorption and secretion. They are found in exocrine glands, endocrine glands, and ducts of endocrine glands.
Types of stratified squamous epithelia. There are two main types of stratified squamous epithelium which are the non-keratinized and keratinized. When the surface of the epithelium remains moist with the most superficial squamous cells having nuclei and are living cells, then such type is referred to as non-keratinized stratified squamous epithelium but when the most superficial squamous cells.
Simple cuboidal epithelium. S imple cuboidal epithelium is a layer of cube-like shape cells, i.e are as wide as tall. This can be observed when they are cut perpendicularly to the epithelial surface. The nucleus is rounded and located centrally or slightly basal in the cell. Sometimes, the apical surface of the cell shows cilia or flagella. This type of epithelium lines many ducts and tubes.
Pseudostratified In some columnar epithelia, the cells become so crowded that some of the nuclei become displaced and several rows of nuclei appear in sections of the cell sheet, even though each cell is still attached to the basement membrane. In these cases, it is difficult to trace the continuity of different cells from base to apex and the epithelium may appear stratified even though it.
