Simple Cuboidal Epithelium
This simple type consists of a single layer of cube-like cells that are as tall as they are wide. The nucleus is usually spherical, giving the cells a uniform appearance, and all the cells are directly attached to the basement membrane. They are usually found in places that are secretory and absorptive. The large cube shape provides the proper surface area for these activities.
Examples of Simple Cuboidal Epithelium
The following are examples of where simple cuboidal epithelium is found:
- Kidney Tubules: In the kidneys, simple cuboidal epithelium is essential for the absorption and secretion processes in the renal tubules. These cells help in blood filtration and purify the blood, playing an important role in urine formation.
- Glands and Ducts: This epithelium lines the surfaces of the ducts of many glands like the salivary, thyroid, and pancreas, and it is involved in the production of various substances. For example, the thyroid gland is involved in the production of thyroid hormones. It’s also found on the surface of the ovaries, where it’s involved in the formation of egg cells.
Cuboidal Epithelium – Types Diagram, and Functions
The Cuboidal Epithelium is one of the types of epithelial tissue. The specific feature of this tissue is that all the cells are cuboid in shape. The main functions of epithelial tissue are protection, secretion, and absorption. The cuboidal epithelium is found in the linings of the ovaries, kidneys, salivary glands, and other large glands. The cuboidal epithelium is divided into various types according to its number of layers and structure.
In this article, we will study what cuboidal epithelium is, the types and locations of cuboidal epithelium, simple cuboidal epithelium, stratified cuboidal epithelium, and the specialized variants and functions of cuboidal epithelium.
