Kuutiopiteelissä

Kuutiopiteelissä is a Finnish term referring to cuboidal epithelium. This type of epithelial tissue is characterized by cells that are roughly cube-shaped, with a height and width that are approximately equal. The nucleus of a cuboidal cell is typically spherical and located centrally within the cell.

This tissue is found in various locations throughout the body, where it plays a role in secretion and absorption. Examples include the ducts of glands, such as salivary glands and sweat glands, and the kidney tubules. In these locations, the cuboidal cells are responsible for actively transporting substances, either into or out of the body or into the bloodstream.

The structure of cuboidal epithelium provides a balance between surface area for transport and structural integrity. While not as extensive as the surface area offered by simple squamous epithelium, it is sufficient for the metabolic needs of the tissues where it is found. The presence of organelles within the cytoplasm, such as mitochondria, supports the energy-intensive processes of active transport. Kuutiopiteelissä can be found as simple cuboidal epithelium, consisting of a single layer of cells, or stratified cuboidal epithelium, which has multiple layers. Stratified cuboidal epithelium is less common and provides greater protection.
