Cuboidal epithelial

Definition

Cuboidal epithelial cells are a type of epithelial tissue characterized by their cube-like shape and central, spherical nuclei. They are typically found in glands, ducts, and portions of the kidney tubules where they function in secretion and absorption.

5 Must Know Facts For Your Next Test

1. Cuboidal epithelial cells have a square or cube shape when viewed in cross-section.
2. These cells are commonly found lining the ducts of glands such as salivary glands, thyroid gland, and pancreas.
3. They play an essential role in both secretion (e.g., enzymes, hormones) and absorption (e.g., nutrients).
4. The nuclei of cuboidal epithelial cells are large, spherical, and centrally located.
5. Simple cuboidal epithelium consists of a single layer of these cells whereas stratified cuboidal epithelium has multiple layers.
