Study Notes
Simple Columnar Epithelium
- Characterized by a single layer of cells that are longer than they are wide, with the nucleus located near the basement membrane.
- Can be ciliated or non-ciliated.
- Performs three main functions: absorption, secretion, and protection.
- Found in the linings of specific organs, including the uterus, uterine tube, stomach, and intestine.
Structure
- Nuclei of individual cells are visible in a cross-section of the tissue.
- The apical surface of simple columnar epithelium in the digestive tract features a distinct surface, nuclei, and basement membrane.
Learn about the characteristics, functions, and locations of simple columnar epithelium, a type of epithelial tissue. Understand its structure, including the location of nuclei, and its roles in absorption, secretion, and protection.
