GENERAL HISTOLOGY

Detailed explanation-1: -Columnar epithelial cells are taller than they are wide: they resemble a stack of columns in an epithelial layer. They are most-commonly found in a single-layer arrangement. The nuclei of columnar epithelial cells in the digestive tract appear to be lined up at the base of the cells.

Detailed explanation-2: -If the cells are taller than they are wide, then they are called columnar. Cuboidal and columnar cells are usually involved in secretion and/or absorption and need more cytoplasmic volume to accommodate the organelles needed for these activities.

Detailed explanation-3: -Simple columnar epithelium is a single layer of columnar epithelial cells which are tall and slender with oval-shaped nuclei located in the basal region, attached to the basement membrane. In humans, simple columnar epithelium lines most organs of the digestive tract including the stomach, and intestines.

Detailed explanation-4: -Columnar epithelium: Columnar epithelial cells are column-like in appearance, meaning they are taller than they are wide.

Detailed explanation-5: -This is a single layer of mucus-producing, tall epithelium that extends between the endometrium and the cervical squamous epithelium. Columnar epithelium appears irregular, with stromal papillae and clefts.
