Examples of simple columnar in the following topics:

  • Types of Epithelial Tissue

    • The four major classes of simple epithelium are: 1) simple squamous; 2) simple cuboidal; 3) simple columnar; and 4) pseudostratified.
    • Simple columnar epithelium is a single row of tall, closely packed cells, aligned in a row.
    • These are simple columnar epithelial cells whose nuclei appear at different heights, giving the misleading (hence pseudo) impression that the epithelium is stratified when the cells are viewed in cross section.
    • Stratified epithelia can be columnar, cuboidal, or squamous type.
    • Columnar epithelium has cells taller than they are wide.
  • Epithelial Membranes

    • Most mucous membranes contain stratified squamous or simple columnar epithelial tissue.
  • Mucosa

    • The mucosa is the innermost layer of the gastrointestinal (GI) tract, composed of simple epithelium cells.
    • In the stomach the epithelium is simple columnar, and is organized into gastric pits and glands to deal with secretion.
  • Absorption in the Small Intestine

    • The inner wall, or mucosa, of the small intestine is lined with simple columnar epithelial tissue.
  • Skin and Mucosae (Surface Barriers)

    • In the stomach it is simple columnar, and is organised into gastric pits and glands to secrete acids and pepsin.
    • The small intestine epithelium is specialised for absorption; it is organised into simple columnar epithelium on protruding villi with narrow crypts, that have a high surface area.
  • Histology of the Large Intestine

    • The wall of the large intestine is lined with simple columnar epithelium.
  • Anatomy of the Large Intestine

    • The wall of the large intestine is lined with simple columnar epithelium.
  • Female Duct System

    • There are two types of cells within the simple columnar epithelium of the fallopian tube.
  • Bronchi and Subdivisions

    • The mucous membrane lining the bronchi also undergoes a transition from ciliated pseudostratified columnar epithelium to simple cuboidal epithelium to simple squamous epithelium further into the lung.
  • Trachea

    • It is lined with pseudostratified ciliated columnar epithelium cells with goblet cells that produce mucus.
    • The cartilage of the trachea is considered hylaine cartilage, which is simple, transparent, and made primarily of collagen.
