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.

  • Epithelial Tissues

    • Columnar epithelial cells lining the respiratory tract appear to be stratified.
    • However, each cell is attached to the base membrane of the tissue and, therefore, they are simple tissues.
    • This is called pseudostratified, columnar epithelia .
    • Simple columnar epithelial cells absorb material from the digestive tract.
    • Pseudostratified columnar epithelia line the respiratory tract.

  • Anatomy of the Large Intestine

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

  • Histology of the Large Intestine

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

  • The Propylaea and the Erechtheion

    • The order of the Propylaia and its columns are Doric and the decoration of is plain and simple; there are no reliefs carved into the metopes and the pediment is unadorned.
    • The women replace columns, yet look columnar themselves.
    • The sculpted columnar form of the caryatids is named after the women of the town of Kayrai, a small town near and allied to Sparta.

  • 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.
