    Study Notes

    Tissues of the Body

    • A tissue is a group of cells with similar morphological characteristics, specialized to perform specific functions.
    • There are 4 basic tissues in the body: epithelial, connective, muscular, and nervous tissue.

    Epithelial Tissue

    • Epithelial tissue forms continuous sheets of cells that line internal cavities and cover the external surfaces of the body.
    • General characteristics of epithelial tissue:
      • Cells are tightly joined together.
      • Cell boundaries are ill-defined.
      • Cells rest on a basement membrane.
      • Originate from the three germ layers: ectoderm, mesoderm, and endoderm.
      • Avascular but highly innervated.
      • Cells can regenerate.
      • Can modify to form other types (glandular epithelium, neuro-epithelium, and myo-epithelium).

    Classification of Epithelial Tissue

    • Surface Epithelium: covers surfaces of the body or lines luminal cavities within the body.
    • Types of epithelial tissue:
      • Simple epithelium: one layer of cells.
      • Stratified epithelium: more than one layer of cells.
      • Squamous epithelium: flat, plate-like cells.
      • Squamous keratinized epithelium: found in skin.
      • Transitional epithelium: found in urinary tract.
      • Glandular epithelium: forms glands.
      • Neuro-epithelium: forms sensory receptors.
      • Myo-epithelium: found in exocrine glands.
      • Columnar epithelium: tall, column-like cells.
      • Cuboidal epithelium: cube-like cells.
      • Pseudo-stratified columnar epithelium: appears multi-layered but is not.
      • Ciliated epithelium: has hair-like structures.
      • Pseudo-stratified columnar epithelium with goblet cells: found in respiratory tract.
      • Respiratory epithelium: lines the upper respiratory tract (nasal cavity, trachea, and bronchi).
      • Simple squamous epithelium: lines blood vessels.
      • Simple columnar epithelium: lines the digestive tract.
      • Simple cuboidal epithelium: lines the kidneys and adrenal glands.
      • Pseudostratified columnar epithelium: lines the respiratory tract.
