Labeling of Epithelial Tissues Flashcards

Study Notes

Epithelial Tissue Concepts

Basement Membrane: A thin, fibrous layer that separates epithelial tissues from underlying connective tissues, providing support and anchorage.
Simple Cuboidal Epithelium: Composed of a single layer of cube-shaped cells; it functions in secretion and absorption, commonly found in kidney tubules and glands.
Pseudostratified Ciliated Columnar Epithelium: Appears to be stratified but is not; consists of varying cell heights with cilia on top. Primarily found in respiratory tracts, facilitating the movement of mucus.
Cilia: Microscopic, hair-like structures on the surface of certain epithelial cells; aid in the movement of substances across the epithelial surface, especially in respiratory pathways.
Cytoplasm: The gel-like substance within cells, excluding the nucleus, where cellular processes and metabolic activities occur.
Nuclei: The plural form of nucleus; contains cell's genetic material and controls cellular activities including growth and reproduction.
Relaxed Epithelium: Refers to the state of certain epithelial tissues, like transitional epithelium, when not stretched; typically has a more rounded cell appearance.
Stretched Epithelium: Describes epithelial tissues, particularly transitional epithelium, in an extended state; cells become flattened to accommodate stretching, as seen in the urinary bladder.
Nucleus: The membrane-bound organelle that houses DNA; essential for directing cellular activities and maintaining cellular integrity.
Cell Boundaries: Refers to the definable outer layer of a cell, composed of the plasma membrane, which regulates the movement of substances in and out.
Simple Columnar Epithelium: Comprises a single layer of tall, column-like cells; specialized for absorption and secretion; found in the digestive tract and uterine lining.
Goblet Cell: Specialized epithelial cell that secretes mucus; plays a vital role in protecting and lubricating the epithelial surface, particularly in the respiratory and intestinal tracts.
