  • 2. 

    Blood vessels penetrate the basement membrane.  True or false?

    • True

    • False

    Correct Answer
    A. False
    Explanation

    Together the microvilli and the glycocalyax proteins form the ______ border of the intestinal epithelium.

    Correct Answer
    brush
    Explanation
    The microvilli and glycocalyax proteins work together to form the brush border of the intestinal epithelium. The brush border is a specialized structure consisting of tiny finger-like projections called microvilli, which increase the surface area of the intestinal lining for better absorption of nutrients. The glycocalyax proteins are located on the surface of the microvilli and help protect and lubricate the epithelial cells. Together, they create the brush border, which is essential for the proper functioning of the intestinal epithelium.

    The basement membrane attaches epithelial cells to underlying connective tissue.  What is a common component this basement membrane?

    Correct Answer
    collagen
    Explanation
    The basement membrane is a thin layer of extracellular matrix that separates the epithelial cells from the connective tissue. It provides structural support and helps in the attachment of epithelial cells to the underlying tissue. Collagen is a common component of the basement membrane, as it is a major structural protein that gives strength and stability to tissues. Collagen fibers in the basement membrane contribute to its integrity and play a crucial role in maintaining the structural integrity of the epithelial tissue.

    Which of the following choice(s) derive from the ectoderm?

    • Epidermis

    • Adrenal Medula

    • Adrenal Cortex

    • Thymus

    Correct Answer(s)
    A. Epidermis
    A. Adrenal Medula
    Explanation
    The ectoderm is one of the three primary germ layers that develop during embryogenesis. It gives rise to various structures including the epidermis, which is the outermost layer of the skin. The adrenal medulla, which is responsible for producing adrenaline and noradrenaline, also derives from the ectoderm. Therefore, both the epidermis and adrenal medulla are correct choices that derive from the ectoderm.
