    The sulcular epithelium:

    • Is nonkeratinized.

    • Is keratinized.

    • Has thick epithelial layer.

    • Has long epithelial ridges.

    Correct Answer
    A. Is nonkeratinized.
    Explanation
    The sulcular epithelium refers to the epithelial lining of the gingival sulcus, which is the space between the tooth surface and the gum tissue. This epithelium is nonkeratinized, meaning it lacks a tough outer layer of keratin. Instead, it has a thin, delicate structure that is more susceptible to damage and infection. This nonkeratinized nature allows for easier exchange of fluids and cells between the gingival sulcus and the underlying connective tissue.

    Keratohyalin granules are present in:

    • Granular layer and prickle cell layer

    • Basal layer and prickle cell layer

    • Cornified layer

    • Basement membrane

    Correct Answer
    A. Granular layer and prickle cell layer
    Explanation
    Keratohyalin granules are present in the granular layer and prickle cell layer of the skin. The granular layer is the layer of the epidermis where keratinocytes start to produce keratin and undergo changes in their shape and composition. The prickle cell layer is located just above the granular layer and consists of keratinocytes that are connected by desmosomes, giving them a spiky appearance. Keratohyalin granules play a role in the formation of the skin's barrier function by contributing to the production of keratin and the aggregation of keratin filaments.

    Granulomas are a type of immune response characterized by the accumulation of immune cells. Lymphocytes are the most frequently found cells in granulomas because they play a crucial role in the immune system's response to infections and foreign substances. Lymphocytes, specifically T-cells and B-cells, are responsible for recognizing and targeting antigens, initiating an immune response, and coordinating the actions of other immune cells. Therefore, their high presence in granulomas is indicative of an ongoing immune reaction. Mast cells, giant cells, and neutrophils may also be present in granulomas, but lymphocytes are the most common.
