    Study Notes

    Connective Tissue

    • Bone is the most rigid type of connective tissue
    • Adipose connective tissue stores fat for energy and insulation
    • Areolar connective tissue is found in the subcutaneous layer of skin
    • Reticular connective tissue has a delicate network of reticular fibers associated with reticular cells, found in the spleen and lymph nodes
    • Collagen fibers are present in connective tissues to provide structure and support

    Muscle Tissue

    • Smooth muscle has the ability to contract involuntarily
    • Smooth muscle has spindle-shaped cells with a single nucleus
    • Skeletal muscle is responsible for voluntary movement of bones
    • Cardiac muscle is found only in the heart, and its cells are branched and interconnected

    Epithelial Tissue

    • Simple squamous epithelium is a single layer resting on a basement membrane, resembles floor tiles
    • Epithelial tissue functions as a protective barrier, for absorption and secretion
    • Stratified epithelial tissue has multiple layers of cells
    • Epithelial tissue is avascular and receives nutrients by diffusion
    • Epithelial tissue has a free surface exposed to the body's exterior or internal organ cavity

    Other

    • Tendons are a type of connective tissue that attaches skeletal muscles to bones
    • Fibrinogen is a soluble protein that plays a crucial role in blood clotting
