    Study Notes

    Reticular Fibers

    • Thin collagenous fibers that form supportive networks in tissues.
    • Similar to collagen but specifically designed for forming networks.

    Types of Connective Tissue

    • Loose Connective Tissue

      • Composed of fewer protein fibers, creating a lacy network.
      • Areolar Tissue: Delicate membranes binding skin to underlying organs, consisting of fibroblasts in a gel-like ground substance with collagenous and elastic fibers.
      • Adipose Tissue: Stores fat beneath skin, around joints, and padding organs, insulating the body and housing fat cells.
      • Reticular Tissue: Contains only reticular fibers, providing support for certain structures.

    • Dense Connective Tissue

      • Composed of densely packed collagenous fibers, very strong with poor blood supply.
      • Regular Dense Connective Tissue: Collagen fibers in parallel bundles, forms tendons and ligaments.
      • Irregular Dense Connective Tissue: Randomly arranged collagen fibers, providing resistance in multiple directions, forms capsules and the dermis layer of skin.
      • Elastic Dense Connective Tissue: Similar to regular but more elastic.

    Specialized Connective Tissue

    • Cartilage:

      • Rigid tissue providing supportive framework, lacks vascular system leading to slow healing.
      • Contains chondrocytes in lacunae, performing various metabolic and structural tasks.

    • Satellite Cells:

      • A type of glial cell in the peripheral nervous system located in sensory and autonomic ganglia.

    • Schwann Cells:

      • Glial cells surrounding peripheral neurons, essential for maintenance, function, and regeneration.

    Membranes

    • Tissue Membrane: A thin layer covering structures or lining cavities.
    • Body Membranes: Cover surfaces and line cavities, providing protection and lubrication.
      • Epithelial Membranes: Includes cutaneous, mucous, and serous membranes.
        • Cutaneous Membrane: Composed of epidermis and dermis, is exposed and dry.
        • Mucous Membrane: Lines cavities opening to the outside, consists of various epithelial types overlying loose connective tissue, secretes mucus for protection and absorption.
        • Serous Membrane: Lines internal cavities, composed of simple squamous epithelium and secretes serous fluid for lubrication.

    Glands

    • Thyroid Gland: Located in the neck, regulates metabolism and tissue function through hormones.
    • Pituitary Gland: Master gland controlled by the hypothalamus, regulates other glands including thyroid and adrenal glands.
    • Hypothalamus: Communication center regulating temperature, food intake, sleep, and emotional behavior.
    • Pineal Gland: Deep in the brain, regulates melatonin for sleep patterns and female hormones.
    • Adrenal Gland: Located atop kidneys, produces hormones like cortisol and adrenaline that control blood pressure and stress response.
    • Pancreas: Dual-function gland producing digestive enzymes and hormones for blood glucose regulation. Inflammation of pancreas is called pancreatitis.
    • Sweat Glands: Two types, eccrine (regulating body temperature) and apocrine (associated with hair follicles and stress).
    • Sebaceous Glands: Secrete sebum for skin lubrication, aiding temperature regulation and moisture retention.
    • Salivary Glands: Produce saliva for digestion and oral health.
    • Mammary Glands: Type of sweat gland responsible for milk production in females, triggered by hormones during pregnancy.

    Inflammatory Response

    • A defense mechanism mobilizing immune cells to isolate and destroy pathogens, facilitating tissue repair.
    • Stages of Inflammatory Response:
      • Chemical Mediators Released: Damaged tissue releases mediators causing blood vessel changes.
      • Tissue Swelling: Increased blood flow and capillary permeability lead to swelling.
      • Recruitment of Immune Cells: White blood cells migrate to infection site to eliminate pathogens.

    Symptoms of Inflammation

    • Redness
    • Heat
    • Swelling
    • Pain
    • Disturbed Function

    Cardinal Signs of Inflammation

    • Rubor (Redness): Increased blood flow.
    • Tumor (Swelling): Fluid exudation from tissues.
    • Calor (Heat): Increased blood flow and fluid exudation due to inflammatory mediators.
