  • Function of bone tissue

    Supports and protects the body and stores calcium.

  • Function of dense regular connective tissue

    Forms tendons and ligaments, providing strong attachment.

  • Function of adipose tissue

    Supports and protects, insulates against heat loss, and serves as a reserve source of fuel.

  • Function of fibrocartilage

    Provides tensile strength and absorbs compressive shock.

  • Unique feature of blood as connective tissue

    Composed of cells in a fluid matrix (plasma).

  • Epithelial membrane lining closed ventral body cavities

    Serous membrane lines closed ventral cavities like pleura and pericardium.

  • Epithelial membrane lining body cavities open to the exterior

    Mucous membrane lines digestive and respiratory tracts.

  • Characteristics of cutaneous membrane

    Consists of keratinized stratified squamous epithelium forming the skin.

  • Membrane lining blood vessels and heart

    Endothelium membrane lines cardiovascular organs.

  • Primary blast cell for connective tissue proper

    Fibroblast is the main precursor cell.

  • Modification of simple columnar epithelium for absorption

    Dense microvilli increase surface area for absorption in the digestive tract.

  • Tissue type with lacunae, calcium salts, and blood vessels

    Bone (osseous tissue) contains these features.

  • Cell type not found in areolar connective tissue

    Chondrocyte is absent in areolar tissue.

  • Fiber type providing tensile strength in connective tissue

    Collagen fibers give great tensile strength.

  • Definition of tissue

    Groups of cells similar in structure performing a common function.

  • Cartilage type maintaining external ear shape

    Elastic cartilage maintains ear shape.

  • Classification of glands secreting directly into blood

    Endocrine glands secrete hormones into the bloodstream.

  • Characteristic of pseudostratified ciliated columnar epithelium

    Lines most of the respiratory tract and contains mucus-secreting goblet cells.

  • Connective tissue extracellular matrix components

    Composed of fibers and ground substance.

  • Difference between epithelial and connective tissue

    Epithelial tissue is avascular and covers surfaces, while connective tissue is vascular and supports.

  • Layers of the epidermis responsible for cell division

    Stratum basale contains mitotically active cells.

  • Function of keratin in the epidermis

    Toughens the skin and provides a protective barrier.

  • Role of dendritic cells in the skin

    Act as immune system activators by detecting pathogens.

  • Function of arrector pili muscle

    Pulls hair follicles upright causing goosebumps.

  • Primary function of sudoriferous glands

    Thermoregulation through sweat secretion.

  • Reason hypodermis acts as shock absorber

    Contains adipose tissue that cushions underlying structures.

  • Most important risk factor for skin cancer

    Overexposure to UV radiation is the main risk.

  • Function of melanocytes and keratinocytes in UV protection

    Keratinocytes accumulate melanin granules from melanocytes to form a UV-blocking layer.

  • Homeostasis example involving skin and UV damage

    Keratinocytes release signals to increase melanin production after UV exposure.
