  • What are the main functions of epithelial tissue?

    Protection, absorption, filtration, secretion, and sensory reception.

  • Name the three shapes of epithelial cells.

    Squamous (flat), cuboidal (cube-shaped), and columnar (tall and column-like).

  • What distinguishes simple epithelium from stratified epithelium?

    Simple epithelium has one cell layer; stratified epithelium has multiple layers.

  • Describe the function of connective tissue.

    Supports, binds, protects, insulates, and transports substances within the body.

  • What are the three main components of connective tissue?

    Cells, fibers, and ground substance (extracellular matrix).

  • Name the three types of fibers found in connective tissue.

    Collagen (strength), elastic (stretch), and reticular (support network).

  • What is the difference between loose and dense connective tissue?

    Loose connective tissue has more ground substance and fewer fibers; dense connective tissue has more fibers and less ground substance.

  • Give an example of loose connective tissue.

    Areolar tissue, which cushions organs and holds tissue fluids.

  • What type of connective tissue stores fat?

    Adipose tissue stores energy and insulates the body.

  • What is the primary cell type in cartilage?

    Chondrocytes embedded in a firm matrix.

  • Name the three types of cartilage.

    Hyaline, elastic, and fibrocartilage.

  • What connective tissue type connects muscles to bones?

    Tendons, composed of dense regular connective tissue.

  • What connective tissue connects bones to bones?

    Ligaments, made of dense regular connective tissue.

  • Describe the structure of simple squamous epithelium.

    Single layer of flat cells allowing rapid diffusion and filtration.

  • Where is pseudostratified columnar epithelium commonly found?

    In the respiratory tract, often with cilia and goblet cells.

  • What is the function of transitional epithelium?

    Allows stretching and recoiling, found in the urinary bladder.

  • What type of connective tissue forms the framework of lymphoid organs?

    Reticular connective tissue.

  • What is the ground substance in connective tissue?

    A gel-like material that fills space between cells and fibers, facilitating nutrient and waste exchange.

  • What type of connective tissue is blood classified as?

    Connective tissue with a liquid matrix called plasma.

  • What is the role of fibroblasts in connective tissue?

    They produce fibers and ground substance of the extracellular matrix.
