Termini in questo insieme (15)

  • What are epithelial tissue cells?

    Epithelial tissue cells cover body surfaces and line cavities. They protect, absorb, secrete, and filter substances.

  • What characterizes connective tissue cells?

    Connective tissue cells support and bind other tissues. They include fibroblasts, adipocytes, and macrophages.

  • What is the main function of muscle tissue cells?

    Muscle tissue cells contract to produce movement. Types include skeletal, cardiac, and smooth muscle cells.

  • What are the key features of nervous tissue cells?

    Nervous tissue cells transmit electrical signals. They include neurons and supporting glial cells.

  • What type of epithelial cells are flat and scale-like?

    Squamous epithelial cells are flat and thin, allowing for easy diffusion and filtration.

  • Which epithelial cells are cube-shaped?

    Cuboidal epithelial cells are cube-shaped and often involved in secretion and absorption.

  • Describe columnar epithelial cells.

    Columnar epithelial cells are tall and column-shaped, specialized for absorption and secretion.

  • What are fibroblasts?

    Fibroblasts are connective tissue cells that produce collagen and extracellular matrix.

  • What role do adipocytes play?

    Adipocytes store fat and provide insulation and energy reserves.

  • What are macrophages in connective tissue?

    Macrophages are immune cells that engulf pathogens and debris.

  • What distinguishes skeletal muscle cells?

    Skeletal muscle cells are long, multinucleated, and voluntary for body movement.

  • What are cardiac muscle cells?

    Cardiac muscle cells are branched, involuntary cells with intercalated discs for heart contraction.

  • Describe smooth muscle cells.

    Smooth muscle cells are spindle-shaped, involuntary cells found in walls of hollow organs.

  • What is the function of neurons?

    Neurons transmit electrical impulses to communicate information throughout the body.

  • What are glial cells?

    Glial cells support and protect neurons in nervous tissue.
