    Study Notes

    Overview of Human Tissues

    • Human body is composed of diverse tissue types, each with specific functions.
    • Tissues are categorized into four main types: Epithelial, Connective, Muscular, and Neuronal.

    Epithelial Tissue

    • Covers body surfaces and lines internal cavities.
    • Forms glands and functions in protection, absorption, secretion, and sensation.
    • Composed of tightly packed cells with minimal extracellular matrix.

    Connective Tissue

    • Supports, binds, and connects different tissues and organs.
    • Provides structural integrity, protection, and transport of nutrients and waste.
    • Composed of varied cell types and abundant extracellular matrix.
    • Divided into Embryonic and Mature Connective Tissue.

    Types of Connective Tissue

    • Embryonic Connective Tissue includes:

      • Mesenchyme: Undifferentiated cells serving as precursors to other connective tissues.
      • Mucoid: Soft tissue rich in hyaluronic acid, primarily found in umbilical cord.

    • Mature Connective Tissue consists of:

      • Loose: Areolar (supports organs), Adipose (energy reserve), Reticular (framework for organs).
      • Dense: Regular (tendons/ligaments), Irregular (dermis of skin), Elastic (walls of blood vessels).

    Muscular Tissue

    • Composed of specialized cells responsible for movement.
    • Divided into three types:
      • Skeletal Muscle: Striated, voluntary control, multi-nucleated; moves limbs.
      • Cardiac Muscle: Striated, involuntary, mono-nucleated; found in heart.
      • Smooth Muscle: Non-striated, involuntary, mono-nucleated; found in walls of organs.

    Neuronal Tissue

    • Composed of specialized cells for processing and transmitting electrical signals.
    • Essential for communication between different parts of the body.
    • Includes both central and peripheral nervous systems.

    Functions of Tissue in Organ Systems

    • Tissues work together to form organs, each with specific functions critical to maintaining bodily functions.
    • The integration of different tissue types ensures efficient performance of organ systems.
