    Study Notes

    Epithelial Tissue Types

    • Simple Squamous Epithelium: Scale-like cells found in the lungs and blood vessels, facilitating diffusion and filtration.
    • Simple Cuboidal Epithelium: Box-like cells primarily located in kidney tubules, involved in secretion and absorption.
    • Simple Columnar Epithelium: Column-like cells line digestive organs such as the intestines and basal areas, specializing in absorption and secretion.
    • Pseudostratified Columnar Epithelium: Appears multi-layered but is a single layer with cilia and goblet cells; found in the respiratory tract (trachea) helping in movement of mucus.
    • Stratified Squamous Epithelium: Multi-layered tissue for protection, prevalent in the skin.
    • Stratified Cuboidal Epithelium: Protective tissue mainly associated with sweat, mammary, and salivary glands.
    • Stratified Columnar Epithelium: Protects and secretes; found in parts of the male urethra.
    • Transitional Epithelium: Specialized for stretching, lining the urinary bladder.

    Glandular Epithelium

    • Endocrine Glands: Ductless glands that secrete hormones directly into the bloodstream (e.g., thyroid, pituitary).
    • Exocrine Glands: Glands with ducts that secrete substances such as sweat, milk, or saliva to external surfaces.

    Connective Tissue Types

    • Loose Connective Tissue: Provides support and flexibility; includes areolar (mesh-like structure), adipose (fat storage and insulation), and reticular (web-like for lymphatic tissues).
    • Dense Connective Tissue: More collagen fibers, providing strength; subdivided into dense regular (parallel fibers, e.g., ligaments and tendons) and dense irregular (random orientation, e.g., dermis).
    • Cartilage:
      • Hyaline Cartilage: Found in embryonic skeleton, ribs, and various joints.
      • Elastic Cartilage: Provides flexibility; found in the external ear, epiglottis.
      • Fibrocartilage: Tough cartilage for shock absorption found in knee joints and intervertebral discs.

    Bone and Blood

    • Bone: The hardest type of connective tissue, providing protection and structural support, containing osteocytes.
    • Blood: Liquid connective tissue comprising plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).

    Muscle Tissue Types

    • Skeletal Muscle: Voluntary, striated muscle responsible for locomotion and posture, requiring conscious control.
    • Cardiac Muscle: Striated and involuntary muscle found exclusively in the heart, responsible for pumping blood.

    Nervous Tissue

    • Neuroglia: Non-neuronal cells in the nervous system that support and protect neurons.
      • Astrocytes: Provide structure and regulate blood flow; maintain the blood-brain barrier.
      • Oligodendrocytes: Form myelin sheath in the central nervous system to insulate axons and facilitate faster signal transmission.
      • Schwann Cells: Produce myelin sheaths in the peripheral nervous system.
      • Microglia: Act as immune cells, responding to injury or disease by removing debris.
      • Ependymal Cells: Line the central canal of the spinal cord and produce cerebrospinal fluid (CSF), providing cushioning and support.
