    Study Notes

    Tissues and Membranes

    • Tissues are groups of similar cells working together, with shared structure and function.
    • Membranes are thin sheets of tissue covering surfaces, lining body cavities, and surrounding organs.
    • Four major tissue types: epithelial, connective, nervous, and muscular.
    • Histology is the study of tissues.
    • Epithelial tissue covers surfaces, lines cavities, and performs secretion, absorption, and protection.
      • Classified by cell shape (squamous, cuboidal, columnar) and layers (simple, stratified).
      • Simple squamous: thin, flat cells (e.g., walls of blood vessels).
      • Simple cuboidal: cube-shaped cells (e.g., kidney tubules).
      • Simple columnar: tall, narrow cells (e.g., digestive tract).
      • Pseudostratified columnar: appears layered but is single-layered (e.g., respiratory tract). Stratified squamous: multiple layers of cells (e.g., skin).
      • Stratified cuboidal: multiple layers of cuboidal cells (rare).
      • Stratified columnar: multiple layers of columnar cells (rare).
      • Transitional: specialized cells that change shape (e.g., urinary bladder).
    • Connective tissue is the most abundant tissue type, providing support, connection, protection, and storage.
      • Found in blood, under skin, bone, around many organs.
      • Connects, protects, stores fat, and transports.
      • Composed of cells embedded in an extracellular matrix (liquid, gel-like, or solid).
      • Contains fibers like collagen (strong), elastin (stretchy), and reticular (fine collagen).
      • Types: loose connective (areolar, adipose, reticular), dense fibrous connective (tendons, ligaments, fascia), cartilage (hyaline, elastic, fibrocartilage), and bone (osseus tissue).
    • Nervous tissue transmits electrical signals.
      • Contains neurons (transmit signals) and neuroglia (support neurons).
    • Muscle tissue contracts to cause movement.
      • Types: skeletal (attached to bones), smooth (walls of internal organs), and cardiac (heart).
    • Membranes include epithelial membranes (cutaneous, mucous, serous) and connective tissue membranes (synovial, periosteum, perichondrium, meninges, fascia)
    • Protection, absorption, filtration, and secretion are among the crucial functions of epithelial membranes.
    • Specialized functions of particular tissues, such as protection, secretion, support, and others are crucial.

    Tissue Functions

    • Protection: Skin and some types of epithelial tissue shield the body from the elements and pathogens.
    • Absorption: Epithelial tissue in the digestive tract absorbs nutrients.
    • Filtration: Epithelial tissue filters substances in structures like the kidneys.
    • Secretion: Epithelial glands secrete hormones and other substances.
    • Support: Connective tissue supports the body and connects its parts.
    • Movement: Muscle tissue enables body movements; skeletal muscle controls movements.
    • Conduction: Nervous tissue transmits information throughout the body.
