Study Notes

Tissues

  • Tissues are categorized into four types based on structure and function
  • The four types are epithelial, connective, muscular, and nervous tissues
  • Epithelial tissues primarily cover surfaces
  • Connective tissue provides support and shape to the body
  • Muscular tissue is comprised of elongated cells called muscle fibers or myocytes
  • Nervous tissue is made up of neurons, also known as nerve cells

Epithelial Tissues

  • Major functions include acting as selective barriers and producing secretions on their free surfaces
  • Types include simple squamous, simple cuboidal, and stratified squamous

Simple Squamous Epithelium

  • Composed of a single layer of flat cells
  • Found in mesothelium, which lines body cavities
    • Examples include the peritoneum (abdominal organs), pleura (lungs), and pericardium (heart)

Simple Cuboidal Epithelium

  • Composed of a single layer of cube-shaped cells
  • Lines kidney tubules

Stratified Squamous Epithelium

  • Composed of several layers of cells
  • Found in locations such as skin, mouth, and esophagus

Connective Tissue (CT)

  • Functions include giving, maintaining, and supporting the shape of the body and its structures
  • Has three components: cells, fibers, and ground substance
  • Examples of cells include fibroblasts, macrophages, adipocytes

Connective Tissue Fibers

  • Collagen fibers are the most abundant protein in the human body, strong, and flexible
  • Collagen fibers are organized in parallel bundles

Muscular Tissue

  • Composed of elongated cells known as muscle fibers or myocytes
  • Types include skeletal, cardiac, and smooth

Skeletal Muscle

  • Each skeletal muscle is an organ composed of hundreds to thousands of muscle fibers
  • Muscle fibers are specialized cells specifically for skeletal muscles

Nervous Tissue

  • Composed of neurons, also known as nerve cells
  • Found in the brain, spinal cord, and nerves
