  • Simple Columnar Epithelium: Single layer of column-shaped cells; functions in secretion and absorption. Location: lining of the stomach and intestines.
  • Pseudostratified Columnar Epithelium: Single layer of cells of varying heights; functions in secretion and propulsion of mucus. Location: lining of the trachea.
• Stratified Epithelium: Multiple layers of cells.
  • Stratified Squamous Epithelium: Multiple layers of flattened cells; protects underlying tissues in areas subjected to abrasion. Location: epidermis of the skin, lining of the mouth.
  • Stratified Cuboidal Epithelium: Typically two layers of cube-shaped cells; functions in protection and secretion. Location: ducts of some glands.
  • Stratified Columnar Epithelium: Several layers of column-shaped cells; functions in protection and secretion. Location: male urethra, large ducts of some glands.
  • Transitional Epithelium: Several layers of cells that can change shape; allows distension of urinary organs. Location: lining of the urinary bladder.

2. Connective Tissue: The Support System

Connective tissue provides support, connects, and separates different types of tissues and organs in the body. It is characterized by having an extracellular matrix composed of ground substance and fibers. Major functions include binding and support, protection, insulation, and transportation (blood). Key components include:

• Cells: Different cell types (fibroblasts, chondrocytes, osteocytes, etc.) produce the matrix.
• Extracellular Matrix: Composed of ground substance and fibers (collagen, elastic, reticular).
• Vascularity: Varies from highly vascular (bone) to avascular (cartilage).

Types of Connective Tissue:

• Connective Tissue Proper:
  • Loose Connective Tissue:
    • Areolar Connective Tissue: Wraps and cushions organs; plays an important role in inflammation. Location: widely distributed under epithelia.
    • Adipose Tissue: Provides reserve food fuel; insulates against heat loss; supports and protects organs. Location: under skin, around kidneys and eyeballs.
    • Reticular Connective Tissue: Forms a soft internal skeleton that supports other cell types. Location: lymphoid organs (lymph nodes, spleen).
  • Dense Connective Tissue:
    • Dense Regular Connective Tissue: Attaches muscles to bones or to muscles; attaches bones to bones. Location: tendons, ligaments.
    • Dense Irregular Connective Tissue: Withstands tension exerted in many directions; provides structural strength. Location: dermis of the skin, fibrous capsules of organs and joints.
    • Elastic Connective Tissue: Allows recoil of tissue following stretching; maintains pulsatile flow of blood through arteries. Location: walls of large arteries.
• Cartilage:
  • Hyaline Cartilage: Supports and reinforces; has resilient cushioning properties. Location: covers the ends of long bones in joint cavities; forms costal cartilages of the ribs.
  • Elastic Cartilage: Maintains the shape of a structure while allowing great flexibility. Location: external ear.
  • Fibrocartilage: Tensile strength allows it to absorb compressive shock. Location: intervertebral discs, knee joint.
• Bone Tissue (Osseous Tissue): Supports and protects; provides levers for the muscles to act on; stores calcium and other minerals. Location: bones.
• Blood: Transports respiratory gases, nutrients, wastes, and other substances. Location: contained within blood vessels.

3. Muscle Tissue: The Movers

Muscle tissue is responsible for movement. It is highly vascularized and innervated, and its cells are called muscle fibers. The three types of muscle tissue are:

• Skeletal Muscle: Voluntary movement; attached to bones. Cells are long, cylindrical, and striated.
• Cardiac Muscle: Involuntary movement; found in the heart. Cells are branched and striated, connected by intercalated discs.
• Smooth Muscle: Involuntary movement; found in the walls of hollow organs. Cells are spindle-shaped and non-striated.

4. Nervous Tissue: The Communicators

Nervous tissue is responsible for communication and control. It is composed of neurons (nerve cells) and neuroglia (supporting cells). Key components include:

• Neurons: Generate and conduct electrical signals.
• Neuroglia: Support, insulate, and protect neurons.

Location: brain, spinal cord, and nerves.
