    Hinge Joint

    • Hinge joints allow for flexion and extension movement
    • Hinge joints are found in the elbow, knee, and phalanges
    • Hinge joints allow one bone to wrap around the rounded edge of another bone

    Pivot Joint

    • Pivot joints allow only rotation
    • Pivot joints are found in the radioulnar joint and between C1 and C2, and the atlanto-axial joint
    • The radioulnar joint allows for the radius to move along the ulna to make the pronation movement
      • The dens is held in place by a ligament between C1 and C2 which allows rotational movement of C1 around the dens of C2

    Condyloid Joint

    Double-Jointed

    • Double-jointed people do not have extra joints
    • Double-jointed people have more flexible articular capsules and ligaments, which increases range of motion and decreases joint stability
    • Decreased joint stability can lead to increased injury risk and long-term problems, such as wear and tear

    Common Joint Injuries

    • Common joint injuries include cartilage tears and sprains

    Cartilage Tear

    • Cartilage tears are common overuse injuries, especially in the knee menisci
    • Fragments of cartilage can interfere with joint function
    • Cartilage tears can be treated with arthroscopic surgery
    • Cartilage is avascular and cannot repair itself due to lack of blood supply

    Sprain

    • Sprains occur when a ligament is stretched or torn
    • Healing is slow due to poor vascularization in ligaments
    • Sprains are classified on a scale of 1-3 based on the severity of the tear
      • Grade 1: slight tearing
      • Grade 2: stretching
      • Grade 3: complete tear
    • Grade 1 and 2 sprains can be treated with physiotherapy, while grade 3 sprains may require surgical reattachment or a ligament graft

    Inflammatory and Degenerative Joint Conditions

    • Inflammatory and degenerative joint conditions include tendonitis and arthritis

    Tendonitis

    • Tendonitis is caused by overuse or excessive rubbing from repetitive motion on a tendon

    • Tendons connect muscle to bone and heal slowly
    • A partial or full tear of a tendon is called a strain

    Arthritis

    • Arthritis is any condition that causes inflammation or pain in a joint
    • There are over 100 types of arthritis
    • Arthritis affects joint comfort and function
    • Causes of arthritis vary, including genetics, aging, and biomechanics
      • Biomechanics refer to how someone walks, for example, walking with toes pointing inwards can affect the alignment of the knees and hips, leading to wear and tear on the cartilage in the synovial capsule and inflammation over time

    Epithelial Tissue

    • Two types: covering/lining and glandular
    • Both form boundaries between different environments, including lining between inside/outside and glandular boundary between tunnel/inner part and rest of the body
    • Key Functions: physical protection (e.g. skin, bladder), absorption (e.g. small intestine, kidney), sensation (e.g. rods/cones, taste buds, respiratory), secretion (e.g. exocrine/endocrine glands)
      • Secretion is the key function.

    Glandular Tissues

    • Glands secrete products via endocrine and exocrine means
      • Endocrine glands secrete products directly into the bloodstream for distribution throughout the body.
        • Examples include thyroid and pituitary hormones, and insulin secretion by the pancreas.
        • These glands have single layers of epithelial cells.
      • Exocrine glands secrete products into ducts for delivery to specific locations in the body.
        • Examples include salivary which only reach specific areas of the mouth, and sweat glands, which have specific ducts to deliver to the skin. Exocrine glands have multiple layers of epithelial cells.

    Epithelial Tissue Structure

    • Apical surface faces the external environment.
    • Basal surface rests on the basement membrane.
    • Basal lamina is a layer of protein that connects the basal surface to the underlying connective tissue, forming the basement membrane.

    Epithelial Tissue Classification

    • Classified based on the number of layers and shape of the cells:
      • Number of layers
        • Simple (single layer)
        • Stratified (multiple layers)

        • Transitional (changes shape and layers)
      • Cell shape
        • Squamous (flat)
        • Cuboidal (cube-shaped)
        • Columnar (column-shaped)

    Connective Tissue

    • The main role of connective tissue is support.
    • All connective tissues develop from mesenchyme.
    • There are four main types:
      • Connective tissue proper
      • Cartilage
      • Bone
      • Blood
    • Six key functions: supporting, binding, storing reserve fuel, transporting substances, protecting, and immune protection.

    Connective Tissue Structural Elements

    • Three main structural elements:
      • Cells: macrophages, fibroblasts, mast cells, plasma cells, neutrophils, eosinophils, and adipocytes
      • Ground substance: nonliving gelatinous tissue
      • Fibers: nonliving; elastic, reticular, and collagen
    • Ground substance and fibers together form the extracellular matrix, which is the nonliving component of connective tissue.

    Connective Tissue Cells

    • Defense cells: macrophages, mast cells, plasma cells, eosinophils, and neutrophils provide a second line of defense against invaders after epithelial tissues.
    • Fibroblasts: produce fibers and ground substance.
    • Adipose cells (aka adipocytes): store lipids, provide energy storage, cushioning and protection, and secrete some hormones.

    Connective Tissue Fibers

    • Elastic fibers: yellow, composed of elastin protein, allow for stretch and recoil.
    • Reticular fibers: white, tough but flexible, form a branching network, composed of collagen protein.
    • Collagen fibers: white, strong and flexible, resistant to stretch, composed of collagen protein.

    Connective Tissue Proper

      • Irregular: contains collagen fibers in an irregular mesh pattern, providing multi-directional strength, found in skin and lining around bones and cartilage.
      • Elastic: contains collagen and elastic fibers, allowing for stretch and recoil, found in arteries and ligaments.

    Cartilage

    • Chondrocytes (cartilage cells) develop from chondroblasts and produce collagen, elastic fibers, and ground substance (similar to fibroblasts).
    • Chondroitin sulfate in cartilage ground substance provides resiliency and allows for the absorption of force.
    • Perichondrium is a dense layer of connective tissue that covers cartilage.

    Types of Cartilage

    • Hyaline cartilage: most common type, found in joints, nose, trachea.
    • Elastic cartilage: more flexible than hyaline, found in ears and epiglottis.
    • Fibrocartilage: strongest type, found in intervertebral discs and menisci.

    Joint Classification

    • Joints, also called articulations, are where two or more bones meet.
    • Joints can be classified as fibrous, cartilaginous, or synovial.
    • Fibrous joints are joined by collagen fibers of connective tissue and are either immobile or slightly moveable.
    • Cartilaginous joints are joined by cartilage and are either immobile or slightly moveable.
    • Synovial joints are covered with articular cartilage, have a joint cavity, and are enclosed within a capsule. They are freely movable.

    Common Joint Injuries

    • Cartilage tear: A common overuse injury, especially in the knee's menisci. Cartilage fragments can interfere with joint function and are typically removed via arthroscopic surgery.
