  • 1. Edited by Brenda Holmes MSN/Ed Associate Professor South Arkansas Community College
  • 2. Chapter 8 Joints of the Skeletal System Copyright © The McGraw-Hill Companies, Inc. Permission required for reproduction or display.
  • 3.
    • Are known as articulations
    • Functional junctions between bones
    • Bind parts of skeletal system together
    • Make bone growth possible
    • Permit parts of the skeleton to change shape during childbirth
    • Enable body to move in response to skeletal muscle contraction
    • Three (3) classifications of joints will be considered
  • 4.
    • (1) Fibrous joints
      • Dense connective tissues connect bones
      • Between bones in close contact
    • (2) Cartilaginous joints
      • Hyaline cartilage or fibrocartilage connect bones
    • (3) Synovial joints
      • Most complex
      • Allow free movement
    • These joints are also known as:
    • Synarthrotic joints
      • Considered immovable
    • Amphiarthrotic joints
      • Slightly movable
    • Diarthrotic joints
      • Freely movable
  • 5.
    • There are three (3) types of fibrous joints (synarthroses):
      • Syndesmosis
      • Suture
      • Gomphosis
    • Syndesmosis :
      • A sheet or bundle of fibrous tissue connecting bones
      • Lies between tibia and fibula (interosseous membrane)

  • 6.
    • Suture:
      • Between flat bones
      • See teeth-like projections
      • Thin layer of connective tissue connects bones
      • Skull
    • Gomphosis:
      • Cone-shaped bony process in a socket
      • Tooth in jawbone

    • There are two (2) types of cartilaginous joints (amphiarthroses):
      • Synchondrosis
      • Symphysis
    • Synchondrosis:
      • Bands of hyaline cartilage unite bones
      • Epiphyseal plate (temporary)
      • Between manubrium and the first rib (costal cartilages)

  • 27. Replacing Joints
  • 28. Joint Disorders
  • 29.
    • Joint stiffness is an early sign of aging
    • Fibrous joints first to change; can strengthen however over a lifetime
    • Changes in symphysis joints of vertebral column diminish flexibility and decrease height (remember water loss from the IVDs)
    • Synovial joints lose elasticity
    • Disuse hampers the blood supply
    • Activity and exercise can keep joints functional longer
  • 30. Important Points in Chapter 8: Outcomes to be Assessed
    • 8.1: Introduction
    • List the functions of joints.
    • 8.2: Classification of Joints
    • Explain how joints can be classified according the type of tissue that binds the bones together.

    • 8.5: Types of Joint Movements
    • Explain how skeletal muscles produce movements at joints, and identify several types of joint movements.
  • 31. Important Points in Chapter 8: Outcomes to be Assessed
    • 8.6: Examples of Synovial Joints
