  • Joints serve 2 Essential Functions which are...

    Mobility & Stability

  • The greater range of motion...

    The Less stable the joint is

  • Use the following list and rearrange from highest mobile to High stabilized:

    • Shoulder Joint

    • Sutures of the skull

    • intervertebral Joint

    • Knee Joint

    • Shoulder Joint

    • Knee Joint

    • Intervertebral Joint

    • Sutures of the Skull

  • Which functional joint class represents still or stationary movement?

    Synarthrosis

  • Which functional joint is a slightly moveable joint with a little or average movement.

    Amphiarthrosis

  • Which functional joint class is dynamic & freely moveable?

    Diarthrosis

  • There are 3 structural joint classes such as...

    (FCS)

    Fibrous Joints, Cartilaginous Joints, Synovial Joints

  • Fibrous Joints are bound by____

    Are they structurally stable? Do they have lots of movement?

    Collagen,

    are structurally stable, have limited movement.

  • There are 3 types of fibrous joints which are....

    (SGS)

    Sutures, Gomphoses, Syndesmoses

  • Regarding sutures, what are there stability and movement? What category are they under?

    Provides structural stability

    Has no movement

    synarthrosis

  • This fibrous joint is known for "bolting" ____ in the bony sockets of our gums. What category are they under?

    Gomphoses "bolts" the teeth

    Synarthrosis

  • What ligament "glues" the teeth firmly to their bony socket?

    Periodontal Ligament

  • This fibrous joint connects bones via "ligaments" made of dense irregular connective tissue. Which category does it fall under?

    Syndesmoses "ligaments"

    Amphiarthrosis

  • What's the name of the Broad sheets of dense connective tissue between certain bones?

    Interosseous Membranes

  • The shorter the interosseous Fibers = ____ movement

    The longer the interosseous Fibers= ____ movement

    Short = Less

    Longer - More

  • Cartilaginous Joints are bound by ___

    They are structurally ___ but have ____ movement.

    Cartillage

    Stable, NO

  • What are the 2 types of cartilaginous Joints?

    (SS)

    Synchondroses, Symphyses

  • Synchondroses are bones bound by ____

    Are they stable? do they provide movement?

    Hyaline cartilage

    They are stable, they have NO movement

    can "fuse" and become synostosis

  • Which cartilaginous joints in the body's midline where bonds are bound by Fibrocartilage?

    Symphyses etc. spine pubis

    which allow a little movement (Amphiarthrosis)

  • Which joint has a dynamic/ free movement?

    Synovial Joints (Diarthrosis)

  • What is the name of the space between bones that store synovial fluid (Shock absorber)?

    Synovial Cavity

  • What is the name of the hyaline cartilage covering ends of synovial joint bones?

    Articular Cartilage

  • The Articular Capsule surrounds 2 layers which are...

    Inner Layer (synovial Membrane) - lines synovial cavity & produces synovial fluid

    Outer Fibrous Layer - dense Irregular tissue

  • What is the name of the process where synovial fluid in articular cartilages is forced out upon compression.

    Weeping Lubrication

    Moves like a water into a sponge

  • What are the Synovial fluid-filed Sacs that reduce friction between ligaments and other tissues called?

    Bursae

  • Among Bursae what is the sheath that wraps around & protects a tendon, reducing friction.

    Tendon Sheath

  • Present in the knee & hip joints which provide cushion between fibrous layer & synovial membrane are pads called...

    Fatty pads

  • What are the discs of fibro cartilage that divide the synovial cavity in two?

    Articular Discs (Menisci)
