6 Classifications of Synovial Joints
Hinge Pivot Saddle Ellipsoid Ball and Socket Planar/Gliding
Which Structural Joint Classifications are Biaxial
Synovial Ellipsoid
Synovial Saddle
Which Structural Joint Classifications are Trilateral
Synovial Ball and Socket
Typical Parts of a Synovial Joint (5)
Articulating Bones Periosteum Articular Capsule Synovial Joint Cavity Articular Cartilage
Which parts are located INSIDE the joint capsule
Articular Cartilage
Synovial Fluid
Synovial Membrane
Which parts make up the joint capsule
Articular Cartilage
Articular Capsule
Synovial Fluid
Which 2 layers make up the Articular Capsule
Fibrous Capsule
Synovial Membrane
Functions of Synovial Fluid (3)
Lubrication
Shock Absorption
Distribution of Nutrients
Factors that Stabilize Joints (6)
1) Joint Capsule
2) Accessory, Extracapsular, or Intracapsular Ligaments
3) Shapes of Articulating Surfaces
4) Other bones
5) Skeletal Muscles
6) Other “Soft Parts” (fat pads, bursae, articular discs/menisci, fibrocartilage pads/rings)
What are the 4 Accessory Structures
1) Menisci/Articulating Discs
2) Labrum
3) Bursae
4) Tendon Sheaths
What are Menisci/Articulating Discs
Fibrocartilage pads that absorb shock, improve fit between articulating surfaces, and distribute synovial fluid
What is a Labrum
Fibrocartilaginous Lip that extends from edge of joint to deepen socket and increase area of contact
What are Bursae
Sac-like structures filled with fluid that reduce friction
What are Tendon Sheaths
Tube-like bursae that wrap around certain tendons
