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)
