Ch. 9 - Joints Flashcards
4 major classifications of joints
Fibrous
Cartilaginous
Bony
Synovial
Fibrous joints are AKA
Synarthroses
Cartilaginous joints are AKA
Amphiarthroses
This joint is “2 bones united by fibrous tissue”
Fibrous joint
Are fibrous joints flexible?
NO
Fibrous joints are divided into these 3 subtypes:
Suture
Syndesmosis
Gomphosis
This is an immobile fibrous joint only found on the skull
suture
There are 3 types of sutures
Serrated
Lap/Squamous
Plane/butt
Attachment of a tooth to its socket is an example of a
Gomphosis joint
A tooth is held firmly in place by a
Periodontal ligament
This joint is “bones linked by cartilage”
Cartilaginous joint
2 types of cartilaginous joints
Synchondrosis
Symphysis
A synchondrosis joint is composed of this type of cartilage
hyaline cartilage
Which of the ribs is the only synchondrosis joint? What kinds of joints are all the other ribs?
Only the first rib is a synchondrosis. Every other rib has a synovial joint
A symphysis joint is composed of this type of cartilage
Fibrous cartilage
A bony joint is AKA
Synostosis
The epiphyses of 2 conjoining bones in a synovial joint are capped with this type of cartilage
Articular cartilage
This part of a synovial joint contains synovial fluid
joint cavity
This part of the synovial joint encloses the cavity and retains the fluid
Joint capsule
Which joint is most likley to develop complications?
Synovial joints
A crescent-shaped fibrocartilage disc in the knee
Meniscus
this accessory structure attaches muscle to bone
tendons
this accessory structure attaches bone to bone
Ligaments
AKA a fibrous sac filled with synovial fluid
Bursae
inflammation of a bursa
bursitis
a form of bursitis where the tendon sheath is inflamed
tendonitis
A joint that can rotate in any plane.
(ex. hip and shoulder joint)
Multiaxial joint
A joint that moves in only 2 planes
Biaxial joint
A joint that only moves in 1 plane
Monaxial joint
Inflammation of a joint
Arthritis
More severe kind of arthritis that is an autoimmune disease and ossifies degenerated cartilage
Rheumatoid arthritis (RA)
Most common form of arthritis
Osteoarthritis (OA)
“crunching” and cracking sounds of the knee joints
Crepitus
Bones can become solidly fused, can be a result of RA
Ankylosis
Replacement of a diseased joint with an artificial device
Arthroplasty
This joint prosthesis is infiltrated with a patient’s bone to create a firmer bond
Porous-coated prosthesis
