Musculoskeletal System and Rheumatoid Arthritis Flashcards
(59 cards)
Joints/Articulation
where two or more bones are attached
Synovium
What does synovium produce?
Inner lining of joint capsule
- produces synovial fluid
Synovial fluid
What does synovial fluid provide nutrient for?
slippery fluid that reduces friction b/w two oppossing bones
- pvds nutrients to joints/cartilage
Hyaline Cartilage
How does hyaline cartilage function?
glistening and white cartilage that covers the articular surface to absorb shock and allow smooth movement
- pvds lubrication aallows bones to move without sliding against each other
Synovial Joints
freely moveable joining where opposing surfaces are covered with smooth layer of hyaline cartilage and are enclosed by a tough joint capsule
Pannus
abnormal tissue growth in the joints
Malalignment
Incorrect alignment of the joints
RA Nodules
where cvan RA nodules also appear
small lumps of tissue under the skin, typically affecting fingers first
- can also appear on elbows, forearms, knees and back of the knee
Synovectomy
surgery done by open incision or via laparoscopic procedure to remove synovium from joints with chronic inflammation
Swan Neck Deformities
middle knuckle of a finger bends backward while the fingertip bends forward, resembling a swan’s neck
Ulnar Deviations
Fingers start bending/deviating towards the pinky finger
Sjogren’s Syndrome
develops in the presence of RA causing dry glands, affecting mouth, eyes, vagina
Crepitus
grating sensation or sound that may occur when moving the affected joints
Hyaluronic Acid
a natural substance that acts as a lubricant and shock absorber in joints
Arthrocentesis (Joint Aspiration)
the joint is aspirated and tested for presence of uric acid crystals
Hyperuricemia
high levels of uric acid in the blood
kyphosis
outward curvature of the thoracic spine causing a humpback
CSM
- Circulation
- Sensation
- Motion/Movement
Atelectasis
reversible collapse of the lung
How many bones are in the human body?
