Muscle Flashcards
concern with teenage girl and backpain
UTI –> pylonephritis
bone pain characteristics
deep, aching, throbbing, worse at night
muscle pain characteristics
crampy, stiff, sore, achy
joint pain characteristics
synovial inflammation, tenderness
concern with landscaper?
Lyme disease
NSAIDS and ASA chronic use concerns
ulcers, increase BUN and creatinine
rheumatoid arthritis
autoimmune disease, symmetrical
- morning stiffness >1hr
- profound fatigue
- improves with activity
- worse with rest
- systemic
osteoarthritis
due to wear and tear
- <30min morning stiffness
- minimal fatigue
- worse with activity
- improves with rest
- not systemic
Gout
d/t increased uric acid
Ankylosing Spondylitis
HLAB27 test for genetic disorder that causes bones in the spine to fuse
concerning signs of a serious pathology
- erythema, warmth, effusion, decreased ROM
- fever, rash, chills, acute joint pain
- underlying bleeding disorder with anticoag use
- bone pain, weight loss, night pain
acute joint pain in a sexually active young adult could indicate?
syphilis or gonorrhea
articular structures
connects bones - consists of joint capsule, articular cartilage, synovium, and synovial fluid
extra articular structures
ligaments, tendons, nursae, muscle, fascia, bone, nerve, overlaying skin
Synovial Joints
freely moveable, covered by articular cartilage
- self lubricating, almost frictionless
- able to withstand compression and maintain heavy loads
- knee or shoulder
(diathrosis)
Fibrous Joints
immobile, connected by fibrous connective tissue between bones
- skull
(synarthrosis)
cartilaginous joints
connected by cartilage. less movement than synovial yet more than fibrous.
- discs allow flexion and extension, cushion/shock absorber
- protects spinal cord, brain, and nerves
(amphiarthrosis)
types of synovial joints
- spheroidal
- hinge
- condylar
spheroidal joint
ball and socket
- convex within a concave cavity
- wide range of motion
- shoulder/hip
hinge joint
flat, planar
- motion in one plane: flexion, extension
- hand, foot, elbow joints
condylar joint
convex or concave articulating surfaces
- movement of two surfaces
- knee, TMJ
Bursae
disc-shaped synovial sacs
- cushions movement of tendons and muscle over bone
- lie b/w skin and convex surface of bone/joint and where muscles or tendons run against bone
Rotator Cuff muscles
- Supraspinatus.
- This holds your humerus in place and keeps your upper arm stable. - Infraspinatus.
- This is the main muscle that lets you rotate and extend your shoulder. - Teres Minor.
- This is the smallest rotator cuff muscle. - Subscapularis.
Tendons
collagen fibers that connect muscle to bone
ligaments
rope like bundles of collagen fibrils
bone - bone
Cartilage
firm tissue that is softer and more flexible than bone
- connects bones together
muscle grading system
0 = contraction/paralysis 1 = feel contraction yet no movement 2 = passive ROM 3 = full ROM against gravity 4 = full ROM some resistance 5 = full ROM with resistance
flexion
decreasing joint angle
extension
increasing joint angle
abduction
motion away from midline
adduction
motion toward midline
rotation
pivotal
internal - towards midline
external - away from midline
Temporal Arteritis (TA)
- systemic vasculitis, “giant cell”
- Present = new headache, 50+ yrs old, with a high ESR (erythrocyte sedimentation rate)
- jaw pain –> blindness d/t compression and inflammation
bones of the shoulder
humerus
scapula
clavicle
sternum
parts of scapula
glenoid
acromion
coracoid
scapular body
