unit 2 test day 2 Flashcards
(27 cards)
contusion
bruises= damaged blood vessel
MOI: compression type injury
SS: discoloration/tender/swelling (hematoma)
strains
torn tissue: muscle/tendon/both
MOI: tension
SS: 1st, 2nd, 3rd degree tear
1st degree tear
minimal tearing
2nd degree tear
50% tear
3rd degree tear
complete tearing
2 causes of muscle spasms
biochemical and mechanical/compression
biochemical muscle spasms
dehydration and electrolyte imbalance
tendonitis
inflammation of tendons
causes: repetitive movement
SS: inflammation, pain with contraction or stretching
joints
bone to bone
cartilaginous joint
don’t move much
in-between bone of the spine
fibrous joint
doesn’t move at all
skull bones
synovial joint
movement
articular cartilage
ends of the bone
avascular
non-living
articular capsule
covering around the joint
inside layer: produce synovial fluid
synovial fluid
helps with shock absorption
brings nutrients to articular cartilage
acts as a lubricant
ligaments
connect bone to bone: mainly collagen, unidirectional;
MOI of ligaments
shear force injuries: 1st, 2nd, 3rd degree
“sprain”
1st degree ligament tear
minimal tearing
2nd degree ligament tear
50% torn
3rd degree ligament tear
complete tearing
dislocations
bones of the joint are out of place or position
MOI of dislocation
tension type injury
SS of dislocation
deformity
decreased range of motion
bursitis
inflammation of the bursa
