Chapter 9: Articulations Flashcards
no movement
synarthrosis
little movement
amphiarthrosis
free movement
diarthrosis
which joints have no joint cavity (space between the articulating bone)
fibrous joints
three types of fibrous joints
suture, gomphosis, syndesmoses
immobile joint between a tooth & the jaw
gomphosis
immobile joint between bones of the skull
suture
permits slight mobility between the radius & ulna
syndesmoses
two types of cartilaginous joints
synchondrosis & symphysis
immobile joints that occur in an epiphyseal plate in a long bone & in the joint between a rib & the sternum
synchondroses
uniaxial synovial joints (3)
plane, hinge, pivot
amphiarthroses & occur in the intervertebral discs & the pubic symphysis
symphyses
biaxial synovial joints (2)
condylar, saddle
multiaxial synovial joint
ball and socket
sliding or gliding/ back & forth, side to side
linear motion
angle of bones change with respect to each other
angular motion
one bone can rotate against or within each other
rotation
pulpous extruded from inside cartilage pad (“slipped” or “ruptured” disc)
herniated disc
____ connect scapula to clavicle
ligaments
joint _____ is between humerus & scapula
capsule
_____ surrounds glenoid cavity
labrum
SITS muscles
supraspinatus, infraspinatus, teres minor, subscapularis
where do dislocations in the shoulder occur?
acrimioclavicular & glenohumeral
common injury of the knee
lateral impact
overstretching or tearing of ligament(s) around a joint
sprain
inflammation of a joint
arthritis
inflammation of a joint resulting from breakdown of articular cartilage (“wear and tear” arthritis)
osteoarthritis
inflammation of joint due to attack of synovial components by immune system
rheumatoid arthritis
