joint classification Flashcards
interphalangeal joint (manus & pes)
synovial, uniaxial, hinge
flex/extend digits I-V of pes & manus
metatarsophalangeal joints
synovial, biaxial ellipsoid
flex/extend & adduct/aBduct digits I-V of pes
intertarsal & tarsometatarsal joints (collectively called subtalar joints)
synovial, multiaxial, gliding
invert &evert pes
tibiotalar joint (aka ankle)
synovial, uniaxial, hinge
plantarflexes & dorsiflexes ankle
inferior tibiofibular joint
fibrous (ligamnets hold distal fibula to the distal lateral tibia)
(some movement for absorbing fibular stress)
superior tibiofibular joint
synovial, multiaxial, gliding
some movement for absorbing fibular stress
genicular joint
synovial, uniaxial, hinge
flexes/ extends knee, knee also glides, as well as rotates to lock/unlock
sacroiliac joint across the auricular facets
synovial, multiaxial, gliding
(slight mobility with coxae tilting relative to sacrum, absorbs shock, locks for stability, greater mobility during labor to help open pelvic outlet
sacroiliac joint across the ligaments
fibrous joint
(slight mobility, mainly functions to help stabilize pelvis, more mobile in labor– spreads apart to help open pelvic outlet)
vertebral interbody joints
cartilaginous
highly flexible, assist in flexing/extending, rotating and laterally flexing vertebral column
vertebral superior and inferior facets of adjoining vertebrae
synovial, multiaxial, gliding
assist in flexing/extending, rotating, and laterally flexing vertebral column
joint of axial (C2) dens and atlas (C1) anterior arch
synovial, uniaxial, pivot
rotated head
atlanto-occipital joint
synovial, uniaxial, hinge
flexes/ extends head
cranial sutures
fibrous
movement during one’s birth to fit the cephalon through the vagina, then the become immobile
coxal joint
synovial, triaxial, ball and socket
flexes/ extends, adducts, aBducts, and internally/ externally rotates hip
sternocostal joints
cartilaginous
some movement: assist in compression/expansion of ribcage
sternoclavicular joint
synovial, multiaxial, gliding
clavicle protracts/ retracts, elevates/ depresses, and rotates a little
acromioclavicular joint
synovial, multiaxial, gliding
some gliding movement between scapula and clavicle
epiphyseal joints of long bones
disappear by young adulthood
cartilaginous
immobile
pubic symphysis
cartilaginous
slight mobility when moving the lower extremities- absorbs shock
humeroradial joint
synovial, biaxial, *special pivot
flexes/ extends elbos, rotates to assist in pronating/supinating antebrachium
humeroulnar joint
synovial, uniaxial, hinge
*main elbow joint– flexes/ extends elbow
proximal and distal radioulnar joints
synovial, uniaxial, pivot
pivot to assist in pronating/ supinating antebrachium
glenohumeral joint
synovial, triaxial, ball and socket
flexes/ extends, adducts/ aBducts, and internally/ externally rotates shoulder
“scapula-ribcage joint”
*special sliding
elevates/depresses, protracts/retracts, and upwardly/downwardly rotates scapula
intercarpal joints
synovial, multiaxial, gliding
main action: assist in carpal flexion between proximal and distal rows
interosseus membraines of crural and antebrachial bones
fibrous
some movement, including pivoting in the antebrachium
radiocarpal joint
synovial, biaxial, ellipsoid
flexes/ extends and adducts/ aBducts wrist
main intercarpal joints
synovial, multiaxial, gliding
main action: assist in carpal flexion between proximal and distal rows
carpometacarpal joint I
synovial, biaxial, saddle
opposes/ unopposes pollex
carpometacarpal joints II-V
syovial, multiaxial, gliding
mainly assist in adduction/ aBduction of digits II-V
metacarpophalangeal (McP) joints II-V
synovial, biaxial, ellipsoid
flexes/extends & adducts/aBducts digits 11-V of manus
metacarpophalangeal joint I
synovial, uniaxial, hinge
flexes/extends digit I of manus
