joint classification

Question 1

interphalangeal joint (manus & pes)

Answer 1

synovial, uniaxial, hinge

flex/extend digits I-V of pes & manus

Question 2

metatarsophalangeal joints

Answer 2

synovial, biaxial ellipsoid

flex/extend & adduct/aBduct digits I-V of pes

Question 3

intertarsal & tarsometatarsal joints (collectively called subtalar joints)

Answer 3

synovial, multiaxial, gliding

invert &evert pes

Question 4

tibiotalar joint (aka ankle)

Answer 4

synovial, uniaxial, hinge

plantarflexes & dorsiflexes ankle

Question 5

inferior tibiofibular joint

Answer 5

fibrous (ligamnets hold distal fibula to the distal lateral tibia)

(some movement for absorbing fibular stress)

Question 6

superior tibiofibular joint

Answer 6

synovial, multiaxial, gliding

some movement for absorbing fibular stress

Question 7

genicular joint

Answer 7

synovial, uniaxial, hinge

flexes/ extends knee, knee also glides, as well as rotates to lock/unlock

Question 8

sacroiliac joint across the auricular facets

Answer 8

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

Question 9

sacroiliac joint across the ligaments

Answer 9

fibrous joint

(slight mobility, mainly functions to help stabilize pelvis, more mobile in labor– spreads apart to help open pelvic outlet)

Question 10

vertebral interbody joints

Answer 10

cartilaginous

highly flexible, assist in flexing/extending, rotating and laterally flexing vertebral column

Question 11

vertebral superior and inferior facets of adjoining vertebrae

Answer 11

synovial, multiaxial, gliding

assist in flexing/extending, rotating, and laterally flexing vertebral column

Question 12

joint of axial (C2) dens and atlas (C1) anterior arch

Answer 12

synovial, uniaxial, pivot

rotated head

Question 13

atlanto-occipital joint

Answer 13

synovial, uniaxial, hinge

flexes/ extends head

Question 14

cranial sutures

Answer 14

fibrous

movement during one’s birth to fit the cephalon through the vagina, then the become immobile

Question 15

coxal joint

Answer 15

synovial, triaxial, ball and socket

flexes/ extends, adducts, aBducts, and internally/ externally rotates hip

Question 16

sternocostal joints

Answer 16

cartilaginous

some movement: assist in compression/expansion of ribcage

Question 17

sternoclavicular joint

Answer 17

synovial, multiaxial, gliding

clavicle protracts/ retracts, elevates/ depresses, and rotates a little

Question 18

acromioclavicular joint

Answer 18

synovial, multiaxial, gliding

some gliding movement between scapula and clavicle

Question 19

epiphyseal joints of long bones

disappear by young adulthood

Answer 19

cartilaginous

immobile

Question 20

pubic symphysis

Answer 20

cartilaginous

slight mobility when moving the lower extremities- absorbs shock

Question 21

Question 22

humeroulnar joint

Answer 22

synovial, uniaxial, hinge

*main elbow joint– flexes/ extends elbow

Question 23

proximal and distal radioulnar joints

Answer 23

synovial, uniaxial, pivot

pivot to assist in pronating/ supinating antebrachium

Question 24

glenohumeral joint

Answer 24

synovial, triaxial, ball and socket

flexes/ extends, adducts/ aBducts, and internally/ externally rotates shoulder

Question 25

"scapula-ribcage joint"

Answer 25

*special sliding | elevates/depresses, protracts/retracts, and upwardly/downwardly rotates scapula

Question 26
