Back Arthrology Flashcards
planar joint
- example
- axes
- movement
- ex: acromioclavicular joint (scapula and clavicle)
- uniaxial
- gliding/sliding movement of two flat pieces
ginglymus joint
- example
- axes
hinge joint
- elbow joint (flexion and extension)
- uniaxial
trochoid joint
- examples
- axes
pivot joint
- ex: atlanto-axial joint (C1&C2) (rotation of head)
- ex: both radio-ulnar joint (supination and pronation)
- uniaxial
condyloid joint
- example
- axes
- ex: radiocarpal joint
- metacarpophalangeal joint
- biaxial
- flexion, extension, abduction, adduction, circumduction
~no rotation~
sellar joint
- example
- axes
- movement
saddle joint
- ex: carpometacarpal joint
- biaxial
- flexion, extension, abduction, adduction, circumduction
~very little rotation~ (false circumduction w/o rotation)
spheroidal joint
- example
- axes
- movement
hip and shoulder
- multiaxial
- flexion, extension, abduction, adduction, rotation, ~ circumduction~
serrated suture joint
interlocking bone with a jagged edge
squamous suture joint
joned bone with two sloping surfaces
planar suture joint
two blunt ends are joined by fibrous connective tissue
schindylesis
- example
tongue-in-groove joined by fibrous connective tissue
- ex: rostrum of sphenoid bone and perpendicular plate of ethmoid bone with vomer
gomphosis
- example
peg-in-socket joined by fibrous connective tissue
- ex: teeth in gums
syndesmosis
- example
two bones separated by a fibrous membrane
- ex: interosseous membrane in the forearm that joins the radius and ulna
synchondrosis
- example
type of cartilaginous joint characterized by temporary cartilaginous unions of hyaline cartilage
- ex: first rib and sternum
symphysis
- example
strong, slightly moveable joints united by fibrocartilage
- ex: pubic symphysis joint
compound joint
joint that includes articulations from more than one of the three categories of joints (synovial, fibrous, cartilaginous)
