Anatomy- Joints
how are function joints classified
according to the degree of movement
pubic symphosis
amphiarthrodial ( fibrous)
slightly moveable joints
amphiarthrosis
vertebral BODY
ampiharthordial-fibrous ( slightly moveable-stability)
what structural joint has no joint cavity and is held together by cartilage
cartilagenous joint (pubic symphosis, intervertebral disk, manubrium and sternum)
hip
diarthrodial--> synovial -->ball and socket
shoulder
diarthrodial--> synovial -->ball and socket
shoulder and hip joints
diarthrodial--> synovial -->ball and socket
atlanto-occipital
diarthrodial--> synovial -->condyloid
metacarpophalangeal (knuckles)
diarthrodial--> synovial -->condyloid
ACROMION + CLAVICLE-->
diarthrodial--> synovial -->gliding
CARPALS of WRIST-->
diarthrodial--> synovial -->gliding
ELBOW-->
diarthrodial--> synovial -->hinge
INTERPHALANGEAL
diarthrodial--> synovial -->hinge
elbow, knee, and ankle?
diarthrodial--> synovial -->hinge
KNEE
diarthrodial--> synovial -->hinge`
ATLAS + AXIS-->
diarthrodial--> synovial -->pivot
PROXIMAL RADIUS + ULNA
diarthrodial--> synovial -->pivot
carpometacarpal of the thumb
diarthrodial--> synovial -->saddle
sternoclavicular joint
diarthrodial--> synovial -->saddle
thumb and metcarpals
diarthrodial--> synovial -->saddle
wrist
diarthrodial--> synovial -->saddle
interertebral disk facets
diarthrodial-->synovial-->gliding ( flexibility)
are synovial joints synarthrosis, amphiarthrosis, or diarthrosis?
diarthrosis
freely movable joints
diarthrosis
condyloid joint AKA
ellipsoid
****what are the three types of structural joints
fibrous (ie, sutures) cartilagenous (ie pubic symphosis) synovial (diarthrodial)
what structural joint has no joint cavity and is held together by fibrous connective tissue
fibrous joint ( ie- suture, gomphosis-teeth joint-)
what type of fibrous joint has a cone shaped process that fits into a socket
gomphosis ( teeth)
what are the 6 synovial joints?
plane (gliding) hinge (ginglymus) pivot (trochoid) condyloid (ellipsoid) saddle (sellar) ball and socket (spheroid)
where do you find syndesmosis joints
radius and ulna/ tibia fibula
where do you find gomphosis joints?
roots of teeth
are syndesmosis immovable, slighly movable, or freely movable?
slightly movable
what type of joint is found between flat bones of the skull
sutures
what are the three types of fibrous joints
sutures ( cranial bones) syndesmosis ( inferior tibiafibular) gomphosis ( teeth )
what cartilagenous joint is found in IVD's and between pubic bones
symphysis
what kind of cartilagenous joint is 2 bones joined by fibrocartilage
symphysis
which cartilagenous joint is slightly movable?
symphysis
which kind of catilagenous joint provides strength and shock absorption as well as flexibility
symphysis
SUTURES of cranial bones
synarthrodial (fibrous)
GOMPHOSIS
synarthrodial(fibrous)
first rib + sternum
synarthrodial(fibrous)- synchondrosis
are sutures synarthrosis, amphiarthrosis, or diarthrosis?
synarthrosis
immovable joints
synarthrosis
what are the three types of functional joints
synarthrosis ( SIN- not moving) amphiarthrosis (AMBI- both, slightly moving) diarthrosis ( freely moving DIA- around)
what cartilagenous joint is the epiphyseal plate of the long bone
synchondrosis
what kind of cartilagenous joint is between the first rib and manubrium of sternum
synchondrosis
what type of cartilagenous joint is 2 bones joined together by hyaline cartilage
synchondrosis
what are the 2 types of cartilagenous joints
synchondrosis ( first rib and sternum- hyaline cartilage connection) symphysis ( pubic)
in what kinds of fibrous joint are bones are held together by fibrous ligaments or membranes
syndesmosis ( inferioir tibia fibular)
what type of structural joint has bone ends covered with articular cartilage, united by an articular capsule and ligaments
synovial joints
what type of structural joint has a joint cavity, synovial membrane, and synovial fluid.
synovial joints (plan/gliding- vertebral facets. saddle-thumb. hinge-elbow. pivot- proximal radioulnar. ball and socket- shoulder. ellipsoid/condylar- occipitoatlas joint)
