Joints Flashcards
Synarthrosis
joint that permits little or no movement
amphiarthrosis
allows slight movement
diarthrosis
freely moving joints
synostosis
fusion of adjacent bones; can be normal or pathologic
ligament
fibrous band that a connect bone to bone
tendon
fibrous band that connect muscle to bone
Fibrous joints
fibrous joints are fixed, or semi-fixed joints
generally consist of bone connected by fibrous bands/connective tissue
3 types of fibrous joints
suture (synarthrotic)
syndesmosis (amphiarthrotic)
gomphosis (synarthrotic)
Suture
synarthrotic
only found in skull
synostosis = fused suture; frontal suture
syndesmosis
amphiarthrotic
fibrous connection between 2 parallel bones
tibia/fibula; ulna/radius
Gomphosis
synarthrotic
also called post in socket joint
attach teeth to mandibular socket
2 types of cartilaginous joints
synchondosis (hyaline)
symphysis (fibrocartilage)
synchrondrosis
hyaline cartilage
epiphyseal plate –> synostosis
costo-sternal joint
symphysis
fibrocartilage
pubic symphysis
intervertebral discs
synovial joints
more complex than other joints
have joint cavity/capsule and are diarthrotic
types of synovial joints
gliding
hinge
pivot
condyloid (ellipsoid)
saddle
ball and socket
Gliding joint
intertarsal and intercarpal joints
costovertebral joints
sternoclavicular
acromioclavicular (AC) joints
sacroiliac joints
hinge joints
knee
elbow
ankle
interphalangeal joints
pivot joints
ulna-radial head (pronation/supination)
atlas/axis
condyloid joint
metacarpophalangeal joints
radiocarpal joints
metatarsophalangeal joints
saddle joint
metacarpophalangeal joint (thumb)
ball and socket joint
shoulder
hip
