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
