joints Flashcards
what are the 3 types of joint?
fibrous
cartilaginous
synovial
what are the 3 types of fibrous joint?
what are the fibres or ligaments that connect the bones at each of the joints?
sutures - sharpeys fibres
gomphoses - periodontal ligaments
syndesmoses - membranes
what level of movement is allowed at fibrous joints?
none-little
where are the suture (fibrous) joints only found?
between skull bones
give an example of a gomphoses fibrous joint
teeth (peg and socket)
give an example of a syndesmoses fibrous joint
between radius and ulna
what level of movement is allowed at cartilaginous joints?
some (more than fibrous)
from stretch of cartilage
what are the 2 types of cartilaginous joints?
primary (synchondrosis)
secondary (symphysis)
what type of cartilage makes up primary (synchondrosis) cartilaginous joints?
hyaline
what type of cartilage makes up secondary (symphysis) cartilaginous joints?
fibrocartilage
give an example of a primary (synchondrosis) cartilaginous joint
costochondral
between rib and costal cartilage
give an example of a secondary (symphysis) cartilaginous joint
between hip bones in pelvis
what level of movement is allowed at synovial joints?
freely moveable
what is the structure of a synovial joint?
- outer joint capsule = fibrous
- inner part = synovial
filled with synovial fluid
what are the 6 types of synovial joint?
hinge - one axis of movement pivot -roation saddle - limits rotation plane ball and socket - all movements condyloid
