Fibrous joints
|
lack a synovial cavity
little or no movement 3 types: sutures, syndesmoses (tibia to fibula) and gomphoses (tooth to bone) |
|
|
Cartilaginous joints
|
no synovial cavity
little to no movement bones tightly connected by hyaline/fibrocartilage ie: between vertebre, pubic symphysis |
|
|
Synovial joints
|
synovial cavity separates the articulating bones.
freely movable articular cartilage articular capsule |
|
|
Bursa
|
sac-like structures between skin and bone, ligament and bone or tendon and bone that reduce friction
|
|
|
Menisci
|
layer of fibrocartilage between articular surfaces. Allow two bone of different shapes to fit together tightly
|
|
|
4 types of movement in synovial joints
|
gliding
angular rotation special |
|
|
planar joints
|
bone surfaces are flat or slightly curved
side to side movement only ie: carpals |
|
|
hinge joints
|
convex surface of one bone fits into a concave surface of another bone.
movement: flexion, extension, hyperextension ie: knee, elbow |
|
|
pivot joints
|
a round surface of one bone fits into a ring formed by another bone.
Movement: rotational ie: axis and atlas |
|
|
condyloid joint
|
an oval shaped condyle of one bone fits into an eliptical cavity of another bone.
movements: rotation, flexion, extension, abduction, adduction ie: thumb |
|
|
saddle joint
|
shaped like a saddle
|
|
|
ball and socket joint
|
the ball shaped surface of one bone fits into a cup-like depression of another
Movements: all ie:shoulder and hip bone |
