fiberous
no movement
cranium
cartilaginous
small movement
sternum ribs
synovial allows movement
knee hip wrist neck
ball and socket
allows greatest range of movement one end of bone is shaped like a ball and fits into a hollow socket at the other end of the joint
hinge
HINGE JOINTS allow extensive
flexion and extension (Bending
and straightening) with only a
small amount of rotation.
* The joint is made by the joining of
two bone ends which have smooth
surfaces. They are shaped to
move against each other with
minimum friction.
Examples of Hinge Joints:
Elbow and Knee Joints
- PIVOT JOINTS
allows rotation
neck
plane
allow
flexion and extension
through a slight gliding
motion between the ends of
small bones such as hands
and feet.
These small bones can
move over one another to
increase the flexibility of the
hands and feet.
* Strong ligaments link them
together and stop them
moving to far.
saddle
SADDLE JOINTS occur
where concave and
convex surfaces meet.
* The saddle joints allow
the movement of the
joint forward and
backwards, and right to
left.
* Examples of saddle
joints include the fingers
and thumbs
condlyoid
moves in all directions metacarpals metatarsals
