ALL 6 movable joints fall under the classification of Functional/Action - but what is the name of this type of freely movable joint?
Diarthrodial - a/k/a Synovial
Explain what a Diarthrodial joint is -
Diathrodial joints are synovial joints, freely moving with a joint cavity between the articulation
There are 6 types of Diarthrodial joints - name them
1) Ball & socket
What does a ball and socket joint look like, and how does it move?
It has a ball-shaped head that articulates with a dish-shaped depresson allowing movement in every plane.
What does an Ellipsoid/Condyloid joint look like, and how does it move?
Oval shaped end of one bone articulates with an elliptical basin.
It is a biaxial joint which allow movement in 2 directions.
1) flexion/extension 2) adduction/abduction
What does a hinge joint look like?
A hinge joint can only flex and extend - one direction of movement. One direction of movement is called Uniaxial.
Describe what a "saddle joint" looks like.
A saddle joint is a concave (inward curved bone) and a convex (outward curved bone) articulate. It is a biaxial joint - it allows movement in 2 directions.
What does a Gliding/Plane joint look like?
Gliding/Plane joints look like 2 bones that have flat (or almost flat) surfaces so at the point where they articulate - the movement would be gliding. This is a non-axial joint and the movement is very minimal.
What movements does a Gliding/Plane joint make?
Gliding/plane joints make minimal movements. It is a non-axial joint.
