Pivot Joint
100
what are the characteristics of a pivot joint?
- synovial joint in which the ends of two bones connect
100
what are the movements of a pivot joint?
- allow for rotation which can be external or internal
- permits movement of bones around a single axis
100
Where is the pivot joint found?
- directly under the head
- the forearm (radius and ulna) against the humerus
200
What type of articulation is this
Hinge Joint
200
what are the characteristics of a hinge joint?
- synovial joint
-hinge joints are formed between two or more bones where the bones can only move along one axis to flex or extend
200
what are the movements of a hinge joint?
- allow for bending and straightening movements
- Bones move in one direction back and forth with limited motion along the other planes
200
Where is the hinge joint found?
- knees
- elbow
- toes
- ankle
- fingers
300
What type of articulation?
Saddle Joint
300
what are the characteristics of a saddle joint?
- synovial joint
- do not allow axial rotation
- allow flexion/extension, abduction/adduction, and circumduction
300
what are the movements of a saddle joint?
- allow movement with two degrees of freedom (flexion-extension) & (abduction-adduction)
300
Where is the saddle joint found?
- thumb
- shoulder
400
what type of articulation?
plane joint
400
what are the characteristics of a plane joint?
- synovial joint
- Two smooth surfaces that slide over one another
400
what are the movements of a plane joint?
- allows for movement on the same articular surface
400
Where is the plane joint found?
- ankles
- wrist
- spine

What (types) of articulations are these?
Ball an Socket joint
Condyloid joint
500
what are the characteristics of a ball an socket joint?
what are the characteristics of a condyloid joint?
- synovial joint
Ball an Socket
- ball shaped head which connects to a cup shaped cavity
Condyloid
- "egg" shaped bone that fits into a cavity that is similar shaped
500
what are the movements of a ball an socket joint?
what are the movements of a condyloid joint?
ball an socket joint
- allows for movement along all planes
- allows for rotational movement along the central axis
Condyloid joint
- allow for side to side movement
- back and forth movement
- no rotational movement
500
Where is the ball an socket joint found?
Where is the condyloid joint found?
ball an socket
- hip joint
- shoulder
condyloid
- elbows
- wrist
