A&P - Chapter 14 (Part 3) Flashcards
What are 6 types of synovial joints?
- Hinge
- Pivot
- Saddle
- Condyloid
- Ball and socket
- Gliding
Uniaxial joints
Permit movement around 1 axis and only in 1 plane
What are 2 examples of uniaxial joints?
- Hinge
2. Pivot
Biaxial joints
Permit movement around 2 perpendicular axes and 3 perpendicular planes
What are 2 examples of biaxial joints?
- Saddle
2. Condyloid
Multiaxial joints
Permits movement around 3 or more axes and 3 or more planes
What are 2 examples of multiaxial joints?
- Ball and socket
2. Gliding
What kind of movement does ball and socket allow?
Allows the widest range of motion
What are 2 examples of ball and socket joints?
- Shoulder
2. Hip
What kind of movement does hinge allow?
Allows flexion and extension
What are 3 examples of hinge joints?
- Elbows
- Knees
- Fingers
What kind of movement does pivot joints allow?
Allows rotation
What is an example of a pivot joint?
Cervical vertebrae
What kind of movement does saddle joint allow?
Wide range of motion
What is an example of a saddle joint?
Opposing thumbs
What kind of movement does gliding joint allow?
Allows gliding motion only
What is an example of the gliding joint?
Between vertebra
What kind of movement does condyloid joints allow?
Allows flexion, extension, adduction and abduction
What is an example of condyloid joints? (2)
- Wrists
2. Fingers
What does types of movement depend on? (2)
- Shapes of the surfaces of articulating bones
2. Position of ligaments, tendons and muscles around the joints
What movements do synovial joints allow? (4)
- Angular
- Circulation
- Gliding
- Special
What movements does angular allow? (4)
- Flexion
- Extension
- Abduction
- Adduction
What movements does circular allow? (4)
- Rotation
- Circumduction
- Supination
- Pronation
What movements does gliding allow?
Gliding with no angular or circular movement
What movements does special allow? (2)
- Inversion
2. Eversion
Why is range of motion assessed?
In order to determine the extent of a joint injury using a goniometer
Gonio
Corner
Goniometer
An instrument for the precise measurement of angles
