Define what a joint is
point at which 2 bones join together or articulate
Name the 3 main types of joints and give one example of each:
Fibrous (immovable) - include the sutures of some skull bones.
Cartilaginous (partially moveable) - intervertebral disc between adjacent vertebra of the spine.
Synovial (freely moveable) - The knee.
Name the 6 types of synovial joints.
hinge pivot saddle condyloid plane ball-and-socket
Hinge joint is?
uniaxial
- permit flexion/extension
- ex: eblow
Pivot joint is?
uniaxial
- permit rotation
- ex: neck, lets us say NO!
Saddle joint is?
biaxial
- permit flexion, extension, abduction, adduction and circumduction.
- ex: base of thumb
Condyloid joint is?
biaxial
- permit flexion, extension, abduction, adduction and circumduction.
- ex: finger joints
Plane joint is?
simple gliding movement
-ex: shoulder between the clavicle & scapula
Ball-and-socket joint is?
multiaxial
- permits flexion, extension, abduction, adduction, and medial/lateral rotation and circumduction.
- ex: hip
What are the structures of the synovial joint?
synovial fluid
articular cartilage
joint capsule
Function of synovial fluid?
provides nutrition, lubrication and shock absorption
Function of articular cartilage?
provides smooth surface for movement
What is the term used to describe the combination movement at the carpometacarpal joint (base of the thumb; not the knuckle joint of the thumb) when the pad of the first digit (aka: the thumb) is brought to another digit pad (fingers 2-4)? What is the opposite movement called?
opposition and reposition
Name the movements that occur at the ankle (talocrural) joint.
Dorsiflexion. Plantarflexion
Name the movements that occur at the intertarsal joint (subtalar + transverse tarsal joints).
Inversion. Eversion
Name the movements that occur at the knee joint.
Flexion and extension.
Circumduction at the shoulder joint involves what movements?
Flexion. Abduction. Extension. Adduction.
Explain the difference between closed chain and open chain movement.
Closed chain - is where your stationary or fixed to something. Example a squat, the feet press to the floor and help raise the body.
Open chain - when the feet or hands are free. Example would be a leg curl machine, when the leg is free to swing down.
Name the movements that occur at the intervertebral joints.
Flexion/extension, lateral side bending right and left, rotation right and left.
What is another term for radial deviation of the wrist? Remember anatomical position.
radial flexion
Closed chain anterior pelvic tilt of the pelvis is similar to what open chain hip movement?
Closed chain anterior pelvic tilt is similar to open chain hip flexion.
Closed chain posterior pelvic tilt of the pelvis is similar to what open chain hip movement?
Closed chain posterior pelvic tilt is similar to open chain hip extension.
