Joints Flashcards
Which joint Confers the greatest Mobility in all planes?
Useful for activities, such as changing direction while walking and running.
Or reaching in various directions (shoulder)
A ball and socket joint
Which type of joint provides greater stability and is useful for propelling the body forward?
(Or drawing an object toward the body)
Hinge joint
What joint allow for limited mobility between individual vertebrae but great stability to protect the spinal cord?
Intervertebral joints
Mobility of the spinal column comes from…
Combining the limited movement of individual intervertebral joints as a whole
The joint capsule
Is connective tissue sheathing that surrounds and seals synovial joints.
The joint capsule is susceptible to…
Stretch injury when executing extreme movements in yoga postures
What lines the inside of the joint capsule?
Synovial tissue
What does the synovial tissue provide to the joint capsule?
Synovial fluid
What is synovial fluid?
A viscous lubricant for the joint surface that decreases friction during movement
How does synovial fluid work?
Circulates throughout the joint, transporting nutrients to the articulate cartilage and removing debris from the joint space
Yoga postures aid
Flexion and expansion of the joint capsule, stimulating circulation of synovial fluid
What covers the joint surfaces?
Articular cartilage
What does articular cartilage allow?
Allows smooth gliding of one bone over the other
What us one of the smoothest surfaces known to man kind
Articular cartilage
What can injure articular cartilage?
Applying excessive pressure to (this fragile) articular cartilage
