Synovial Joints Flashcards
What is the role of synovial fluid?
To lubricate the joint
Reduce friction and wear and tear
What is a synovial joint?
A synovial joint is a type of joint that allows for free movement between the bones it connects.
What is the function of cartilage?
Surrounds joints
Reducse friction and acts as shock absorber

Name one function of synovial fluid.
To reduce friction between the articular cartilage of synovial joints.
what is the function of the synovial membrane
makes and releases synovial fluid to lubricate the joint
what is the role of the bursae
acts as a cushion between muscles ligaments and bones to glide and pass one another without friction

what is the function of a ligament
connects bone to bone
what do tendons do
connects muscles to bone
What is the function of the joint capsule?
Stabilises the joint
