Joints Flashcards
What are the three types of joints?
Fixed (immovable), slightly moveable (cartilaginous), freel moveable (synovial)
What amount of movement do Fixed Joints allow?
None! The clue is in the name: Immovable joints are fixed joints.
What is an example of a Fixed Joint?
Joints of the skull or sacrum
What is the function of a Fixed joint?
Protection
How much movement does a Cartilaginous Joint allow?
Only slight movement. The clue is in the name: cartilaginous joints are slightly moveable joints.
What are some examples of Cartilaginous Joints?
The joints between your vertebrae in your spine.
What amount of movement do Synovial Joints allow?
Lots. They are also known as Freely Moveable Joints and have the greatest range of movement.
What’s an example of a synovial joint?
Knee Joint
Which type of joint is used in most sporting actions?
Synovial Joints
What are the 7 main elements of a synovial joint?
(1) Ligament,
(2) Synovial Fluid,
(3) Bone Ends (which are covered with Articular or Hyaline Cartilage),
(4) Bursa,
(5) Joint Synovial Capsule (which includes the Synovial Membrane and Fibrous Capsule),
(6) Tendon,
(7) Bone Ends
Which type of joint allows the most movement?
Synovial
What are the 6 types of Freely Moveable (Synovial) Joints?
(1) Pivot,
(2) Ball and Socket,
(3) Hinge,

Synovial Joint: Ball and Socket
What is the purpose of synovial fluid?
To fill the joint capsule and lubricate and nourish the joint.
Which element of the synovial joint structure is a fluid filled sac between the tendon and the bone that helps to reduce friction?
Bursa
Which element of the synovial joint structure encases the joint, consists of the synovial membrane and fibrous capule and helps to protect the joint?
Joint Synovial Capsule
Which element of the synovial joint structure are white, fibrous cords of tissue that attach muscle to bone, are very strong (made of collagen) and are found towards the end of muscle tissue?
Tendon
Which element of the synovial joint structure is tough, connective tissue that joins bone to bone and holds the bones together?
Ligament
Which element of the synovial joint structure is made up of tough, tightly packed elastic fibres that can withstand sudden stresses and provide strength to prevent injuries such as dislocations?
Ligament
Which element of the synovial joint structure acts as a lining for the joint capsule and produces synovial fluid? (This element is one of the two, main parts of the Joint Synovial Capsule.)
Synovial Membrane
What are the two, main parts of the Joint Synovial Capsule?
Synovial Membrane and the Fibrous Capsule
What are covered with slippery hyaline (or articular) cartilage to allow the bone to move smoothly with little friction?
Bone Ends
Which elements of the synovial joint structure helps to reduce friction and why?
Bursa, because it is a fluid-filled sac
