Joint Classifications

Question 1

what are the 3 types of joints

Answer 1

fibrous (fixed)
cartilaginous (slightly movable)
synovial (freely movable)

Question 2

characteristics of fibrous joints

Answer 2

• held together by only a ligament

- e.g. flat bones in cranium, teeth

Question 3

characteristics of cartilaginous joints

Answer 3

• where bones are joint together by cartilage
• slightly movable
  (vertebrae)

Question 4

characteristics of synovial joints

Answer 4

• most common joint classification in skeleton
• highly movable (mostly in appendicular skeleton)
• synovial capsule surrounds joint to enclose synovial fluid
• synovial membrane secretes synovial fluid (lubricant)
• hyaline/articulating cartilage at the end of bones

Question 5

function of bursa

Answer 5

fluid filled sac that sits between joint capsule and muscle to lift muscle away from joint capsule to prevent friction during a muscle contraction

Question 6

what are the 6 types of synovial joints

Answer 6

• ball & socket (shoulder, hip)
• hinge (elbow, knee)
• pivot (neck joints (top of vertebrae))
• condyloid (wrist)
• saddle (in the hand)
• gliding (in the hand)
