wide range of mobility

Question 13

synovial joints bones seperated by what

Answer 13

joint cavity

Question 14

what is the joint cavity

Answer 14

a space filled with synovial fluid (where bones are separated in synovial joint)

what is synovial fluid secreted by

Answer 15

synovial membrane

Question 16

synovial fluid purpose (2)

lubricate joint
provide nutrition to hyaline cartilage

instrascapular ligaments purpose and location

Answer 21

stabilisers inside the joint

Question 22

menisci are

allows rotation e.g. atlanto - axial joint (cervical vertebrae)

Question 27

hinge joint function and examples

ligaments are

Answer 36

connecting bone to bone

Question 37

ligaments stabilise

Answer 37

joints

Question 38

2 main ligament types

Answer 38

extra-capular ligament and intra-capular ligament
