Question 6

cartilaginous joints are divided into two parts which are?

Answer 6

primary and secondary

Question 7

bones are united by a bar or a plate of hyaline cartilage
no movement is possible

Question 8

bones united by a bar or a plate of fibrocartillage
a small amount of movement is possible

Question 10

examples of secondary c joints

Answer 10

sympahsis of the pubic bone and joints between the vertebral bodies

Question 11

describe synovial joints

Answer 11

the periosteum of thetwo articuating bones fuse togetehr forimng the fibrous capsule
a thin layer of hyaline cartiage lines each bone also called articular cartilage
the synovial membrane lines the cavity relaesing synovial fluid into the joint cavity between the two bones
together the fibrous cartilage and the synovial membrane make the articular capsule taht protects the joint from the outisde
