Q

what fiber type forms the network of bone marrow?

A

reticular

29
Q

synarthrosis

A

immovable

30
Q

arthr

A

joint

31
Q

amphiarthrosis

A

slightly movable

32
Q

diarthrosis

A

freely movable

33
Q

nonaxial

A

a bone moves in no axis

ex: patellarfemoral joint

34
Q

uniaxial

A

a bone moves in one axis

ex: elbow joint

35
Q

biaxial

A

a bone moves in two axis

ex: hand and fingers

36
Q

multiaxial

A

a bone moves in three axis

ex: shoulder joint

37
Q

true or false: all synovial joints are diarthroses

A

true

38
Q

how is friction reduced In diarthrotic joints?

A
  1. articular surfaces are composed of articular cartilage so when cartilage rubs against cartilage friction is reduced because cartilage is smoother than bone
  2. synovial fluid reduces friction
39
Q

bursa

A

flat fluid filled sac composed of dense irrecgular connective tissue that is lined by synovial membrane

40
Q

a diarthrotic joint is classified into one of four subclasses by determining…

aponeurosis

A

sheet like structure

48
Q

origin

A

less movable body part

49
