A

synovial
fibrous
cartilaginous

24
Q

what is a synovial joint?

A

extensive movement
smooth cartilage
synovial fluid in a capsule

25
Q

what is a fibrous joint?

A

no synovial cavity
joint held together by dense connective tissue

26
Q

give an example of a synovial joint?

A

elbow
knee
hip

27
Q

give an example of a fibrous joint?

A

skull

28
Q

what is a cartilaginous joint?

A

no synovial
little moment held together by cartilage

29
Q

give an example of a cartilaginous joint?

A

pelvis

30
Q

what are the components of synovial joints?

A

bones
articular (hyaline) cartilage
marginal (fibro) cartilage
synovial fluid
joint capsule
ligaments (passive stabilisers)
musculo tendinous support (active stabilisers)
tendons
muscle to move joint

31
Q

do the sutures of the skull move? why?

A

no movement to allow skull growth to adulthood

32
Q

what are syndesmoses?

A
  • fibrous joint between 2 bones, linked by ligaments and a strong membrane
  • greater distance between articular surface
  • more dense connective tissue
  • distal tibia and fibula
33
Q

when does the anterior fontanelle close?

A

between 9 and 18 months

34
Q

when does the posterior fontanelle close?

A

by 1 or 2 months

35
Q

which fontanelle can be closed at birth?

A

posterior fontanelle

36
Q

what is a synchondrosis?

A

cartilaginous joint where hyaline cartilage completely joins 2 bones
- immovable joint

37
Q

where are temporary synchondroses found?

A

epiphyseal plates, ilium/ischium/pubis

38
Q

where are permanent synchondroses found?

A

1st sternocostal joint

39
Q

what are the 2 parts of the Skeleton of the head?

A

neurocranium and viscerocranium

40
Q

what is the neurocranium and how many bones are part of it?

A

bony covering of brain and meninges
8

41
Q

what is the viscerocranium and how many bones are part of it?

A

facial skeleton
14

42
Q

what is the floor and roof of the neurocranium called?

A

roof = calvaria
floor = cranial base

43
Q

what does pneumatised mean?

A

air within the bones

44
Q

what vessels may rupture if there is trauma at the pterion?

A

middle meningeal artery and vein

45
Q

what is the weakest part of the skull found?
what bones meet here?

46
Q

where do spinal nerves exit vertebral canals?

A

vertebral foramina

47
Q

what is the function of the atlas?

A

helps hold up the skull

48
Q

what does the acromio- clavicular joint join?

A

appendicular to axial skeleton

49
Q

why do the bones of the spine get bigger going down?

A

holding more of the body

50
Q

what links the left and right to form a full circle at the pelvis?

A

symphysis pubis

51
Q

what is the hip joint called?

A

acetabulum

52
Q

why is the shoulder more easy to dislocate than the hip?
