1
Q
2 main sections in long bones
A
2 epiphyses (ends) 1 diaphysis (long shaft)
2
Q
where is the metaphysis (section where majority of bone growth occurs)
A
between diaphysis and two epiphyses
3
Q
where is the articular/hyaline cartilage (cartilage that allows bone to articulate)
A
on the ends/outside of the epiphyses
4
Q
what is the outer layer of long bones called
A
periosteum (made of collagen)
5
Q
what is the diaphysis/shaft of long bone made of predominantly
A
compact bone
6
Q
what is the purpose of the medullary cavity
A
filled with yellow bone marrow
7
Q
what are the epiphyses made up of
A
spongy/cancellous bone
contains a lot of red blood marrow
8
Q
what are the epiphyseal/growth plates
A
layer of cartilage within a growing bone where bone growth takes place
