name the types of bones
long bone, short bone, flat bone, irregular bone, sesamoid bone
what are the 3 parts of the long bone?
epiphysis, diaphysis and the epiphyseal plate/line
describe the characteristics of the epiphysis
has Red marrow which is also found in the adjacent parts of the diaphysis
Blood cells -responsible for the blood cell production
Highly vascularised
describe the characteristics of the diaphysis
has yellow marrow - contains a high amount of stem cells
Fat, cartilage, bone
Less vascularized
what is the epiphyseal plate/line
Epiphyseal line/plate are basically sections of cartilage at the ends of long bones - plays an important role in bone growth
