· In our skeleton there are 206 bones.
· All Bones are originally cartilage when we were in the
womb, and then over a period of years it gradually
turned into hard bone. This is called ossification.
· Cartilage is like an elastic tissue but it is firm and
rubbery. It also covers the ends of bones in a joint to
allow movement with minimal friction.
In this picture we can see that the
cartilage is worn down in this hip
joint causing pain when it moves.
· There are 5 types of bone in the body. These are are
long bones, short bones, flat bones , irregular and
sesmoid bones.…read more
STRUCTURE OF BONE
The Epiphysis forms the rounded ends of the large
The Diaphysis is the long central shaft.
The Metaphysis is the area between the Diaphysis
and the Epiphysis either end of the bone.
The Epiphyseal plates are plates of cartilage (or
growth plates) which allow long bones to grow in
childhood. When we stop growing at 18-25 years old
the plates stop producing cartilage cells and are
replaced by bone.
Hyaline cartilage covers the end of the bones where
they form a joint with another bone. It is a firm type of
cartilage which provides shock absorption to the
· As the name suggests long bones are literally some of
the longest bones in our body. These include the
Femur and Humerus.
· The classification of a long bone is when the bone is
longer that it is wide with growth plates at either end
(epiphysis), they have a hard outer surface of compact
bone and a spongy inside known as the cancellous
bone containing bone marrow.
· The ends of the bone are covered in cartilage to help
protect the bone and aid shock absorption.…read more
