major parts of a long bone Flashcards
what is the proximal epiphysis
end of the bone where things connect to, has spongy bone, proximal is closest to mid line of body
what is the growth plate
part of bone that allows for room to grow, in the epiphysis, inbetween spongy bone
what is spongy bone
part of the inside of bone that is on the ends of bones(inside)
what is the periosteum
the outside hard part of the bone(cannot peel off) is hard
what is the endosteum
the lining in the inside of bone on inside then goes cavity of bone
what is the diaphysis
the middle portion of the bone that has compact bone
what is the medullary cavity
the hollow space inside of bones, filled with marrow
what is marrow
the stuff inside of the bone cavity( red marrow produces blood, yellow marrow is fat) as you get older red marrow gets replaced with yellow marrow
are there blood vessels inside of the bones
yes, bones have a very good blood supply, create blood cells,
what is compact bone
the very thick and hard part of bone(in-between periosteum and endosteum) is in the diaphysis
what is the distal epiphysis
end of the bone that is far away from the midline of the body(filled with spongy bone and has growth plate)
What is an osteon?
circular tube of the long bone
What is a halversian canal
the vertical opening where the blood vessels and nerves go through in the long bone
What is one type of bone and characteristics and example
Long bone, long middle with expanded ends, femur
What is one type of bone and characteristics and example
Irregular bone, variety of different shapes, mostly connected to several other bones, vertebrae
