osteogenic cell

located in the periosteum and endosteum

osteoblast

osteoblast

make bone’s matrix called osteoid

osteoblast

get trapped and become osteocytes

osteoblast

located on the periosteum and epiphyseal plates

osteocyte

mature bone cells

osteocyte

located in compact bone and spongy bone

osteocyte

perform daily functions of bone

osteoclast

clean away bone

osteoclast

located on the periosteum and endosteum 

osteoclast

used during fracture repair and bone growth (clean away old bone from the medullary cavity)

partial

a break that doesn’t go through the bone completely

complete

a break that goes completly through the bone

open

a fracture in which the bone goes through the skin and can be seen through the outside

closed

a fracture that does not break the skin; also known as a simple fracture

Non-displaced 

a break in which the two broken ends of the bone are still lined up and have not moved out of place

displaced

a break in which the two broken ends of the bone are NOT lined up and are moved out of place (need to be set)

transverse

breaks that occur in a straight line across the bone

oblique

a break that occurs at a diagonal angle across the bone

greenstick

occurs in children; a partial fracture that causes the bone to bend

impacted

the broken ends of the bones are jammed together by the force of the injury

comminuted

intense trauma causes the bone to be broken into at least 3 pieces with many fragments at the fracture site

segmental

the same bone is broken in 2 places, causing a “floating” segment of bone between the two breaks
