Endo. Ossification
Bone Repair and Fractures
100
classification that describes bones found in the cranium
What are flat bones
100
the functional microscopic unit of compact bone
What is an osteon
100
type of bone intramembranous ossification occurs in
What is flat bone
100
type of bone created
What are long bones (mostly everything but flat bones)
100
only occurs in children, bending of the bone
What is greenstick fracture
200
cells responsible for resorption
What are osteoclasts
200
lines the medullary cavity
What is endosteum
200
these cells give rise to osteogenic stem cells
What is mesenchymal cells
200
type of tissue that creates the model of bone at the beginning of endochondral ossification
What is hyaline cartilage
200
many broken fragments
What is comminuted
300
an opening in bone through which blood vessels and nerves pass
What is a foramen
300
concentric layers of compact bone
What are lamellae
300
osteoblasts must travel to this are in order to create the compact bone on the sides of flat bone
What is periosteum
300
area of primary ossification
What is the middle of the center of the long bone (medullary cavity)
300
a complete break at a diagonal angle that is sticking out of the skin
What is an open displaced oblique fracture
400
an oblong projection for muscle attachment that resembles a rounded bump
What is a tuberosity
400
shaft of a long bone
What is the diaphysis
400
branches of spongy bone found in the middle of flat bone
What are trabeculae
400
bone building cells that create bone after they move into the cartilage model via blood vessels
What are osteoblasts
400
three ways fractures are classified
What are open vs. closed, complete vs. incomplete, displaced vs. non-displaced
500
red bone marrow is responsible for this
What is hematopoiesis
500
the site of secondary ossification on the long bone structure where growth occurs throughout childhood until maturity
What is the epiphyseal plate
500
the type of tissue that begins the process of intramembranous ossification
What is fibrous connective tissue
500
this happens around/after birth at the epiphyseal plate
What is secondary ossification
500
the steps of bone repair
What is hematoma formation due to broken blood vessels, spongy bone formation due to osteoblasts moving in via blood vessels, phagocytic cells clean up damaged tissue, fibrocartilage builds cartilaginous callous which is transformed into bony callous as cartilage breaks down, osteoclasts remodel bone to original size
