Bone Fractures
Partial bone break that typically happens in children
Greenstick
the "foremen" of the cell. Maintain healthy bone structure
Osteocytes
bone that's longer than it is wide
long bone
type of bone that surrounds the outside of all bones. also known as cortical
compact bone
Four steps of bone repair
1. Hematoma forms
2. Fibrocartilaginous callus forms
3. osteoblasts form spongy bone replacing fibrocartilaginous callus
4. Bone remodeling of compact bone
simple fracture
horizontal/clean break across the bone
osteoblasts
build and construct bone
bone that's mostly made of spongy bone and is as wide as it is long
short bone
the canal in the middle of each osteon for nerves and vessels
haversian/central canal
how many bones in the human body
206
break that exits the skin also known as open fracture
compound fracture
Osteoclasts
absorb bone tissue
often has a bit of a curve, made of mostly compact bone
flat bones
tiny bone struts in spongy bone
Which is not a function of the skeletal system?
Blood Cell formation
Hormone production
Muscle contraction
Muscle contraction
when too much torque causes a circular break
spiral fracture
when bone develops by replacing cartilage
Endochondral ossification
highly specialized in shape and structure
irregular bone
basic structural unit of compact bone
osteon
what process do osteoclasts start? it puts calcium and phosphate back into the blood stream
resorption
comminuted fracture
when bone breaks into fragments
when bones develop from a fibrous membrane (Clavicle and skull bones)

what tissue types make up the skeletal system?
connective
