chapter 6 - bone tissue Flashcards
what are the three sections of bone?
diaphysis, epiphysis, and metaphysis
what part of the bone does not fuse until you stop growing?
epiphyseal growth plate
what is growth in length of bone?
interstitial growth
what is the shaft of a bone?
diaphysis
what are the two ends of a long bone?
epiphysis
what is the area where the epiphysis and diaphysis join?
metaphysis
what helps reduce friction, absorb shock, and most abundant type of cartilage?
hyaline cartilage
what is the weakest cartilage?
hyaline cartilage
what is the hardness of bone dependent on?
extracellular matrix
what builds bone?
osteoblasts
what maintains bone?
osteoclasts
what are the two types of bone?
compact and spongy
what of the two bone types is stronger?
compact
what type of fracture is it where one or both bones are open to the outside?
open (compound fracture)
what type of fracture contains splintered bone, broken into pieces?
comminuted fracture
what type of fracture looks like a broken green twig?
greenstick fracture
what type of fracture is it when the distal part of the bone is saved up into the proximal part?
impacted fracture
what type of fracture occurs at the distal end of the fibula?
potts fracture
what type of fracture is a fracture of the distal radius or ulna?
colles fracture
what protects bone marrow?
spongy bone
what are the two methods by which bones grow?
thickness and length
what is appositional growth?
growth in thickness
what is interstitial growth?
growth in length
where does interstitial growth occur?
at the epiphyseal plate
which bones are greater in length than width?
long bones
what bones are cube shaped?
short bones
what bones are two parallel pieces of compact bone on the outside with a spongy center?
flat bone
what bones are complex shapes that aren’t categorized into other bones?
irregular bones (ex hipbones, vertebrae, facial bones)
what bones are shaped like sesame seeds?
sesamoid bones
what are small bones sometimes located within structures?
structural bones
