foramen
a ______ is a rounded opening through a bone
fossa
a _______ is a flattened or shallow surface on a bone
simple fracture
a bone that is broken but does not pierce the skin is a
false
an impacted fracture means that the bone was not broken the whole way through
true
children and adults require about the same amount of daily calcium
false
compact bone is the main bone tissue found in the epiphyses of long bones
hyaline cartilage is replaced by bone
during endochondral ossification
bone develops between sheets of fibrous connective tissue
during intramembraneous ossification
limb bones of an adolescent would have growth plates adults would not
how could you differentiate between the skeletons of a tall adolescent and a short adult
false
once a person reaches adulthood, they no longer form new bone
true
osteoblasts are the cells that secrete the organic matrix of bone
lacunae
osteocytes live in small spaces within the calcified bone called
produces blood cells and is located in spongy bone
red marrow
reduction
repair of a bone fracture is called
true
spongy bone is not as strong as compact bone
appositional growth
the addition of new bone on top of existing bone to increase bone thickness is called
epiphysis
the end of a long is the

yellow marrow
the medullary cavity contains
diaphysis
the shaft of a long bone is the
