A bone contains normal mineral composition but has unusually low
density and increased porosity. Which condition best matches this
structural change? -ANSWER- Osteoporosis
A cell actively secretes new bone matrix but has not yet become
enclosed within a lacuna. Which cell is present? -ANSWER- Osteoblast
A mature bone cell is found inside a lacuna and maintains the
surrounding matrix. Which cell is this? -ANSWER- Osteocyte
A cell has numerous lysosomes and is specialized for removing bone
matrix. Which cell is being described? -ANSWER- Osteoclast
A medication selectively suppresses osteoclast activity. Which skeletal
process would decrease? -ANSWER- Bone resorption
A bone continuously loses matrix because resorption exceeds
deposition. Which general process is occurring? -ANSWER- Negative
bone remodeling
,A bone gains matrix because deposition exceeds resorption. Which
general process is occurring? -ANSWER- Positive bone remodeling
A long bone is examined from its external surface inward. Which
structure would be encountered first? -ANSWER- Periosteum
The shaft of a long bone is severely damaged while its epiphyses remain
intact. Which region has been injured? -ANSWER- Diaphysis
A fracture occurs through the expanded end of a long bone. Which
region is involved? -ANSWER- Epiphysis
A growing long bone increases in length because cartilage is continually
replaced by bone at a specific region. Which structure is responsible? -
ANSWER- Epiphyseal plate
An adult has no visible epiphyseal plates because the former cartilage
has been replaced by bone. What structure remains? -ANSWER-
Epiphyseal line
A vertebra is classified by shape rather than length or width. Which
category does it belong to? -ANSWER- Irregular bone
, A rib is thin and flattened and provides protection for underlying
organs. Which bone classification fits best? -ANSWER- Flat bone
A femur is substantially longer than it is wide and contains a shaft with
expanded ends. Which classification applies? -ANSWER- Long bone
A microscope image shows concentric layers surrounding a central
canal. Which structures are visible? -ANSWER- Lamellae of an osteon
Tiny channels connect neighboring lacunae and allow communication
between osteocytes. What are these channels called? -ANSWER-
Canaliculi
A blood vessel and nerve travel through the center of an osteon. Which
structure contains them? -ANSWER- Central canal
A fracture extends into the internal cavity of a long bone containing
marrow. Which structure has been reached? -ANSWER- Medullary
cavity
A bone must expand in diameter during development. Which process
allows new bone to be added to the outer surface? -ANSWER-
Appositional growth
