Osteoblast - ANSWERS-a bone-forming cell
Osteocyte - ANSWERS-a mature bone cell surrounded by bone
matrix
Osteoclast - ANSWERS-a large, multinucleated cell that breaks
down bone
Hematoma - ANSWERS-a mass of blood that is confined to an organ
in some limited space
Callus - ANSWERS-a mass of connective tissue that connects the
ends of a broken bone
Anatomical position - ANSWERS-the position acquired when one
stands erect with the feet facing forward, the upper limbs hanging
at the sides, and the palms facing forward with the thumbs to the
outside.
What are the two principal agents in bone matrix, and how do they
each affect the properties of bone tissue? - ANSWERS-collagen-
gives the tissue flexibility and tensile strength
calcium salts- (hydroxyapatite) gives the bone tissue hardness and
its compressive strength
, A bone cell is completely surrounded by bone matrix. What kind of
bone cell is it? - ANSWERS-osteocyte
A bone cell has more than one nucleus. What kind of bone cell is it?
- ANSWERS-osteoclast
Looking at bone tissue under a microscope, you see no osteons. Is
this compact or cancellous bone tissue? - ANSWERS-cancellous
bone tissue
What kind of bone tissue contains trabeculae? What do you find in
the spaces between trabeculae? - ANSWERS-In cancellous bone
tissue. In the spaces between trabeculae, you find red bone marrow
and blood vessels.
What is the term for the layers of tissue that form an osteon? What
is the term for the layers of tissue between osteons? - ANSWERS-
The term for the layers of tissue that form an osteon is concentric
lamellae. The term for the layers or tissue between osteons is
interstitial tissue.
What are canaliculi? - ANSWERS-extensions of osteocytes which
allow the cells in bone tissue to communicate with one another
There are at least 6 reasons bone must be continually remodelled.
What are they? - ANSWERS-1) remodelling of cancellous bone to
produce more compact bone
2) bone mass- changes in response to stress they experience
3) replace worn out bone and cartilage
4) bone repair/fracture
5) bone re-shaped to meet needs of body
6) calcium levels in your body are regulated by osteoclasts
Bone growth occurs when new cartilage is added to the bone's
epiphyseal plate. Why doesn't the epiphyseal plate get thicker as
