Osetoblast - ANSWERSS💫✔️-a bone-forming cell
Osteocyte - ANSWERSS💫✔️-a mature bone cell surrounded by bone matrix
Osteoclast - ANSWERSS💫✔️-a large, multinucleated cell that breaks down bone
Hematoma - ANSWERSS💫✔️-a mass of blood that is confined to an organ in some limited space
Callus - ANSWERSS💫✔️-a mass of connective tissue that connects the ends of a broken bone
Anatomical position - ANSWERSS💫✔️-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 principle agents in bone matrix, and how do they each affect the properties of bone
tissue? - ANSWERSS💫✔️-collagen- gives the tissue flexibility and tensile strength
calcium salts- (hydroxyapetite) 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? - ANSWERSS💫✔️-
osteocyte
A bone cell has more than one nucleus. What kind of bone cell is it? - ANSWERSS💫✔️-osteoclast
Looking at bone tissue under a microscope, you see no osteons. Is this compact or cancellous bone
tissue? - ANSWERSS💫✔️-cancellous bone tissue
, What kind of bone tissue contains trabeculae? What do you find in the spaces between trabeculae? -
ANSWERSS💫✔️-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? - ANSWERSS💫✔️-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? - ANSWERSS💫✔️-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 remodeled. What are they? - ANSWERSS💫✔️-1)
remodeling 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 the bone grows? - ANSWERSS💫✔️-Cartilage is ossified at the same rate in
which it is added.
The epiphyseal plate separates the diaphysis from the epiphysis. On which side of the plate does the
tissue ossify? - ANSWERSS💫✔️-the side nearest the diaphysis
If a long bone had no epiphyseal plates because they have become epiphyseal lines, is there any way
that a bone can grow? - ANSWERSS💫✔️-There is no way that the bone can grow longer. However, it can
grow in width if the osteoblasts lay new bone matrices on top of the old one.
What is appositional bone growth? - ANSWERSS💫✔️-When osteoblasts lay new bone matrices on the
surface of the bone and the bone grows in diameter.
