MULTIPLE CHOICE
1. Where in bone are blood cells produced?
a. Haversian canal
b. Hyaline cartilage
c. Red bone marrow
d. Yellow bone marrow
ANS: C
Blood cells are produced in the red marrow of bones, especially long bones, through a process
called hematopoiesis.
2. Which term means blood cell production?
a. Hyperemia
b. Hematopoiesis
c. Remodeling
d. Ossification
ANS: B
Blood cells are produced in the red marrow of bones, especially long bones, through a process
called hematopoiesis.
3. Which term refers to the hard outer shell of a bone?
a. Compact
b. Trabecular
c. Cancellous
d. Osteoporotic
ANS: A
Compact bone constitutes approximately 80% of the total adult bone mass and forms the hard
outer shell of bone.
4. What is the central passageway of an osteon that contains the bone’s blood supply and nerves
called?
a. Haversian canal
b. Diaphysis
c. Trebecula
d. Volkmann’s canal
ANS: A
Each osteon surrounds a central canal that runs lengthwise through the bone. The central
canal, also called Haversian canal, contain blood vessels, lymphatic vessels, and nerves.
5. Which term refers to the lighter and less dense area of a bone?
a. Compact
b. Spongy
c. Irregular
, d. Sesamoid
ANS: B
Spongy bone, or cancellous bone, constitutes approximately 20% of the total bone mass, and
is lighter and less dense than compact bone.
6. Which cells destroy bone?
a. Fibroblasts
b. Osteoclasts
c. Osteoblasts
d. Chondroclasts
ANS: B
Osteoclasts are bone-destroying cells.
7. Which cells form bone?
a. Fibroblasts
b. Osteoclasts
c. Osteoblasts
d. Chondroclasts
ANS: C
Osteoblasts are bone-forming cells.
8. Which term means the process of bone development?
a. Oscillation
b. Ossification
c. Mobilization
d. Colonization
ANS: B
Ossification, or osteogenesis, is the process of bone tissue development by osteoblasts.
9. The bones in the spine are in which category?
a. Flat
b. Short
c. Irregular
d. Sesamoid
ANS: C
Irregular bones are oddly-shaped and do not fit well in other shape/size categories. Irregular
bones are found in the skull and the spine (vertebrae).
10. Which bones are small, rounded, and embedded in tendons?
a. Flat
b. Short
c. Irregular
d. Sesamoid
ANS: D
Sesamoid bones are round and usually embedded in tendons. Sesamoid bones are found in the
knee (patella), hands, and feet.
