A 12-year-old male patient comes in
complaining of leg pains, difficulty
walking in a straight line as well as a
limp that has gotten worse. As a
child, he was in an accident leading
to a broken leg. Upon x-ray, it is
determined there is a difference in
the length of the femur. What is most
likely the initial injury that has led to
this abnormality?
a.The patient broke the shorter leg
on the epiphyseal plate.
b. The patient broke the longer leg
on the periosteum.
c. The patient broke the longer leg
on the epiphyseal plate.
d. The patient broke the shorter leg
on the diaphysis.
e. The patient broke the longer leg in
the diaphysis
b
Jake has rising calcium levels in the
blood. What should happen to bring
his calcium level back to normal
homeostasis?
a. His parathyroid gland should
secrete more calcitonin
b. His thyroid gland should secrete
more calcitonin
c. His parathyroid gland should
secrete less calcitonin
d. His thyroid gland should secrete
less calcitonin
a
In Jake's case, what is responsible
for releasing calcium from the bone
into the blood stream in the first
place?
a. Osteoclasts
b. Osteocytes
c. Osteoblasts
d. Chondrocytes

-will want to release ADP as quickly as it can
-therefore, ATP can reattach more times in a given amount of time
The myosin heads are replaced with
a different structure. Everything is
the same but the myosin head's
affinity for ADP is lower. What is the
effect on the overall number of
contractions in a given time (not just
one contraction)?
a. The myosin head would not attach
to the actin, meaning no muscle
contractions would occur.
b. Fewer muscle contractions would
occur.
c. More muscle contractions would
occur.
d. No changes would happen.
c
What allows actin and myosin to
bind together and create a
contraction?
a. Myosin has actin binding sites,
and the entire myosin structure
moves along to create a contraction.
b. Actin has myosin binding sites,
and the entire myosin structure
moves along to create a contraction.
c. Actin has myosin binding sites, so
a myosin head binds to actin. If a
contraction occurs, the actin
filaments are pulled by the myosin
head.
d. Either Actin or myosin can bind to
each other and create a contraction.
epiphyseal plate
where does bone growth occur?
what happens at the epiphyseal plate cartilage cells undergo mitotic, enlarge then die
during bone growth?
what would happen if epiphyseal bone growth will not occur and will result in a shorter bone
plate was broken?
inhibits osteoclast activity to prevent calcium from being released from
calcitonin bone to bloodstream
