HUBS 191 MCQ's EXAM QUESTIONS
WITH CORRECT ANSWERS
what |type |of |bones |are |phalanges |- |CORRECT |ANSWER✔✔-long |bones
Circumduction |does |NOT |move |within |which |plane? |- |CORRECT |ANSWER✔✔-transverse- |as |
there |is |no |rotation
If |I |hold |my |hand |above |my |head, |my |elbow |is
_________ |to |my |shoulder |- |CORRECT |ANSWER✔✔-distal/inferior. |always |refer |to |body |in |
anatomical |position
what |is |required |for |longitudinal |growth |of |long |bones? |- |CORRECT |ANSWER✔✔-The |
epiphyseal |plate.
It |allows |longitudinal |growth |by |creating |new |cartilage |above |the |plate, |as |cartilage |on |the |
bottom |of |the |plate |is |turned |into
bone
What |is |the |purpose |of |a |meniscus? |- |CORRECT |ANSWER✔✔-Absorb |shock |& |spread |the |
force. |So |that |it |isn't |concentrated |in |one |spot, |which |may |cause |damage
What |class |of |joint |is |the |pubic |symphysis? |- |CORRECT |ANSWER✔✔-Cartilaginous. |
these |joints |allow |SOME |movement |(but
not |much)-The |pubic |symphysis |requires |a |little |bit |of |movement, |especially |during |childbirth
What |is |the |best |structure |for |preventing |the |tibia |from |dislocating |anteriorly? |- |CORRECT |
ANSWER✔✔-The |ACL |(anterior |cruiciate |ligament)
| Holds |the |tibia |on |its |anterior |(front) |surface.
, This |prevents |it |from |slipping |forward |from |the
knee |joint
If |the |blood |plasma |(ECF) |was |considered |hypotonic |Compared |to |red |blood |cells |(ICF), |what |
would |the |cells |look |like? |- |CORRECT |ANSWER✔✔-Cells |would |swell |
The |hypotonic |ECF |would |have |a |lower |concentration |of |solutes |(and |a |higher |concentration |
of |water) |The |water |would |want |to |move |into |the |cell |(via |osmosis), |and |would |cause |the |cell |
to |swell |up
A |bunch |of |muscle |cells |is |called: |- |CORRECT |ANSWER✔✔-a |fascicle
What |causes |the |myosin |head |move |so |that |ready |to |attach |to |a |new |site |of |actin? |- |CORRECT
|ANSWER✔✔-ATP |energy |release |into |ADP |and |Pi.
ATP |releases |energy |into |the |myosin |head, |which |causes |it |to |change |shape |& |store |energy |
(which |is
used |to |pull |on |actin).It |causes |myosin |to |detach |from |actin
Which |of |the |following |ALWAYS |increases |muscle
tension?
a. |Making |the |muscle |longer
b. |Increasing |action |potential |frequency
c. |Increasing |amount |of |muscle |cells |activated
d. |Making |muscle |cells |shorter |- |CORRECT |ANSWER✔✔-Activating |more |muscle
|cells/recruitment. |
• |There |is |an |optimal |muscle |length |- |Making |it
longer |is |only |sometimes |helpful
• |Increased |signal |frequency |only |increases |tension
until |tetanus |(maximum |tension)
