comprise?
Chapter 43 – The Nervous System
52. Genetic studies have found that Charcot-Marie-Tooth may be caused by a mutation in the
gene Mitofusin-2 (MFN2), which causes mitochondria to form large clumps. In what area of a

disease? From the following, choose the best responses to complete the sentences:
“Physiological function requires that multiple cells work together. Various defects in

The word hyponatremia derives from the words hypo (“under” or “less”)
and natrium (“sodium”). The word natrium is the basis for the abbreviation
Na for sodium. Hyponatremia is a rare condition, but has become of
more concern with the rise in amateur runners participating in marathons.
Since they run slower, they spend longer on the course and have more
opportunity to drink water and sweat out additional sodium.
Chapter 43 – The Nervous System
58. Marathon runners are encouraged to stop at water stations along the course to stay
hydrated. However, occasionally a runner drinks too much water and suffers from
hyponatremia, or “water intoxication”. While water itself is not toxic, drinking too much can
upset ion balance in the extracellular space. Based on what you know about ions and nerve
signaling, the levels of which important ion are most likely to be disrupted in hyponatremia?

A typical AA battery has a potential of 1.5V. One can think of the potential
in a neuron as having similarities to that of a battery.
