In 1983, a young boy named Jimmy Tontlewicz fell through a hole in the ice on a lake in Minnesota. When the rescue team pulled him out of the water 20 min later, his body temperature had fallen from the normal 37 C to 29 C. Calculate the sign and the magnitude of the change in the resting potential of Jimmyâ??s neurons if the ion concentrations inside and outside his axons and ion conductances are given in the table. Give your answer in mV.

Table given:
Ion g (S cm-2) Conc. inside (mM) Conc. out (mM)
Na+ 0.12 x 10-6 60 440
K+ 2.6 x 10-6 390 15
Cl- 1.3 x 10-6 65 510

#### Solution Summary

This solution reiterates the sign and the magnitude of the change in the resting potential of this case if the ion concentrations inside and outside his axons and ion conductances are given in the table.
