The potential difference across a resting neuron in the human body is about 100.0 mV and carries a current of about 0.580 mA. How much power does the neuron release?
µW?
Homework Answers
Here ,
Potential across neuron , v = 100 mV
current , I = 0.580 mA
I = 5.8 *10^-4 A
power released by neutron = V* I
power released by neutron = 100 *10^-3 * 5.8 *10^-4
power released by neutron = 5.8 *10^-5 W
power released by neutron = 58 uW
the power released by neutron is 58 uW

A neuron has a resting membrane potential of -70 mV; it’s trigger threshold for firing an action potential is -50 mV. Two competing signals arrive simultaneously in the trigger zone: one is a depolarizing stimulus of +40 mV, the other a hyperpolarizing stimulus of -25 mV. Will the neuron fire an action potential after integrating these signals? Why?
The neuron has a resting potential of – 60 mv and a threshold potential at -40...
The neuron has a resting potential of – 60 mv and a threshold
potential at -40 mv. The ENa is approximately at +40 mv. In every
case, the stimulus is initiated at 2 ms, and lasts for 1 ms. Draw
the membrane potentials from 0 to 10 ms for the following scenarios
in each of the boxes above.
a) 15 mv depolarizing stimulus
b) 25 mv hyperpolarizing stimulus

Many cells in the human body maintain an electric potential difference across their cellular membranes, typically through the use ion-specific pumps and channels that generate an excess of negative charges on the inside of the cellular membrane and an excess of positive charges on the outside. Let us estimate the total energy stored in the human body by this type of charge separation. Part a Different cells can have vastly different cell sizes; but as an approximation, let us assume...
