Which type of neuron is most likely to contain mechanically-gated Na+ channels in its dendrites? (2 points)

Once a neuron reaches threshold membrane potential, the action potential can only travel in one direction, towards the axon terminals. (2 points)

During normal physiology, if the normal body temperature falls below the set point of 98.7 degrees Fahrenheit, the body responds by instituting measures to raise its temperature, including shivering and constricting superficial blood vessels to hold on to more heat. This is an example of a __________________ feedback loop.

When considering the electrochemical gradient of sodium ions, the electric gradient counteracts (is opposite) the chemical gradient of the ion. (2 points)  

Which type of membrane proteins are required to establish a resting membrane potential? Choose all that apply. (3 points)  

When considering the electrochemical gradient of potassium ions, the electric gradient counteracts (is opposite) the chemical gradient of the ion. (2 points)

After the resting membrane potential is established, sodium is more concentrated ____________ of the cell. (2 points)

Once a multipolar neuron reaches threshold membrane potential, the action potential can travel from the cell body towards the axon terminals, OR from the axon terminals back towards the cell body. (2 points)
