Why is it important for neurons to maintain a stable resting membrane potential (RMP)? (3 points)

A neuron is exposed to a poison that prevents chemical-gated K+ channels from binding to the chemical that normally activates them. What is one result that may occur? (Assume that this particular neuron does not contain any chemical-gated Cl- channels) (3 points)

In the above image, a graded potential in neuron 2 is likely stimulated by __________________________ .

Using the specific circuit shown above, which neuron is associated with the dorsal root?

Afferent neurons carry electrical signals toward the central nervous system. (2 points)

If a graded (local) potential raises voltage (depolarization) above threshold, this will prevent the cell from beginning an action potential. (2 points)

In a multipolar neuron, these multiple branched processes are found attached directly to the soma (cell body) of the neuron and function to receive a signal from another neuron.

A drug binds to potassium voltage-gated channels and prevents them from opening. Which of the following statements is TRUE in this scenario? Assume the cell is starting at resting membrane potential (RMP) of -70mV.  (3 points)

Which of the following is the type of connective tissue that surrounds an entire nerve. (2 points)

Which of the following functional classes of neurons is found entirely within the CNS (does not enter / exit periphery)?
