a) the potassium (k+) and sodium (na+) ions are in balance.
b) there are large amounts of potassium (k+) ions inside the cells.
c) there are large amounts of sodium (na+) ions inside the cells.
question 5 (mandatory) (2 points)
list any two (2) generic drugs from the cholinergic blockers section in chapter 13.

Explanation:

For Question 4: At rest, a neuron has a high concentration of potassium ions inside the cell. The balance of potassium and sodium ions is not equal at rest. Sodium ions are more concentrated outside the cell at rest.
For Question 5: Common cholinergic blockers include atropine and scopolamine.
