In a condition known as Tetradotoxin, the level of calcium ions in the blood and interstitial fluid is lower than normal. How would this condition affect the function of the nervous system?
A. cholinergic synapses would be more active
B. neurons would generate action potentials spontaneously
C. less neurotransmitter would be released from a presynaptic membrane in response to an action potential
D. depolarizing events would occur more frequently at the postsynaptic membrane
E. potassium channels would fail to open
