Which of the Following Is a Potential Consequence of Blocking

Which of the following is a potential consequence of blocking the neurotransmitter from reaching the receptor site?

A) The nerve will produce a different type of neurotransmitter that does not get blocked from the receptor site.
B) The nerve impulse will increase in strength as the levels of neurotransmitter build up at the synapse.
C) The receptor sites will be filled with a different neurotransmitter allowing for a new muscle contraction to take place.
D) The muscle or gland that was supposed to receive the nerve impulse will fail to activate.In the case of the muscle it will not contract.If it is a gland it will not secrete its product.
E) The muscle or gland that was supposed to receive the nerve impulse will build up its threshold for activation.Once the threshold is reached the muscle will have a massive contraction while the gland will over secrete its product.
