(A) increases the sensitivity of the postsynaptic membrane to acetylcholine.
(B) increases the release of substances that cause the hyperpolarization of the neurons.
(C) stimulates the activity of acetylcholinesterase in the synaptic cleft.
(D) makes the membrane permanently impermeable to sodium.

53. A drug might act as a stimulant of the somatic nervous system if it
(A) increases the sensitivity of the postsynaptic membrane to acetylcholine. 刺激型
(B) increases the release of substances that cause the hyperpolarization of the neurons.  應該是去極化? 不太確定QQ
(C) stimulates the activity of acetylcholinesterase in the synaptic cleft. -> ACh被AChEI快速幹掉 抑制型
(D) makes the membrane permanently impermeable to sodium. Sodium blocker常做抑制劑 (E.g. Lidocaine)
(E) increases the sensitivity of the presynaptic membrane to acetylcholine. ACh受體在突觸後

Acetylcholine受體在突觸後(畢竟要往後面傳) 突觸後受器微整理
1. Chemical synapse 就是本題提到的ACh OwO
2. Electrical synapse 用Gap junction連結/維持強度，存在神經元和神經元/Glial cells 間
