    A particular disease of the nervous system specifically involves the\[C{{a}^{2+}}\] ion channels at the chemical synapses of motor neurons where neurotransmitter is stored and released. In other words, this disease affects the

    A) Axon terminals of the presynaptic cell and the release of acetylcholine.

    B) Axon terminals of the postsynaptic cell and the release of \[{{K}^{+}}\] ions.

    C) Electrical synapses.

    D) Axon terminals of the presynaptic cell and the release of \[{{K}^{+}}\] ions.

    Correct Answer: A

    Solution :

    [a] If the disease acts on a chemical synapse where the neurotransmitter is stored and released, it is affecting the axon terminals of the presynaptic cell. \[C{{a}^{2+}}\]channels are involved in regulating the release of acetylcholine by allowing \[C{{a}^{2+}}\] to enter the presynaptic cell and promoting the fusion of acetylcholine containing vesicles to the membrane.
