Neural Control And Coordination Question 6
Question: 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
Options:
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.
Show Answer
Answer:
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.
