Question
Which one of the following statements regarding neurotransmitters at both the neuromuscular junction (NMJ) and a central nervous system (CNS) synapse is correct?Group of answer choicesBoth only release excitatory neurotransmitters.The NMJ releases a single neurotransmitter whereas multiple neurotransmitters can be released in a CNS synapse.Both only release acetylcholine as a neurotransmitter.Both only release inhibitory neurotransmitters.
Solution
The correct statement regarding neurotransmitters at both the neuromuscular junction (NMJ) and a central nervous system (CNS) synapse is: "The NMJ releases a single neurotransmitter whereas multiple neurotransmitters can be released in a CNS synapse."
Here's why:
-
It's not true that both only release excitatory neurotransmitters. In the CNS, both excitatory and inhibitory neurotransmitters are released, depending on the specific synapse and its function.
-
The NMJ does indeed release a single neurotransmitter, acetylcholine, which is excitatory and leads to muscle contraction. In contrast, the CNS can release multiple types of neurotransmitters, including both excitatory and inhibitory ones, depending on the specific neuron and synapse.
-
It's not true that both only release acetylcholine as a neurotransmitter. While the NMJ does only release acetylcholine, the CNS releases a variety of neurotransmitters.
-
It's not true that both only release inhibitory neurotransmitters. As mentioned, the NMJ releases an excitatory neurotransmitter (acetylcholine), and the CNS can release both excitatory and inhibitory neurotransmitters.
