Hey, everyone. Let's take a look at this question together which neurotransmitter is primarily utilized by the upper motor neurons to transmit signals. Is it answer choice? A acetylcholine answer choice B, glutamate, answer choice C norepinephrine or answer choice D adenosine. Let's work this problem out together to try to figure out which of the following answer choices is the neurotransmitter primarily utilized by the upper motor ne neurons to transmit signals. So in order to solve this question, we have to recall what we have learned about the upper motor neurons and which neurotransmitter they primarily utilize to transmit signals. And we know that when we are talking about the upper motor neurons, particularly the upper motor neurons involved in the corticospinal pathway, they primarily use the neurotransmitter glutamate, which we know that glutamate is the main excitatory neurotransmitter in the central nervous system or CNS. And glutamate is involved in the transmission of signals that initiate and execute voluntary movements. So the neurotransmitter primarily utilized by the upper motor neurons to transmit signals is answer choice. B, glutamate and all other answer choices are incorrect. I hope you found this video to be helpful. Thank you. And Goodbye.
