Video transcript

Hey, everyone. Let's take a look at this question. Together. The synaptic cleft functions as a junction or small gap at which neurons communicate with each other. In which part of the neuron is the synaptic cleft usually found. Is it answer choice? A inside the axon answer. Choice B between two dendrites. Answer choice c between the axon and the dendrites or answer choice. D none of the above. Let's work this problem out together to try to figure out which of the following answer choices is the location for the synaptic cleft within a neuron. So in order to solve this question, we have to recall what we have learned about the synaptic cleft as well as the parts of the neuron to determine where the synaptic cleft is usually found. Of which we note that the synaptic cleft, which is also a junction or small gap is also referred to as the synaptic gap. And since the synaptic gap or synaptic cleft is the location where the neurons communicate with each other. The synaptic cleft is usually formed between the axon term and the dendritic spines. Therefore, the synaptic cleft is usually found between the axon and the dendrites, which is answer choice C the correct answer and all other answer choices are incorrect. Since the synaptic cleft is found between the axon and the dendrites which allows the neurons to communicate with each other. So answer choice C is the only correct answer choice. I hope you found this video to be helpful. Thank you and goodbye.
