Solution

The correct option is A

Pre-synaptic neuron


The correct option is A:

Explanation of the correct option:

Pre-synaptic neurons contain synaptic vesicles. These synaptic vesicles contain neurotransmitters that are released into the synaptic cleft in response to stimulation and subsequently interact with the receptors of the post-synaptic neuron.

Explanation of the incorrect options:

Option B:

Post-synaptic neurons do not contain any synaptic vesicles but it contains receptors on the post-synaptic neuronal membrane to detect the neurotransmitters released by the pre-synaptic neuron.

Option C:

A synaptic cleft is a gap or junction between pre-synaptic and post-synaptic neurons. It does not have any synaptic vesicles.

Option D:

It is an incorrect option because option A is correct.

Final answer: Synaptic vesicles are found in the pre-synaptic neurons.
