Question

Identify the parts of a synapse shown below.

• A. I.Neurotransmitter receptor, II.Neurotransmitter, III.Post-synaptic membrane, IV.Neurotransmitter vesicle, V.Pre-synaptic neuron
• B. I. Pre-synaptic neuron, II. Post-synaptic neuron, III. Neurotransmitter vesicle, IV. Neurotransmitter receptor, V. Neurotransmitter
• C. I. Neurotransmitter vesicle, II. Neurotransmitter, III. Neurotransmitter receptor, IV. Pre-synaptic neuron, V. Post-synaptic neuron
• D. I. Neurotransmitter, II. Neurotransmitter receptor, III. Pre-synaptic neuron, IV. Neurotransmitter vesicle, V. Post-synaptic neuron

Answer 1

The correct option is C I. Neurotransmitter vesicle, II. Neurotransmitter, III. Neurotransmitter receptor, IV. Pre-synaptic neuron, V. Post-synaptic neuron

The image shown here is a synapse, where the pre-synaptic neuron (IV) forms a synapse with the post-synaptic neuron (V). The presynaptic neuron releases neurotransmitters (II), which are present in neurotransmitter vesicles (I) and the neurotransmitter depolarizes the post-synaptic membrane by binding to receptors on the post-synaptic membrane (III), which regulate different ligand gated ion channels.
