Question

A diagram showing axon terminal and synapse is given. Identify correctly at least two of A-D

• A. A - Receptor
  C - Synaptic vesicles
• B. B - Synaptic connection
  D - K⁺
• C. A - Neurotransmitter
  B - Synaptic cleft
• D. C - Neurotransmitter
  D - Ca⁺⁺

Answer 1

The Correct Option is A

The question requires identifying components of an axon terminal and synapse from a provided diagram. Let's analyze the given options and match them with parts of the diagram:

1. The axon terminal is part of the neuron that connects to the synapse and contains the synaptic vesicles.
2. Synaptic vesicles (labeled as C in the diagram) are small structures that store neurotransmitters and release them into the synaptic cleft.
3. The receptors (labeled as A in the options) are structures on the dendrite of the post-synaptic neuron that interact with released neurotransmitters.

Based on these identifiers, the correct answer is:

• A - Receptor: These bind with neurotransmitters.
• C - Synaptic vesicles: These store and release neurotransmitters within the axon terminal.

Thus, the parts A and C align accurately with the components labeled in the provided axon terminal and synapse diagram, confirming the answer as correct.
