Question

use the following information to answer question 10. 10. match the labelled synapse structure with the correct structure or function. place the correct number in each blank. use each answer only once. postsynaptic membrane; of the dendrite; \after\ the synapse mitochondria; supply atp for synthesis of transmitters synaptic cleft; the synapse; a gap presynaptic membrane; of the axon; \before\ the synapse receptor site for the neurotransmitter (dendrite) neurotransmitter; the chemical messenger acetylcholinesterase; an enzyme that breaks down ach (acetylcholine) synaptic vesicle containing the neurotransmitter ach (acetylcholine) neurotransmitter released by exocytosis from a vesicle axon terminal; the axon knob 1. structure b 2. structure a 3. structure e 4. structure c 5. structure h 6. structure j 7. structure g 8. structure d 9. structure f 10. structure i

Explanation:

1. The postsynaptic membrane of the dendrite is the red - colored part on the left side which is Structure J.
2. Mitochondria are the green - like structures in the axon terminal which is Structure B.
3. The synaptic cleft is the gap between the axon and the dendrite which is Structure E.
4. The presynaptic membrane of the axon is the blue - colored part at the end of the axon which is Structure A.
5. Receptor sites for neurotransmitters on the dendrite are the green - triangular shapes on the red part which is Structure G.
6. Neurotransmitters are the small particles in the synaptic cleft which is Structure F.
7. Acetylcholinesterase is not clearly shown in the diagram but if we assume it's in the synaptic cleft for breaking down ACh, we can't match it exactly from the given structures.
8. Synaptic vesicles containing ACh are the pink - colored circular structures in the axon terminal which is Structure C.
9. Neurotransmitter released by exocytosis from a vesicle is also Structure F as it represents the neurotransmitter in the synaptic cleft after release.
10. The axon terminal (axon knob) is the end part of the axon which is Structure A.

Answer:

1. Structure J
2. Structure B
3. Structure E
4. Structure A
5. Structure G
6. Structure F
7. No match from given structures
8. Structure C
9. Structure F
10. Structure A
