Biology - Neural Control and Coordination Question with Solution | TestHub
Which of the following statements about electrical synapse are CORRECT.
(A). In this type of synapse gap between the neighboring neurons is very narrow.
(B). The electrical conductive link is formed between pre and post synaptic neuron.
(C). At the gap junction, the two cells are within almost 4.8 nm distance of each other.
(D). Transmission across the gap is slower, but it depends on the connection located at the gap junctions between the two neurons.
Choose thecorrectanswer from the options given below:
Options:
Answer:
Solution:
In an electrical synapse, the membranes of the pre-synaptic and post-synaptic neurons are in very close proximity, meaning the gap between them is very narrow (typically around to nm). Thus, statement (A) is correct.
Gap junctions form an electrical conductive link between the pre-synaptic and post-synaptic neurons, allowing electrical current to flow directly from one neuron to the other. Thus, statement (B) is correct.
Statement (C) is incorrect because the distance is typically to nm, not nm.
Statement (D) is incorrect because impulse transmission across an electrical synapse is always faster than that across a chemical synapse, not slower.
Therefore, only statements (A) and (B) are correct.
Answer: (A) and (B) are correct
