Question

Which one of the following is a wrong statement?

I. Neurotransmitter jumps from one junction to another.
II. After signal transmission postsynaptic membrane is destroyed.
III. Neurotransmitter remains unaltered after the transmission of nerve impulse.

• A. I and III
• B. II and III
• C. I and II
• D. None of these

Answer 1

The correct option is B II and III

Option B is right.

Neurotransmitter jumps from one junction to another, But one cell doesn't actually touch another, and the signals can't jump across the tiny spaces in between. To cross those tiny gaps, called synapses, they rely on chemical messengers. These chemicals are known as neurotransmitters. And their role in cell talk is called neurotrans mission.
