Multiple choice

Which of the following processes controls the amount of neurotransmitter released from a nerve ending on a short-term, i.e. minute-to-minute basis?

  1. Actin availability

  2. Calcium inavailability

  3. Axoplasmic transport

  4. Vesicle synthesis in the cell soma

  5. Neurotransmitter synthesis

E Correct answer
Explanation

Because there is only sufficient neurotransmitter available in a nerve ending for a minute or so of continued released, the biosynthesis of new neurotransmitter to fill the recycled neurotransmitter vesicle is necessary for continued availability of neurotransmitter for release.
