Question

Quizplus · Accepted Answer

Large, dense-core vesicles are typically associated with the storage and release of peptide neurotransmitters, which are synthesized in the cell body and transported down the axon to the terminal. Other types of neurotransmitters, such as nonpeptides, tend to be stored in smaller, more numerous vesicles.
