Question

Quizplus · Accepted Answer

Neuropeptides are transported along the axon by slow axonal transport, which occurs at a rate of about 40 centimeters per day. This slow rate of transport is due to the fact that the neuropeptides are primarily transported by cytoskeletal elements, which move slowly within the axon. This allows for the efficient delivery of neuropeptides to the synaptic buttons over a relatively long period of time.
