How are secretory vesicles produced?

Secretory vesicles form from the trans Golgi network, and they release their contents to the cell exterior by exocytosis in response to extracellular signals. The secreted product can be either a small molecule (such as histamine) or a protein (such as a hormone or digestive enzyme).

What are secretory vesicles and where are they made?

Secretory vesicles

Synaptic vesicles are another example of a secretory vesicle, and they are present at the end of nerve cells (neurons). These vesicles help transmit signals from one nerve cell to another by releasing or secreting neurotransmitters that activate receptors in the next cell along.
