Exocytosis Animation (with a real Paramecium!)

Exocytosis occurs when a cell needs to get rid of something that is too big to get through the membrane. During exocytosis, a vesicle containing the stuff that the cell wants to expel moves to the membrane and fuses with it. As you can see, this allows the stuff out. Cells do exocytosis to get rid of large waste particles, or to secrete proteins or hormones (like insulin, for example) that need to be released outside of the cell.
Here is an example of a real Paramecium (a small pond water organism), doing exocytosis.

How many types are endocytosis?

[@BioManBiology]

Sorry, I'm not entirely clear about your question. The video here is about exocytosis. I have another video about endocytosis you might be interested in here: ruclips.net/video/0hbkwyZccQI/видео.htmlsi=mlD8Uy4QxjTyDdBa
Hopefully, that helps!

How does exocytosis work in the case of neurotransmitters

[@BioManBiology]

Essentially the same way. Neurotransmitters are stored in vesicles near the end of the axon. They are released via exocytosis, much in the same way as illustrated by the video. I hope that helps!

[@BioManBiology]

Essentially, in the same way. Neurotransmitters are stored in vesicles near the end of the axon. They are released by exocytosis as shown in the video when a nerve impulse reaches the end of the axon. I hope that helps!
