ELI5: Explain Like I'm 5

Neurotransmitter vesicle

Imagine you have a toy box full of little colored balls that you play with every day. These balls represent chemicals called neurotransmitters in your body. Your brain uses these neurotransmitters to help your body talk to itself and work properly.

Now, imagine that you put some of these balls in special containers (like Tupperware), but instead of putting them inside a toy box, they remain inside tiny bubbles called vesicles. These vesicles are like little packages in your brain that keep the neurotransmitters safe until they are needed to send messages to different parts of your body.

When your brain wants to use one of these neurotransmitters, it sends a signal to the vesicle, telling it to open up and release its special colored ball. This release of neurotransmitters creates an electrical message that travels through your nerves, allowing your body to talk to itself and complete essential tasks.

Just like how you put your toys away in a specific spot in your toy box, vesicles release neurotransmitters in specific areas of your brain and nervous system so that they can communicate with the right parts of your body. This helps your brain and body work together like a well-oiled machine.
