ELI5: Explain Like I'm 5

Dendrite

A dendrite is like a tree branch that grows out of a brain cell. It helps the brain cell talk to other brain cells by receiving signals or messages from them. Think of it like a telephone wire that brings a message to your friend's phone from your phone when you want to talk to them. But in the case of the brain, the dendrite receives these messages from other brain cells and helps the brain figure out what to do next. So, it's like a tiny branch that helps your brain cells communicate and work together to help you learn, think and do all the things you do every day!
