I'm new to Bitcoin and crypto in general, and I've been doing some reading to get a better understanding of how it works. and I came across "Lightning Network" and I like it, but I have some questions about some things I'm not sure about.

Does a transaction get sent to the Blockchain when you use the Lightning Network to send payment to someone you're not directly connected to via an intermediary node? Because, according to what I've read, only the first and last transaction appear in the Blockchain, I'm not sure if those involving an intermediary node will as well.
