As a piece of wood, I serve many purposes Made out of flesh, I am an exercise Some also know me as an importat aspect of an argument In all thre cases, I am a basic building block

I've a barrel but no lid Silver keys but no lock. Should you ever use me, You'll find it hard to talk. I've a bell but no clapper, I can sing a magnum opus, But the best hint of all Is a salty, dry octopus.

Hanging or standing, I’m at least one star. I reveal the space, if that’s where you are. My neurons connect, I’ve got an idea! Uh oh, I’m missing. Do you feel that? It’s fear.
