There are a lot of intramuscular injections occurring right now into the deltoid muscle around the world (future people: check the date) and it was recommended that I take a look at the anatomy here and structures that might be at risk from damage by a needle to help out those people holding the needle.

The deltoid muscle is a safe site for intramuscular injections, so let's get a good visual sense of what's nearby.
