Posterior neck muscles

There are a bunch of muscles in the back of your neck which help lift your head up. There are back muscles, and back muscles that become neck muscles, and neck muscles that are head muscles. I want to tease the big muscles apart a little bit so I can understand what's going on here better and why I might get a pain in the neck from riding my bike for long periods.

I know I can see some of these muscles on anatomical models. How many can I find and describe?
