What muscles are involved to sit on the edge of the bed and lie down. And then to roll onto side and push up and stand up? Thanks

Many of them. There are muscles in the back, the legs, the bottom, the belly... and even the arms and neck as you try to balance. Your question is very broad. I'm sure people here want to try to help, but maybe you could be more specific or share why you're asking? Perhaps you only care about very precise types of movements?

 

The movements you mention tend to incorporate muscle action from across the entire body so it's difficult to give you a precise answer or list of specific muscles.
