Something baffles me about how most people study for anatomy lab: When you study for histo and path, you don't study from artistic renderings of tissue sections. You study photographs. So why study from artistic renderings of anatomical structures? I like Netter, and all, but I'd rather study Rohen.
Go to lab, but buy and study from Rohen. These are the most beautifully dissected bodies you'll ever see. And that's the kind of stuff that you'll be tested on.
And DO NOT, DO NOT stay until 7 pm digging through structures. You'll be taking away from actual study time to do, basically, scut work. This is a sure set up for failure.
But yes, you'll get used to the dead bodies, and you stop being worried that they'll suddenly reach up and grab your shoulder.
