The science section can vary in all honesty. It can be very general to specific. But, to answer your question yes it can have questions asking you to identify such things as blood vessels or tissue layers, but not so much the nerves (imo). Also, keep in mind the science section isn't limited to A&P, so be sure to brush up on your biology and chemistry if you haven't done so already.
In terms of A&P, I watched videos on YouTube covering all 11 systems to refresh my memory, starting from my weakest to strongest. Helped me big time.
