yeah...histology was a pretty good course. i took it in undergrad last spring. lecture was pretty straightforward, just with tons of details to keep straight... lab was a bit tougher as it seemed my professor purposely chose slides that had to have come from pathology or something...they were horrible. knowing the characteristics of different regions makes it helpful in lab...such as when you see ciliated psuedostratified columnar epithelium...there's only certain places it will be and if you know certain other things to look for such as hyaline cartilage--life becomes much easier! my professor was like a drill instructor in teaching us this stuff but she provided some amazing resources for us to utilize in our studies... there are some med schools that offer great online quizzes for histo--i highly recommend looking for these--i think iowa had a pretty good one. the thing about histo is just details, details, details! i found it fairly fun though, except for the lab exams ;-) good luck if you're taking it over summer :-D
