I’m a visual learner and this helped me understand much better! Thank you Dr!!

Your channel is a treasure! It's so pleasing to see someone so passionate about teaching. Lots of admiration.

I was watching these lectures back in 2012 for biology, now I'm in med school and still love them. There really is something to be said for a gift for teaching.

I would like to thank you doctor, i am really glad of your explanation you have really made it easy to understand. God bless you

Once again, Dr. Campbell saves the day. I was trying to learn this, being taught by an instructor that merely has a Power Point with all the areas listed, and she just reads them off - fact after fact after fact..... It has no "meaning" and no context - so it doesn't stick in my head... Then I watch your videos, and it all makes perfect sense, and comes to life. I don't know if it would be rude and/or advisable to ask my teacher to please watch your videos, so that she can learn how to teach... In either event - THANK YOU FOR ALL YOU DO!! I know I am going to make a great nurse, and impact many lives, and it would have been a shame and a loss if I never fulfilled that dream, simply because I chose a school with inept professors. Please keep in mind, your videos impact my life, so that I can impact others' lives, and so it continues. You are the butterfly effect that creates tsunamis!!

Sub-dural space?

my son smashed his head in a wall made of rocks, it was soooo loud and started swelling like crazy but he got no cut nor a concussion just a tiny dent when makes facial expression. I didn't take him to the doctor because there was no sign of any damage. it was so scary and he only said mommy God made me tough
