I'm beginning my undergrad education this fall. I took AP Calculus in my junior year of high school. My school didn't offer any math after AP Calc and so I haven't done any calc for over a year. Does anyone know any good websites where I can go to review calculus concepts before I start college?
I know that smooth and cardiac muscle cells (myofibers) are connected to each other by gap junctions.
How are skeletal muscle cells connected to each other (to transmit the AP)?
Thanks, any responses appreciated
