My pre-health class for the Summer is Biology 14: Anatomy and Physiology. The class meets three times a week and has a weekly lab like other pre-health classes but this is my first time taking an evening lab session from 6:30 PM - 10:30 PM on Tuesdays. With instruction from Graduate School Teaching Assistants, each week we focus on dissecting different organs and running physiological experiments to understand the function of certain anatomical structures. 

After making sure we're following lab safety guidelines of wearing long pants and tying hair back, we put on our white lab coats, gloves and goggles. We get to work with both live and fixed animal tissues, carefully dissecting and observing specimens to see how structure and function go hand in hand in various physiological systems. These systems include the Nervous system, Sensory system, Visual system, Muscle physiology, bone systems, Endocrine system, and Cardiovascular physiology, Respiratory system Gastrointestinal system, Reproduction system and Thermoregulation. Yeah…if that sounded like a lot, it definitely is a lot of interesting stuff to memorize and learn. 

So far we've dissected sheep brain, leech spinal cord and cow heart. A big part of the class is comparison between different animal organs (like shark vs chicken eyeballs) or between human and animal organs. 

Here's a picture that my lab partner took of me holding our dissected cow heart!

Some other interesting and fun experiments we've run have been a dart throwing experiment where we tried throwing darts with and without prism goggles to observe differences in our throwing accuracy. We've also used stethoscopes and sphygmomanometers to measure each other's blood pressures after listening to music with and without lyrics! Even though an evening lab can be hard to wrap your head around, I've really liked how engaging it is and I can't wait to see what else we get to dissect and learn more about.
