On her way to the bathroom, Laura felt the agonizing pains of her menstruation cycle in her lower abdomen area. Her nervous system is picking up on signals of pain by the sensory receptors on her uterus walls and those signals are sent down the peripheral nervous system (PNS) which act as a information highways to carry signals between the brain and spinal cord and the rest of the body. All of a sudden, Brad, Laura's crush come walking down the hall towards her. What is she gonna do with this stain on her?
OH NOOOOO! It's Brad!
Oh, hey Laura! How's it going?
In her anxious effort to escape the awkward situation she was hoping to avoid in case he saw her stain. Laura quickly tried to turn around but stepped on her own feet and fell, twisting and snapping her ankle on the way down. Laura, being the biology major that she was, knew that it was going to be at least a closed greenstick fracture on her talus or even lower fibula. Laura felt the pain all throughout her leg resonating through her femur and tibia even though it may have only affected her ankle area. She was so embarrassed-and in pain... and bleeding. How could this day get any worse? Brad walks up and rushes to Laura's side.
Oh my gosh, Laura! Are you okay? Let me help you...
As soon as she arrived to the emergency room and her suspicious of the fracture were confirmed, Laura was taken care of and given ice for the swelling of her ankle.. and some pads. Despite the series of events that plagued Laura, she was smiling through it all because Brad was by her side. She felt her cardiovascular system in action and her heart pump and race every time Brad checked up on her and asked how she was feeling or if she needed anything else. She felt the oxygenated blood running through her aortic valve and throughout her body all the way back to her pulmonary valve, contracting and passing through both the right and left atria and ventricles. She hoped Brad couldn't hear the thumping of her heart as she tried to hide the color of her cheeks from her fully-functioning
As she waited be checked out, leg intact, Laura knew her endocrine system was going crazy. As she waited she felt her adrenal gland, hypothalumus gland, and even her ovary glands secreting hormones throughout her body. She felt the adrenaline, estrogen, and even melatonin, from being tired of the day's stressful events. She hoped his adrenal glands were as active as hers were when he asked her if he could walk her to her dorm.
