I would like to welcome you to the 21st century classroom of human anatomy and physiology. This warm-up or bell ringer on the "overview of the muscle cell". You will find vocabulary terms being used to review and test your basic knowledge. When "fill-in" questions appear in the test, please enter all answers in lower case letters. I wish you the best of luck and make high marks on this physiology of the muscular system.
