Skeletal muscle moves because we want it to. It is controlled voluntarily (consciously). There is 2 types of contraction Isometric: As the muscle contracts‚ it remains the same length whilst the tension increases in an attempt to overcome the opposing force. Example: Holding a glass of water still in front of you. Isotonic: As the muscle contracts its length changes whilst the tension remains constant or develops to overcome the opposing force. Example: Lifting a glass of water to your mount and

Advance Preparation—ATP Muscle Kit 1. Order the ATP muscle kits (Carolina) to be delivered no more than seven days before the lab. One kit provides generously for eight students. Extra vials of the chemical solutions can be ordered separately (Carolina) and will reduce waiting time. Just before the lab begins‚ cut the muscle bundles into 2-centimeter lengths and place in a petri dish in the accompanying glycerol. 64 Exercise 11 R E V I E W S H E E T NAME ____________________________________

Muscle fatigue occurs when a muscle has a diminished ability to continue to produce force‚ usually occurring due to extensive use of those muscles‚ such as when performing extraneous activity. On a molecular level‚ there are a number of things that happen that prevent the muscle from performing more action‚ ultimately to prevent any damage from being afflicted on the muscles cells. One particular effect that most people are likely familiar
