What is skeletal muscles composed of | Long, strong muscle fibers. held together by connective tissues in groups. |
Groups of connective tissues are called what | Bundles |
Bundles of connective tissue are surrounded by what | Sheaths |
Each muscle fiber contains what | myofibrils |
Each fiber contains bundles filaments responsible for what | contraction |
Filaments in each myofibril are organized into repeating untis called what | sarcommeres |
What is Peristalsis | altering wave-like contractions of both layers of muscles in a tube such as the bowels. |

Skeletal muscle perform work my pulling on the______ of the skeleton._______ serves as _____. | Bones, Bones, Levers. |
Muscles work in ______ groups, called ______ | opposing, "muscle team" |
Contraction, produce movement | isotonic |
Contracture | Flexor muscle becomes shorter resulting in perminent bent joint. |
Muscles store _______ in the form of ________ for the body. | Carbohydrates, glycogen |
What three things happen when a muscle contracts | 1. It uses stored glycogen 2. Changes glycogen to glucose as it source of energy 3. release heat |
What happens when the muscle depletes is stored glycogen | It becomes fatigued. |
