| Question | Answer |
|---|---|
| skeletal muscle surrounded by a connective tissue sheath | epimysium |
| connective tissue located outside the epimysium; surrounds and separates muscles | fascia |
| ability of skeletal muscle to shorten with force | contractility |
| capacity of skeletal muscle to respond to a stimulus | excitability |
| ability to be stretched | extensibility |
| ability to recoil to their original resting length after they have been stretched | elasticity |
| loose connective tissue that surrounds the fascicles | perimysium |
| single muscle cells that make up the fasciculi | fibers |
| connective tissue sheath that surrounds a fiber | endomysium |
| threadlike structure that extends from one end of the fiber to the other | myofibrils |
| thin protein fiber that resembles two minute strands of pearls twisted together | actin myofilaments |
| thick protein fiber that resembles bundles of minute golf clubs | myosin myofilaments |
| highly ordered units of actin and myosin myofilaments | sarcomeres |
| area that a sarcomere extends from | Z line |
| area on each side of the Z line that consists of actin | I band |
| area in the center of a sarcomere that consists of myosin | H zone |
| dark staining band where myosin myofilaments are anchored in the center | M line |
