1) The muscle cell organelle that serves as a reservoir to store calcium is the __________ __________. 2) __________ is the neurotransmitter which the human body uses in skeletal muscle neuromuscular junctions. 3) ATP’s specific function in muscle contraction is to bind to the myosin heads thereby breaking the __________ between actin and myosin. 4) In __________ muscle contraction, the tension generated in the muscle changes is not enough to exceed resistance, so the muscle length remains constant ( does not shorten).

1. True -False. If a statement is True, place a T to the left of it. If a statement is False, place an F to the left of it. Thin filaments in smooth muscles attach to Z discs. The majority of ventricular filling occurs during the period of atrial contraction known as the period of rapid filling. Closure of the atrioventricular valves occurs at the end of diastole/beginning of systole. Tetanus in skeletal muscles is the result of increasing the...

8 Number the following events of skeletal muscle contraction in the proper order, with number 1 for the first event and number 6 for the last event. A power stroke occurs as myosin moves into its relaxed position and pulls the thin filament toward the M line. Calcium ions bind to troponin, which pulls tropomyosin away from actin. ATP breaks the actin-myosin attachment, after which ATP is hydrolyzed and myosin is recocked. The myosin head binds to an actin subunit....

66) The successful transmission of a nervous impulse to a muscle fiber leads to the release of Calcium (Ca2+) from the Sarcoplasmic Reticulum. The role of Ca2+ in muscle contraction is: Bind to myosin, which cleaves ATP such that energy can be input into the myosin “heads”, allowing it to perform a power stroke needed to move actin. Ca2+ acts in a process that breaks up actin filaments, removing subunits to make them shorter and thus leading to the contraction...
