Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.

Question

If acetylcholine re-uptake is blocked in the synaptic cleft, then what
happens in the muscle cell?
The cell won't be able to contract.
Tetanus.
Calcium levels in the sarcoplasmic reticulum go up.
Calcium levels in the sarcoplasm go down.

Skeletal muscle contraction requires _________. a. calcium ions b. ATP c. arrival of a nerve impulse d. all of the above
Figure 38.37 Which of the following statements about muscle contraction is true? The power stroke occurs when ATP is hydrolyzed to ADP and phosphate. The power stroke occurs when ADP and phosphate dissociate from the myosin head. The power stroke occurs when ADP and phosphate dissociate from the actin active site. The power stroke occurs when Ca2+ binds the calcium head.
Nerve impulses first stimulate a skeletal muscle fiber at _______. a. T tubules b. sarcomeres c. neuromuscular junctions d. actin binding sites
After death, a person no longer makes ATP, so calcium stored in the sarcoplasmic reticulum diffuses down its concentration gradient into the muscle cytoplasm. This result is rigor mortis----an unbreakable state of muscle contraction that stiffens the body for a few days until muscles begin to decay. Explain why this contraction occurs.
