Defense Mechanism

Circumstances influence and compel people to behave in a certain way. One such behavior is a defense mechanism. It is employed by people to escape from unpleasant circumstances, thoughts and actions. Defense mechanisms are, thus, psychological strategies that help to avert and avoid unwanted feelings such as guilt or shame and situations such as threat and danger.

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.
Watch this video (http://openstaxcollege.org/l/micromacro) to learn more about macro- and microstructures of skeletal muscles. (a) What are the names of the junction points between sarcomeres? (b) What are the names of the subunits within the myofibrils that run the length of skeletal muscle fibers? (c) What is the â€œdouble strand of pearlsâ€� described in the video? (d) What gives a skeletal muscle fiber its striated appearance?
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.
Concerning the cross-bridge (CB) power stroke, it is true that: O a. All of these O b. In concentric contractions, the CB power stroke pulls the actin filament toward the center of the sarcomere, causing sarcomere shortening O C. In isometric contractions, the CB power stroke pulls the actin filament straight down, preventing shortening or lengthening O d. In eccentric contractions, the CB power stroke pushes the actin filament away from the center of the sarcomere, causing sarcomere lengthening TOSHIBA
According to the sliding filament theory: O a. The tension increases linearly as actin-myosin overlap increases O b. All of these O c. The interference between actin filaments reduces ability of crossbridges to develop tension d.

Now in your own words, EXPLAIN (1) howa neural impulse is transferred to a muscle cell this is the process of “muscle excitation"), and (2) how the electrical impulse travels into he T-tubules and causes calcium to be released from the sarcoplasmic retículum (this is the process of “excitation-contraction coupling"): OMADidoinos reticulum 5. se mo S1e hosph erah anism
