20. Tension is the pull or active force on a muscle tendon.  It results from? a.    sarcomeres making up muscle fibers becoming shorter during contractionb.    thick and thin filaments becoming longer during contractionc.    overcoming resistance of gravity and prevention of bone movementd.    tendons becoming shorter during contractione.    shortening of the overall muscle fiber thus pulling on tendons attached to bones

17. Botulism toxin is a weapon of mass destruction that prevents release of acetylcholine at the        synaptic terminal  MNJ.  How does this toxin affect muscular activity? a.    causes spastic paralysis due to continuous stimulation of muscleb.    it has no effect on muscle contractionc.    causes spastic paralysis due to continuous relaxation of muscled.    causes flaccid paralysis due to inability of muscle to contracte.    causes an continuous release of ACH at the MNJ  

28.    Smooth muscle, cardiac muscle, visceral organs & glands are effectors or targets of the? a.    automatic nervous systemb.    somatic nervous systemc.    autonomic nervous systemd.    sensory or afferent division of the PNSe.    CNS

19. Duration of muscle contraction depends on all the following, EXCEPT?       Which item below does not occur in muscle contraction? a.    stimulation by an action potential (“nerve impulse”) at MNJ by ACHb.    the amount  of calcium released from the sarcoplasmic reticulumc.    availability of ATP to break cross-bridgesd.    availability of cholinesterase to neutralize ACH and stop the process at the MNJe.    the amount of sodium released from the sarcoplasmic reticulum

New ideas and breakthrough solutions occur when there is just enough tension and just the right clash of ideas, which is called:

A headline is a leading sentence which can be found at the top or bottom of the ad.

A shoe company would like men to at least buy their boots once and see how they like it. Which of the following is more likely to be the company’s objective?

The concept of message strategy refers to methods, not objectives— how you want to plan it not what you want to do.

A retailer marks down a customary price (i.e., the price consumers are accustomed to paying) of a popular item (e.g a bread, washing liquid or some veggies)  in an attempt to attract more customers.
