Question

True/false questions: if the answer is true black out the letter (A) and if the answer is false or partially false black out the letter (B). Inhibition of Acetylcholineesterase will initiate flaccid paralysis since and it breaks down Acetylcholine to acetate and choline The activity of myosin ATPase is the same in both slow-twitch and fast-twitch muscle fibers Fast twitch fibers have larger CP stores than slow-twitch fibers Muscle fiber types may be changed completely and irreversibly only by cross-innervation Alpha motoneurons are located in the brain cortex 74. Low capillary density of FG muscle fibers is compensated by the high myoglobin concentration of those fibers. SO fibers have very well developed sarcoplasmic reticular system. The higher is the sarcoplasmic calcium concentration the higher is developed force. During muscular contractions the rate of change in tension is direct is the rate of the calcium concentration. In a relaxing muscle fiber the higher is t

Explanation / Answer

67 The relationship between cardiac output and metabolic rate is

answer : DIRECT linear

In general, heart rate increases in direct proportion to the metabolic rate during exercise. At any level of oxygen consumption, heart rate and blood pressure are lower during leg work when compared with arm work. ... An increase in cardiac output will decrease blood pressure when peripheral resistance is constant.

68. option B----1 and 2 only

upper limb RE produces diverse cardiovascular reactions contrasted with lower appendage work out. It is settled that upper appendage practice prompts to higher circulatory strain (BP) and heart rate (HR) than lower appendage practice because of a higher work part and hoisted fringe resistance brought on by lessened dynamic muscle mass.
