Question

Time of day 8am 10am Amount of electrical activity 5 pm Force Production 43. The above graph shows which of the following conclusions: a. There is a correlation with force production and amount of electrical activity but not with the time of day measured and amount of electrical activity. a b, There s corc aion wto n mout f e lectrical activity c·There is not a correlation with force production and amount of electrical activity but there is with the time of day and amount of electrical activity d·There is no correlation with either the force production or the time ofday with the amount ofelectrical activity 44. The galvanic skin response (GSR) transducer detects what sympathetic response? a. Heart rate b. Blood pressure c. Pulse pressure d. Sweat in sweat production? 45. Sympathetic response causes a(n) a. increase b. decrease c. no change 46. The semilunar valves closes at the beginning of a. Ventricular contraction b. Ventricular relaxation c. Atrial contraction d. Atrial re laxation

Explanation / Answer

43. Option b is the correct answer. Here position of different curves for different times are not overlapped, rather these are at different positions which indicate the relation between force production and electrical activity at different times.

44. Option d is correct. The Galvanic Skin Response (GSR) represents a change in the electrical properties of the skin. The signal can be used for capturing the sympathetic nerve responses as a parameter of the sweat gland function.

45. Option a is correct. Sympathetic stimulation increases the sweat gland production (persipiration)

46. Option b is correct. Semilunar valvs are present between ventricle and aorta and between ventricle and pulmonary trunk. Semilunar valves allow the flow of blood from ventricle to aorta and pulmonary trunk during systole (ventricular contraction) and thus it closes at the begining of ventricular relaxation.
