Question
6. Which of the 1y An actian folowlarity between cardiac and smooth muscle cellst ial always precedes a contraction. contraction The majority of Ca that activates contraction comes from the extracellular fluid. Q Action potentials are genera ted by slow waves. D) An extensive system of T tubules is present. E Ca release and contraction strengths are 7. to an isoosmotic saline solution containing cells, what If a small amount of urea were added would be the result? A) The cells would shrink and remain that way B) The cells would first shrink and C) The cells would swell and remain that way an volume then rapidly be restored to normal cells would first swell and then rapidly be restored to normal volume. E) Urea would have no effect, not even transiently 8. The specificity of an antibody is determined by A) The fixed segment (or constant fragment) B) The size of the antibody C) The variable region D) The antigenic determinants E) The antibody dlass influences bone growth by stimulating the secretion offrom the liver and other tissues A) insulin B) calcium C) Insulin-like growth factor D) Calcitonin E) Vitamin D 10. In an experimental situation, a virus is injected into a rabbit and the rabbit is allowed to make antibodies for the viral antigen. These antibodies are then removed from the rabbit plasma and injected into a human to help combat the same viral disease. This is an example of A) Innate immunity B) Passive immunity C) Active immunity D) Autoimmunity E) Anaphylaxis systolic blood pressure of 120 mm Hg, and a pulse pressure of 40 mmHg her If a person has a mean arterial pressure would be A) 100 mmHg B) 80 mm Hg C) 93 mm Hg 11. D) E) 200 mm Hg 40 mm HgExplanation / Answer
6)ans. E ca+2 release and contraction strengths are graded
7)ans.B first cells shrink late become normal
8)ans C variable region
9)ans C insulin like growth factor
10)ans B. Passive immunity
11) ans C. 93mmhg
Explanation:MAP=DIASTOLIC BP+1/3rd PP
80+1/3*40
93mmhg
