Multiple Choice

1. You have a lamb that has just suffered a laceration and is bleeding. From a physiological standpoint, what needs to happen to stop the bleeding?

a. Apotransferrin and Transferrin protein are activated and platelets form the plug

b. Constriction of the injured vessel, Formation of platelet plug to occlude the opening and clot formation

c. Constriction of the injured vessel recruitment of eosinophils, basophils and neutrophils and clot formation

d. Formation of platelet plug, inflammation and increase in the Erythrocyte cells

2. Cats have better nocturnal vision because:

a. The depth perception is greater due to the medial location of the eyes

b. The convex lens and the pupil have a greater range of dilation

c. Cats have a larger cornea area compared to dogs

d. Cats have a greater area on the tapetum lucidum

for each of the following pair of endocrine disorders, list the gland(s) and hormone(s) involved and then indicate one difference between the disorders
a.Diabetes mullitus and diabetes insipidus

b. cushing syndrome and Addison diease

c. Hypothyroidism and hyperthyroidism

37. High blood pressure could be rectified by all of the following except

A. An increase in ADH

B. A decrease in aldosterone

C. ACE inhibitors

D. All of the answer choices are correct

14. Ectopic pregnancy, where implantation of the embryo occurs in the fallopian tube rather than the uterus is possible because

A. Fertilization may have occurred in the ovary with subsequent implantation in the fallopian tube

B. Fertilization occur in the fallopian tubes and the embryo may fail to migrate to the uterus

C. The fimbriae may hold the embryo in the fallopian tubes rather than pushing it toward the uterus

D. Though fertilization takes place in the uterus, implantation does not occur immediately and thus the embryo could migrate back up into the fallopian tubes

There can be more than 1 right answer. Is it B and C both? I know it happens by diffusion and it says passive transport. But proteins are required too? or does it just work with diffusion.

17. Reabsorption of H2O in the medullary collecting ducts is by

A. active transport

B. simple diffusion

C. facilitated diffusion

D. endocytosis

87. True or False: Blood agglutination and blood clotting are different names for the same process.

90. True or False: In terms of affecting hormone action, synergism and permissiveness mean the same thing.

93. True or False: The thymus plays an important role in the development of T cells.

Name and describe the roles of the substances produced by the exocrine portion of the pancreas.

What is a descending tract? Identify each descending pathway discussed in class. Identify the function, where they are located within the spinal cord, where they terminate, the structures involved, and whether they decussate or not. If they do decussate, identify where that process occurs and why it is important for that pathway to decussate.
