W. Crone (303 FTZ, 629-7439, cronewil@hvcc.edu, http://www.hvcc.edu/academ/faculty/crone/index.html)

WEEK 6: THURSDAY, FEBRUARY 2/24/00 (NOTE NEW DATE), 7:50 - 9:50 AM. Bring #2 pencils.

(If HVCC is closed that day, the test will be given on Thursday 3/2/00 of week 7)

This first lecture exam will cover the lecture/text material for weeks 1-5 (to complete through the cardiovascular system, or as much of it as we're going to get to in Physiology). It will be based on lectures discussed/touched on in lecture, although your understanding should be enhanced by your readings in the texts. Note that you will have two hours--given that Microbiology 03024 follows at 10 AM, you won't have"open-ended" time to finish the test!


30 multiple choice questions

worth two points each

60 points possible

6 short essay questions

worth fifteen points each

90 points possible

total possible for test

150 points possible

The essays will target situations that are worth additional study, as indicated in the course outline. I've listed them again below. Rest assured that each will be either in an essay and/or at least one multiple choice question. Be particularly prepared to address"case studies" from Michael and Rovick, van Wysberghe and Cooley, and Cormack that are applicable but not covered in the recitation sections (as you probably noticed during the Anatomy tests!).

Week 1: Introduction, Review of Cell Biology, Review of Hematology Stem Lines

Week 2: Membrane Function and Membrane Potentials, Muscle Function

Week 3: Introduction to Nerves, Autonomic Nervous System

Week 3: Introduction to Nerves, Autonomic Nervous System (continued)

Weeks 4 and 5: Cardiovascular System


Even more so than in Anatomy 03048, I intend to have the multiple choice questions to be thought-provoking and"problem-solving." If you know the material at the level of we're discussing it during lecture and recitation, you should be able to answer them. Examples from a previous year's test follow, with the answers at the bottom of the next page.

1. Which statement about membrane phospholipids is true?

A. A phospholipid contains cholesterol.

B. Phospholipids move rapidly in the plane of the bilayer.

C. Specific phospholipids are always present in equal proportions in the two halves of the bilayer.

D. Phospholipids form ion channels through the membrane.


2. The osmotic flow of water across a membrane will decrease if there is a decrease in:

A. the permeability of the membrane to the particles in solution.

B. the particle's concentration difference across the membrane.

C. both

D. neither


3. In a normal person, which chamber/region should have the lowest overall pressure during the cardiac cycle?

A. left ventricle

B. right ventricle

C. left atrium

D. right atrium

E. pulmonary artery


4. An EKG reveals no P waves in any lead. This would indicate that impulses from which one of the following structures are being blocked?

A. sinoatrial (SA) node

B. bundle of His

C. Purkinje fibers

D. left bundle branch

E. ventricular muscle


5. The following values were recorded in an experiment:

capillary hydrostatic pressure: 25 mm Hg

capillary oncotic pressure: 30 mm Hg

tissue hydrostatic pressure: 3 mm Hg

tissue oncotic pressure: 10 mm Hg

The net forces favor:

A. filtration by 2 mm Hg

B. reabsorption by 2 mm Hg

C. filtration by 12 mm Hg

D. reabsorption by 12 mm Hg

E. filtration by 42 mm Hg


6. An adult male is seen in the clinic with the following findings:

cardiac output: 5 L/min

blood pressure: 200/120

heart rate: 80 bpm

plasma catecholamines: normal

plasma angiotensin: normal

blood volume: 5 L

total peripheral resistance: increased

From the above data, one can conlude that the patient is:

A. hypertensive due to excessive cardiac activity

B. suffering from essential hypertension (i.e., of unknown origin)

C. in hypotension of renal origin

D. hypertensive as a result of excessive adrenomedullary secretion

E. suffering from hypertension of neural origin



answers: 1-B, 2-B, 3-D, 4-A, 5-A, 6-B
