****502 Students: Read this paragraph ****
If you are a 502 student using this guide, this is based on Dr. Rust’s lectures in Physiol 201. Topics may have been covered in more detail in 502 or the coverage or emphasis may have been different since many topics in 502 were taught by other professors- so use your notes and slides along with this guide.
THIS PACKET IS NOT SIGNIFICANTLY MODIFIED FROM SEMESTER TO SEMESTER.
THE MATERIAL HERE MAY BE SOMEWHAT DIFFERENT THAN THE COVERAGE IN LECTURE THIS SEMESTER. SO- USE YOUR NOTES AND SLIDES. • Topics that WERE covered in lecture, but are not here, ARE REQUIRED MATERIAL for the Final Exam. This is not meant to replace your slides/notes, but to give you a guide and a place to start. • Topics that were NOT covered in lecture, but that are covered here (or with differing amount of detail here than in lecture), ARE NOT REQUIRED material for the Final Exam. • Again- this is not meant to replace your slides/notes…
Topics I am aware are missing (there may be others): Reproductive Physiology
HOMEOSTASIS
Homeostasis is the maintenance of relatively stable conditions of the internal environment. The “internal environment” is the extracellular fluid- the fluid outside the cells. The extracellular fluid is comprised of the plasma and the interstitial fluid.
Homeostatic reflex arcs are stimulus response sequences that involve negative feedback and are designed to respond to a change in a variable by bringing the variable back toward normal. Examples of variable regulated by homeostatic reflex arcs are: Body Temperature Blood pressure Arterial PO2 and PCO2 Arterial pH Plasma Glucose Plasma Na+, K+, Ca2+ And many more.
