AVS 333 - Anatomy and Physiology Laboratory
Course Information

Professor: Dr. Katherine Petersson
Semester: Fall
Credits: 1
Prerequisites: Completion or concurrent enrollment in AVS 331 is required.

Catalog Description: The fundamental anatomy of domestic animals is examined. Demonstrations of physiological principles are performed. Laboratory techniques for screening physiological function in vivo and in vitro are covered.

Course Goals & Outcomes

By the end of this laboratory students should be able to:

  • Identify by name, bones of the skeletal system
  • Identify by name, the primary components of each organ system
  • Articulate how the primary organ systems function
  • Articulate how different organ systems work together to maintain homeostasis

Dr. Petersson's research interests are focused around animal nutrition and biochemistry. Much of her research has explored the use of vitamin E by the body. Previous projects have looked at the effect of exercise on the vitamin E requirement of the horse. She also has looked at effect of vitamin E supplementation on the immune function and response to vaccination in horses. Currently, Dr. Petersson is doing similar research on sheep. In addition to conduction research, Dr. Petersson is the advisor to several graduate students and teaches courses in Animal Anatomy Physiology and Nutrition.
