Abstract

A farmer becomes concerned after discovering a number of dead animals on his small farm, including some ducks, several deer, and a coyote, all within a single week. Fearing that someone might be poisoning his land, he calls in a veterinary pathologist to investigate. The case is designed to teach students in an upper-division comparative anatomy and physiology class about the central nervous system.


Objectives

  • Learn that all vertebrate nervous systems are essentially similar.
  • Describe how an action potential is initiated and propagated.
  • Describe how neurons communicate with each other and with other cells.
  • Describe the neuro-muscular junction.
  • Apply knowledge of nervous system physiology to understanding the mechanisms of action of two neurotoxins.
