BIOL243 Vertebrate
Anatomy
(3,3) 4
A detailed study of the origin,
phylogeny and anatomy of the
vertebrates. Laboratories
emphasize the thorough
dissection of representatives
of at least three classes of
vertebrates. Prerequisite:
BIOL132 and sophomore
standing.
The study of vertebrate anatomy provides insights into the evolution, ecology, and physiology of
these animals. Consequently, there are different ways to approach this discipline. You can view
each animal as a simple collection of parts to be found, identified and memorized. Alternatively,
you can study the anatomy of these animals to provide a foundation for elucidating their ecological
and physiological abilities and limits. Finally, you can compare similarities and differences
between species to shed light on evolutionary processes.
I combine these approaches in this course. In lecture I emphasize the phylogeny of major
physiological systems. An overview of each system is presented followed by a discussion of how
the elements of the system have been modified via natural selection. These discussions focus on
selective pressures that may have impacted the evolution of the various vertebrate taxa.
In the lab, we focus on the more technical aspects of finding and recognizing components of the
skeletal, muscular, digestive, reproductive, respiratory, and circulatory systems. The comparative
approach of lecture is maintained by examining each system in different specimens concurrently.
Although this course does present a lot of information and terminology, this is not a conceptually
difficult discipline. In my experience, those students who put quality time into their studies will not
only be successful, but will enjoy the learning process as well.
