Welcome!

This is the first post to this blog dedicated to students of Dr. Williams' Bio 9G course. I want you to see some of the cool effects of physiology out in the real world. And if I use a blog, you have the opportunity to comment back and share how you feel about it. Here's a quote that nicely shows how I feel about physiology:

"The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful." Jules Henri Poincaré (1854-1912).

This picture shows the structure of a heart muscle cell. Cool, isn't it? It was photographed by Denis Kunkel, who has lots of great medical photos you can look at here.
