Welcome cell signaling and the endocrine system

Today we read the article: Brain Image Study: Fructose May Spur Overeating as well as the abstracts of the studies that were mentioned in the article.  We used our discussion of the studies to transition from the nervous system to the endocrine system and cell signaling.

Today in class you received a copy of the objectives for the next two weeks and this weekend I'll post the online version with hyperlinks on the blog.

Your homework tonight is to read Module 22, with the following substitutions: 

When you get to the sentence "One important second messenger, cyclic adenosine monophosphate or cAMP, derives from ATP (Figures 2a and 2b)" stop reading and instead   watch this animation of how cAMP works. It's much less confusing than the explanation provided in the book. 

Resume reading at the section "How can a small signal lead to a big response?"  Actually take the time to click through Fig. 4.  

Do not panic when you see Fig. 5. 

And because at some point you will want to take a study break, here's the link to the BBC interactive graphic where you can see which Olympic athlete you are.
