Hey gang,

As promised, here's the links to the muscle websites I used in class today:

1.  A nice overall review of muscles can be found here.

2.  This site covers the stimulus and the way calcium is used on the molecular level.

3.  This is a nice animation for how sarcomeres (overlapping muscle proteins) contract.  It is a bit annoying though, because it keeps asking for you to set-up a trial membership
