Hi all
A friend asked me to help him develop a Lab instruction for the Physiology of the frog jumping muscle (gastrocnemius).
Anyone have an experience with it, or could give me some ideas on what should I emphasize?
I have several ideas, but need some more assistance.

Take a look at this website

http://en.wikipedia.org/wiki/Gastrocnemius

some of the concepts that would be interesting to cover are the identification of threshold and maximum stimuli, and the diffferent parts of the twitch response (latent period, contraction, relaxation). you can also look at wave response, muscle fatigue, tetanus etc. but students will need to get a handle on stimuli and the twitch response first to understand these!

let me know if you more detailed info about how to linclude these concepts in a lab exercise.
