 Bone-muscle lever types

Hello All;

I have been given a challange by my anatomy professor, and am
looking for help.

She has challanged us to find any more type 1 or type 2 lever
types in the body than the ones that she has given us.

For type one, there is only one, which is the alanto-occipital
jt. - raising the head off the chest.

For type two, she gave us two examples, standing on your toes,
and the JM join movement.

Does anyone know of any other joints in the body that would fit
in either of the above catagories?

Posting or mail would be great. I check these newsgroups
everyday, and sound is very well connected for email

Thanks for you time and effort

        This is false -- the atlanto-occipital joint is not the only
1st class lever in the body.  Your mission, should you choose to accept
it, is to find others and point them out to your professor. :-)

        Seriously though, given the definitions of 1st, 2nd and 3rd
class levers together with the knowledge you have from anatomy class
wouldn't it be more interesting and worthwhile to go sleuthing on your
own rather than asking the net?

Yes, I agree. My question was this. I am looking for type 1 and type 2
joints in the body. I am not looking for any type 3 joints in the body
which are the VAST majority.

Thanks for the thought though
