Re: What is the weakest Bone and weakest Muscle in the Human body?

Hello,

It's difficult to say which muscle and bone is the "weakest" because 
that takes into account the composition of the bone/muscle as well as the 
shape and size. In terms of size, however, the "smallest" bone in the 
body that I could think of is the stapes, which is one of the three 
auditory ossicles that form a connected chain in the human middle ear 
(the other two are called malleus and incus - together they transmit 
vibration from the ear drum to the inner ear). The smallest voluntary 
(striated) muscle of the body is the stapedius, which is a tiny muscle 
that pulls on the stapes to stabilize it and prevent it from excessive 
movement. It contracts to protect our hearing when we are in a very noisy 
environment.

I hope this would help:-)
