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:-) Joshua Chai Student Doctor School of Clinical Medicine University of Cambridge, UK
