How are muscles attached to bones?
actually muscles are attached to bones by tendons
More tendons are attached because tendons are what attatch bones to bone. Yes, muscles do also have to be attached but bones need to be attactched for muscles to even be in the body. Without your bones attached you would just be a giant blob just like if you wouldn't have cartilage to keep bones from rubbing down to nothing. Cartilage helps you move more smoothly.
