How is a tendon different from a ligament? a. a tendon joins a bone to a bone; a ligament joins a muscle to a bone. b. a tendon joins a muscle to a bone; a ligament joins a bone to a bone. c. a tendon covers a bone; a ligament supplies nutrients to a bone. d. a tendon supplies nutrients to a bone; a ligament covers a bone.

B is correct. A tendon will join a muscle to a bone, and a ligament joins a bone to another bone. I think of it this way, partly influenced by my biology teacher:

- The achilles tendon, at the back of your foot, clearly joins foot to calf muscle
- The word ligament comes from 'deligare' in Latin, which roughly means to tie           together. A ligament 'ties' two bones together

I hope this helps

That would be a working theory.
