calcaneal 中文解釋 wordnet sense Collocation Usage Collins Definition
  1. relating to the heel bone or heel
  2. (calcaneus) heelbone: the largest tarsal bone; forms the human heel
  3. (Calcaneus) This word derives its name from the Latin word calx = chalk or limestone, perhaps from a fancied resemblance to that substance. The bone is also known as the os calcis or chalk bone. Calcium, a key element in limestone, is another word with the same  etymology.
