What's the difference between auricle and pinna?

Auricle


Definition:

  • (n.) The external ear, or that part of the ear which is prominent from the head.
  • (n.) The chamber, or one of the two chambers, of the heart, by which the blood is received and transmitted to the ventricle or ventricles; -- so called from its resemblance to the auricle or external ear of some quadrupeds. See Heart.
  • (n.) An angular or ear-shaped lobe.
