auricle

Definition of auricle

aur-i--cle - portion of external ear not contained within the head (little ear) In human anatomy, the auricle serves two primary functions depending on its location:

• Otology: It is the visible, cartilaginous part of the outer ear that captures and funnels sound waves into the external auditory canal. It consists of several distinct regions including the helix, antihelix, tragus, and lobule.
• Cardiology: It refers to the atrial appendage, a small, wrinkled, muscular pouch extending from the right and left atria of the heart. These structures act as reservoirs to increase atrial volume and are clinically significant in conditions like atrial fibrillation, where blood may pool and form clots.
