concha
Quick Summary
The term "concha" can refer to different anatomical structures. In ear anatomy, the concha is the deepest depression within the auricle, leading to the external auditory canal. This part of the outer ear helps funnel sound into the ear canal.12
However, "concha" also refers to nasal conchae, which are scroll-shaped bones in the nasal cavities. These structures increase the surface area of the nasal passages, aiding in warming and humidifying inhaled air before it reaches the lungs. In humans, nasal conchae are reduced compared to other vertebrates, as our sense of smell is less critical.3
