concha meaning
Nasal concha. In anatomy, a nasal concha (/ËkÉnkÉ/), plural conchae (/ËkÉnki/), also called a turbinate or turbinal, is a long, narrow, curled shelf of bone that protrudes into the breathing passage of the nose in humans and various animals. The conchae are shaped like an elongated seashell, which gave them their name (Latin concha from Greek ÎºÏÎ³ÏÎ·). A turbinate bone is any of the scrolled spongy bones of the nasal passages in vertebrates.
