In the auditory system, the columella contributes to hearing in amphibians, reptiles and birds. The columella form thin, bony structures in the interior of the skull and serve the purpose of transmitting sounds from the eardrum. It is an evolutionary homolog of the stapes, one of the auditory ossicles in mammals. In many species, the extracolumella is a cartilaginous structure that grows in association with the columella. During development, the columella is derived from the dorsal end of the hyoid arch.

- Columela auris es el bastoncillo de hueso o cartílago que forma el huesecillo único del oído medio de anfibios, aves y reptiles. Es homólogo de la hiomandíbula de los peces y del estribo de los mamíferos. El nombre en latín, columella auris, significa «columna del oído». (es)
- 耳柱骨(英語:columella)是爬蟲類、兩生類與鳥類的聽小骨,可將聲波從鼓膜傳到內耳,其內端較粗,緊貼內耳的卵圓窗;外端較粗,連接在鼓膜中央。其功能相當於哺乳類中耳的鐙骨。 (zh)

| - En l'aparell auditiu la columel·la contribueix a l'oïda en els amfibis, rèptils i ocells. La columel·la forma estructures primes i òssies a l'interior del crani que transmeten els sons captats al timpà. És un homòleg evolutiu de l'estrep, un dels ossicles auditius dels mamífers. En moltes espècies l'extracolumel·la és una estructura cartilaginosa que creix associada amb la columel·la. Durant el desenvolupament, la columel·la deriva de l'extrem dorsal de l'. (ca)
