"Nervus dorsalis panis" is a Latin term that describes a nerve that runs along the back of a bread loaf. The correct spelling is "nervus dorsalis panis," which is pronounced /ˈnɛrvəs dɔrˈsaːlis ˈpanɪs/ in IPA phonetic transcription. The term is rarely used in modern language and is often cited as an example of humorous or nonsensical Latin words. However, it remains a popular curiosity among language enthusiasts and scholars alike.
