The term "agger nasi" refers to a bony ridge located within the nasal cavity. Its spelling is unique due to the use of Latin words. The "a" in "agger" is pronounced as a short "a" sound, while the "e" in "nasi" is pronounced as a long "a" sound. The IPA phonetic transcription for this term is /ˈæɡər ˈneɪsi/, with emphasis on the first syllable of both words.

Agger nasi is a term derived from Latin which refers to a specific anatomical structure found in the human nose. It is a protrusion or bony ridge located in the lower region of the nasal cavity, specifically in the area between the nasal septum and the nasal floor.
The agger nasi, also known as the nasal agger or nasal ridge, is formed by a thickening of the nasal bone and is primarily composed of cartilage. It runs horizontally across the nose, extending from the frontmost portion of the nasal cavity toward its back, adjacent to the maxillary sinus. The agger nasi serves as a landmark within the nasal anatomy and is relevant in the fields of rhinology, otolaryngology, and related medical specialties.
This structure has various functions within the nasal cavity. It is believed to contribute to airflow dynamics by helping to guide and direct the passage of air through the nose. Additionally, the agger nasi may play a role in the support and stability of the nasal framework.
Overall, the agger nasi is a significant component of the nasal anatomy, influencing nasal functionality and contributing to the overall structural integrity of the nose. Its detailed understanding is crucial in medical contexts such as nasal surgery and the diagnosis and treatment of nasal disorders.

"Agger nasi" is a Latin term that translates to "nasal mound" in English.
The word "agger" comes from the Latin verb "aggerere", which means "to heap up" or "to raise". This word is derived from the prefix "ad-" meaning "to" and the verb "gerere" meaning "to carry" or "to bear". In ancient Rome, an "agger" referred to an embankment or a rampart built for defense purposes. Over time, the term expanded to be used in various contexts, including in anatomy.
The term "nasi" is the genitive form of "nasus", the Latin word for "nose".
When combined, "agger nasi" describes a raised area or a mound on the nose.
