Pinna nasi is a Latin term that refers to the external part of the nostril. Phonetically, this word is spelled as /ˈpɪnə ˈnɑːsi/, where the first syllable "pin" is pronounced as [pɪn], followed by the second syllable "na" pronounced as [nə], and the third syllable "nasi" is pronounced as [ˈnɑːsi]. The spelling clearly indicates the pronunciation of each syllable, making it easier for people to understand and use the term accurately. The correct spelling and pronunciation of medical terms are essential to avoid confusion and ensure effective communication in the healthcare industry.
Pinna nasi refers to the external cartilaginous structure located at the lower part of the nose, forming its fleshy wings or sides. Often simply referred to as the nostrils or nasal wings, pinna nasi are easily visible on the front of the nose and are an essential component of the respiratory system. These fleshy projections lead into the nasal cavity, providing an entrance and exit for air as one breathes.
The pinna nasi are responsible for facilitating the inhalation and exhalation of air during respiration. They play a vital role in breathing as they help to filter and warm the air before it enters the body. These structures assist in trapping dust, allergens, and other foreign particles present in the air, preventing them from entering the respiratory system and potentially causing harm. Additionally, the pinna nasi contain mucous membranes, which are responsible for producing mucus to moisten the air that is being inhaled, aiding in its filtration and purification.
Apart from their functional significance in respiration, the pinna nasi also contribute to the aesthetical appearance of the nose. Their shape and size can vary among individuals, and they are often considered a defining feature of the nose and overall facial structure.

The word "pinna nasi" is derived from Latin.
- "Pinna" comes from the Latin word "penna", meaning "feather" or "wing". In this context, it refers to the outer part or flap-like structure of the nose, which resembles a wing or feather.
- "Nasi" comes from the Latin word "nasus", meaning "nose".
Thus, "pinna nasi" can be translated as "wing of the nose" or "flap of the nose" in English. The term is commonly used in anatomy to refer to the structure around the nostrils or the external part of the nose.
