POSTERIOR NARIS Meaning and Definition

  1. The term "posterior naris" refers to a specific anatomical structure in the human body, located in the posterior region of the nasal cavity. It is derived from the Latin words "posterior," meaning "behind" or "at the back," and "naris," meaning "nostril."

    The posterior naris, sometimes referred to as the posterior nasal aperture or choana, serves as the opening that connects the nasal cavity to the nasopharynx, which is the upper part of the throat situated behind the nose. The human respiratory system utilizes the posterior naris as a passageway for air to flow between the external environment and the respiratory tract. It allows for the exchange of air, thereby aiding in the process of breathing.

    Anatomically, the posterior naris is positioned in the back portion of the nasal cavity, adjacent to the nasal septum, which is the thin wall dividing the nose into two halves. Its location enables communication between the nasopharynx, where air from the posterior nasal passages and oral cavity merge, and the nasal cavity.

    The posterior naris plays a vital role in various functions. It facilitates the drainage of excess mucus produced in the nasal passages, ensuring the nasal cavity remains clean and clear. Additionally, it is an essential part of the olfactory system, as it allows aroma molecules to travel from the nasal cavity to the olfactory receptors responsible for the sense of smell.

    In summary, the posterior naris is the opening situated at the back of the nasal cavity that connects it to the nasopharynx, serving as a passage for air, mucus drainage, and olfactory cues.
