CHOANA Meaning and Definition

1. A choana, in biological terms, refers to a specific anatomical structure found in certain species, typically related to respiration and sensory perception. It is commonly observed in various organisms, including humans, birds, reptiles, and several types of amphibians.

   Specifically, in humans, the term "choana" refers to the posterior nasal aperture, which is the opening at the back of the nasal cavity that leads into the nasopharynx. This aperture serves as a passageway for the exchange of air between the nasal cavity and the throat. Additionally, choanae play a crucial role in the olfactory system, allowing smells and odors to be detected by the sensory cells in the nasal cavity.

   In non-human vertebrates, the term "choana" is often used to describe specific structures related to respiration. For example, in birds and reptiles, choanae are external nasal openings located on the roof of the mouth, behind the hard and soft palate. They enable these animals to breathe while their mouths are closed during feeding, swimming, or diving. In frogs and some other amphibians, choanae refer to the internal nasal openings that connect the nasal cavity with the oral cavity, allowing them to breathe effectively when submerged in water.

   Ultimately, the term "choana" pertains to the respective structures associated with respiratory function and sensory perception in various organisms, facilitating essential physiological processes.

2. An infundibulum; specifically posterior naris, the opening into the nasopharynx of the nasal fossa on either side.
