*Dorsal nasal meatus: Between the dorsal nasal meatus and the dorsal concha. It leads directly to the caudal nasal cavity.
*Dorsal nasal meatus: Between the dorsal nasal meatus and the dorsal concha. It leads directly to the caudal nasal cavity.
*Middle nasal meatus: Between the dorsal and ventral nasal conchae, communicates with paranasal sinuses and leads into the caudal nasal cavity.
*Middle nasal meatus: Between the dorsal and ventral nasal conchae, communicates with paranasal sinuses and leads into the caudal nasal cavity.
*Ventral nasal meatus: Between the floor of the nasal cavity and the ventral nasal concha. This is the largest meatus and is the main passage of airflow to the nasal cavity via the nasopharynx.
*Ventral nasal meatus: Between the floor of the nasal cavity and the ventral nasal concha. This is the largest meatus and is the main passage of airflow to the nasal cavity via the nasopharynx. Nasogastric tubes, passed through the nasal cavity, pharynx and oesophagus to the stomach, must be passed through this meatus to avoid the highly vascularised ethmoturbinates.
*Common nasal meatus: Either side of the nasal septum, communicates with all other meatus.
*Common nasal meatus: Either side of the nasal septum, communicates with all other meatus.
