The frontonasal duct may or may not drain into the ethmoidal infundibulum - this is determined by the place of attachment of the uncinate process of the ethmoid bone: if the uncinate process is attached to the lateral nasal wall, the frontonasal duct will open directly into the middle nasal meatus; if otherwise, it will drain into the infundibulum.
54378. Anatomical terminology. [ edit on Wikidata] The nasal cavity is a large, air-filled space above and behind the nose in the middle of the face. The nasal septum divides the cavity into two cavities, [ 1 ] also known as fossae. [ 2 ] Each cavity is the continuation of one of the two nostrils. The nasal cavity is the uppermost part of the ...
Below the bulla ethmoidalis and hidden by the uncinate process of the ethmoid is the opening of the maxillary sinus (ostium maxillare); an accessory opening is frequently present above the posterior part of the inferior nasal concha. The inferior meatus is the largest of the three. It lies below the inferior concha and above the nasal cavity.
Ethmoid sinus. Coronal section of nasal cavities. The ethmoid sinuses or ethmoid air cells of the ethmoid bone are one of the four paired paranasal sinuses. [1] Unlike the other three pairs of paranasal sinuses which consist of one or two large cavities, the ethmoidal sinuses entail a number of small air-filled cavities ("air cells"). [2]
The inferior nasal concha (inferior turbinated bone or inferior turbinal/turbinate) is one of the three paired nasal conchae in the nose. It extends horizontally along the lateral wall of the nasal cavity and consists of a lamina of spongy bone, curled upon itself like a scroll, (turbinate meaning inverted cone). [ 1 ]
The frontonasal duct is a duct through which either frontal sinus drains into the nasal cavity. [2][3] Each frontal sinus opens into the frontonasal duct by an opening (the opening of frontal sinus or frontal sinus aperture[4]) on the inferomedial part [3] of the floor of the sinus. [4] The frontonasal duct passes inferior-ward [5] to open ...
A curved lamina, the uncinate process, projects downward and backward from this part of the labyrinth; it forms a small part of the medial wall of the maxillary sinus, and articulates with the ethmoidal process of the inferior nasal concha. [1] The medial surface of the labyrinth forms part of the lateral wall of the corresponding nasal cavity.
Ethmoid bulla. The ethmoid bulla (or ethmoidal bulla) is a rounded elevation upon the lateral wall of the middle nasal meatus [1][2]: 377 (nasal cavity inferior to the middle nasal concha) produced by one or more of the underlying middle ethmoidal air cells (which open into the nasal cavity upon or superior to the ethmoidal bulla [2]: 374 [3 ...
