The agger nasi is a small ridge on the lateral side of the nasal cavity. It is located midway at the anterior edge of the middle nasal concha, directly above the atrium of the middle meatus. It is formed by a mucous membrane that is covering the ethmoidal crest of the maxilla. The nasal cavity (or nasal fossa) is a large air-filled space above and behind the nose in the middle of the face. ... The mucous membranes (or mucosae; singular: mucosa) are linings of ectodermic origin, covered in epithelium, and are involved in absorption and secretion. ... The maxillae are the largest bones of the face, except for the mandible, and form, by their union, the whole of the upper jaw. ...
It is also called the nasoturbinal concha and the nasal ridge.

ethmoid bone: Cribriform plate | Crista galli | Perpendicular plate | Labyrinth | Ethmoid sinus | Uncinate process | Middle nasal concha | Superior meatus | Superior nasal concha | Middle meatus Your skull is in your back (this is obviously not true, I was just testing the website to see if it really works) The ethmoid bone (os ethmoidale) is a bone in the skull that separates the nasal cavity from the brain. ... The ethmoid bone (os ethmoidale) is a bone in the skull that separates the nasal cavity from the brain. ... The crista galli (Latin: crest of the cock) is a median ridge of bone that projects from the cribriform plate of the ethmoid bone. ... ethmoidal sinuses can be divided into 3: a) anterior b) middle c) posterior except the posterior ethmoidal sinus, all the ethmoidal sinuses will drain into middle meateus. ... An uncinate process is a hook shaped process on the lateral borders of the superior surface of the bodies of C3-C6 (T1). ...
mandible: Symphysis menti | Mental foramen | Mylohyoid line | Ramus mandibulae | Mandibular foramen | Mandibular canal The mandible (inferior maxillary bone) (together with the maxilla) is the largest and strongest bone of the face. ... The external surface of the mandible is marked in the median line by a faint ridge, indicating the Symphysis menti or line of junction of the two pieces of which the bone is composed at an early period of life. ... The mental foramen is a foramen in the mandible. ... The Mandibular Foramen is an opening on the internal surface of the ramus for the mandibular vessels and nerve to pass. ...
others:nasal bone | inferior nasal conchae | vomer bone The Nasal Bones (Ossa Faciei & Ossa Nasalia) are two small oblong bones, varying in size and form in different individuals; they are placed side by side at the middle and upper part of the face, and form, by their junction, the bridge of the nose. ... It has been suggested that this article or section be merged with Nasal concha. ... The vomer bone is one of the unpaired facial bones of the skull. ...
Asterion | Nasion | Pterion | Dacryon | Inferior orbital fissure The nasion (nay-zhun) is the intersection of the frontal and two nasal bones of the human skull. ... The point corresponding with the posterior end of the sphenoparietal suture is named the pterion; it is situated about 3 cm. ...
The passage from the frontal sinus to the hiatus semilunaris is known as the infundibulum, and into this open the anterior ethmoidal cells, so that the antrum acts as a sink for the secretion of these cells and of the frontal sinus.
Running downward and forward from the front of the middle turbinated bone is a curved ridge known as the aggernasi, which forms the anterior boundary of a slightly depressed area called the atrium.
Free dissection of the re Olfactory dundant tissue from arotind the nasal pit cartilages is necessary in lipoma nasi, skin being grafted on to the raw surface.
