The inferior nasal conchae are considered a pair of facial bones. … Superior to inferior nasal concha are the middle nasal concha and superior nasal concha which arise from the cranial portion of the skull. Hence, these two are considered as a part of the cranial bones.
Which bones make the nasal conchae?
While the superior and middle nasal conchae are technically part of the ethmoid bone, the inferior nasal concha forms a completely separate bone.
What makes up the middle nasal concha?
The middle nasal concha consists of the medial surface of the labyrinth of ethmoid which is a thin basal lamella that descends from the undersurface of the cribriform plate and ends in a free, convoluted margin.
Is the middle nasal concha a bone?
The middle concha covers the expanded bulla ethmoidalis and the groove beneath it, the hiatus semilunaris. A curved piece of bone, the uncinate process, which usually articulates with both the lacrimal and the inferior concha and partly covers the opening of the maxillary sinus, extends posteriorly under the bulla.Where is inferior nasal concha located?
Inferior nasal conchae extend horizontally along the lateral walls of the nasal cavity, articulating with the medial wall of the maxillae and with the palatines. They also articulate with the ethmoid and lacrimals superiorly. The bones are rarely found isolated because they are so fragile.
Where are the nasal Conchae quizlet?
Nasal conchae are curved shelves of bone that project out of the lateral walls of the nasal cavity that create four pathways (meatuses) for air to flow.
Where is the nasal conchae located?
The conchae are located laterally in the nasal cavity and covered by pseudostratified columnar, ciliated respiratory epithelium with a thick, vascular and erectile glandular tissue layer.
What is the maxillary bone?
Overview. The maxilla is the bone that forms your upper jaw. The right and left halves of the maxilla are irregularly shaped bones that fuse together in the middle of the skull, below the nose, in an area known as the intermaxillary suture. The maxilla is a major bone of the face.Where are the maxillary sinuses?
A type of paranasal sinus (a hollow space in the bones around the nose). There are two large maxillary sinuses, one in each of the maxillary bones, which are in the cheek area next to the nose. The maxillary sinuses are lined with cells that make mucus to keep the nose from drying out.
What is a nasal concha?nasal concha, also called Turbinate, or Turbinal, any of several thin, scroll-shaped bony elements forming the upper chambers of the nasal cavities. They increase the surface area of these cavities, thus providing for rapid warming and humidification of air as it passes to the lungs.
Article first time published onWhat is superior nasal concha?
The superior nasal conchae or turbinates form one of the three pairs of conchae in the nose and represent part of the labyrinth of the ethmoid bone, arising as bony projections from its posterior surface.
What are the fourteen facial bones?

What is the basic structure of the nasal Conchae?
Structure. Conchae are composed of pseudostratified columnar, ciliated respiratory epithelium with a thick, vascular, and erectile glandular tissue layer. The conchae are located laterally in the nasal cavities, curling medially and downward into the nasal airway.
How many conchae are in the nasal cavity?
Nasal Conchae They are called conchae (or turbinates). The are three conchae – inferior, middle and superior. They project into the nasal cavity, creating four pathways for the air to flow.
What is nasal Conchae quizlet?
What is the function of the nasal conchae? The nasal cavity is divided in two by a bone and a cartilage mucous-lined septum. The nasal conchae increases the cavity’s surface area and creates air turbulence to filter, warm or cool, and humidify the air.
In which bone do you find the superior and middle nasal Conchae?
The superior nasal concha and middle nasal concha are parts of the ethmoid bone.
Which contains the vocal cords?
Larynx — also known as the voice box, the larynx is a cylindrical grouping of cartilages, muscles and soft tissue that contains the vocal cords. The larynx is the upper opening into the windpipe (trachea), the passageway to the lungs.
Where is the maxillary ostium?
The first, the maxillary ostium, is located on the superomedial aspect of the maxillary sinus. The ostium leads into the second passage, the ethmoid infundibulum, that conducts mucus from the maxillary sinus into the middle meatus via the third passage, the hiatus semilunaris.
Where is the left maxillary antrum?
The maxillary sinus (or antrum of Highmore) is a paired pyramid-shaped paranasal sinus within the maxillary bone which drains via the maxillary ostium into the infundibulum, then through hiatus semilunaris into the middle meatus. It is the largest of the paranasal sinuses.
What are the 4 types of sinuses?
The word “sinus” is most commonly understood to be the paranasal sinuses that are located near the nose and connect to the nasal cavity. There are four paranasal sinuses, each corresponding with the respective bone from which it takes its name: maxillary, ethmoid, sphenoid, and frontal.
Is the maxilla a facial bone?
The primary bones of the face are the mandible, maxilla, frontal bone, nasal bones, and zygoma. Facial bone anatomy is complex, yet elegant, in its suitability to serve a multitude of functions.
Where is the maxillary bone located?
The maxilla is a bone which helps to make up the skull. It is specifically located in the mid face, forms the upper jaw, separates the nasal and oral cavities, and contains the maxillary sinuses (located on each side of the nose.
Is the maxilla one or two bones?
Anatomical terms of bone The maxilla (plural: maxillae /mækˈsɪliː/) in vertebrates is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth.
Is the nasal concha the same as turbinate?
Within the nasal cavity, there are three separate turbinates: superior, middle, and inferior. Turbinates are also called concha. … The inferior turbinate is independent of the superior and middle turbinates that extend from the ethmoid bones. The space between each turbinate and the nasal wall is called a meatus.
Are turbinates Conchae?
turbinates (turbinate bones or nasal conchae) are thin, curved, bony plates that project from the walls of the nasal cavity into the respiratory passageway.
Is the superior nasal concha part of the sphenoid bone?
Superior nasal conchaFMA57458Anatomical terms of bone
Where is the paranasal sinus?
One of many small hollow spaces in the bones around the nose. Paranasal sinuses are named after the bones that contain them: frontal (the lower forehead), maxillary (cheekbones), ethmoid (beside the upper nose), and sphenoid (behind the nose).
On what bone are the superior nasal conchae found quizlet?
The inferior portion of the sphenoid bone forms the superior nasal concha. The nasal concha are located on the medial wall of the nasal cavity. All of the nasal concha are part of the same bone.
Which are the 8 cranial bones?
- Frontal bone. This is the flat bone that makes up your forehead. …
- Parietal bones. This a pair of flat bones located on either side of your head, behind the frontal bone.
- Temporal bones. …

Which of the following is classified as a facial bone?
Facial Bones. The viscerocranium (face) includes these bones: vomer, 2 inferior nasal conchae, 2 nasals, maxilla, mandible, palatine, 2 zygomatics, and 2 lacrimals.
