What type of bone is the inferior nasal concha?
Summary. The inferior nasal concha is the most caudally based of the three nasal conchae and sits on the vertical bony plate known as the nasal septum. The pair of inferior nasal conchae mature via endochondral ossification. Its articulating bony structures include:
What is the function of nasal conchae?
It helps to filter and humidify the air that we breathe. The nasal conchae (plural of concha) are also sometimes called turbinates. The inferior nasal conchae are a pair of bones, with one concha on either side, that separates the middle and lower nasal meatus, or nasal cavity. They are often described as being "spongy" bones.

Which of the following is a facial bone?
Answer: (D). The zygomatic bone, also called cheekbone or malar bone, is located below and lateral to the orbit (eye socket), at the widest part of the cheek. It joins the frontal bone at the outer edge of the orbit and the sphenoid and maxilla within the orbit.
Where is the superior nasal concha?
Description. The back part of the medial surface of the labyrinth of ethmoid is subdivided by a narrow oblique fissure, the superior meatus of the nose, bounded above by a thin, curved plate, the superior nasal concha. The bone found in superior nasal concha is part of the ethmoid bone.
What makes up inferior nasal concha?
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).
Is ethmoid a facial bone?
The ethmoid bone is a single midline facial bone that separates the nasal cavity from the brain and is located at the roof of the nose and between the orbits. It is a cubical shape and is relatively lightweight because of its spongy construction and air-filled sinuses. It contributes to the anterior cranial fossa.

What is the foramen of the facial bones?
Foramina in the facial bones, such as the zygomaticofacial foramen in the zygomatic bone, allow blood vessels and nerves to travel through the facial skeleton. Grooves also create channels through which soft tissue can travel, and indentations for other structures, such as the facial bone paranasal sinuses.
How Many Facial Bones Are There?
If you are asked how many facial bones there are, there is no fixed answer. This is because, as already mentioned, some bones of the face are also part of the neurocranium (the bony covering of the brain ). Alternatively, some anatomists do not count the mandible, as this bone is only attached to the skull via ligaments (at the temporomandibular joint); it only directly joins to its paired half through the length of the chin.
What bones are not included in the facial diagram?
The above facial bone diagram does not include the ethmoid and sphenoid bones. They are only labeled as part of the cranium.
Why do we have multiple bones in our face?
The form of your face is largely due to the shape of your facial skeleton. These multiple bones also feature foramina (holes) that allow important cranial nerves and blood supply to cross from the inside to the outside surfaces and vice versa. Each bone articulates (joins) with neighboring bones.
What bone is responsible for the high cheekbones?
The size of the zygomatic bone defines whether we have high cheekbones or not. The alveolar bone of the upper and lower jaw provides sockets for our teeth. A facial fracture, therefore, can cause a whole range of symptoms and short- or long-term complications.
Which skeleton supports the upper lip?
It is our facial skeleton that supports the skin and mucous membranes. The maxilla supports the upper lip, the mandible the lower lip. The nasal bones and vomer provide attachment points for the cartilage of the septum and nose tip. The size of the zygomatic bone defines whether we have high cheekbones or not.
Which bones articulate directly with their opposite partner?
Only articulates directly with its opposite partner at the chin; forms a synovial joint with the temporal fossa of the temporal bone (temporomandibular joint). To receive optimum points, a diagram with labeled facial bones will show that you understand how each bone contributes to the face. Labeled bones of the neuro- and viscerocranium.
What are the Facial Bones
The human skull is comprised of 22 bones, among which there are 14 facial bones that form the front portion of the skull, which is the facial skeleton or viscerocranium. There are six paired and two single facial bones, which become 14 in total. Among them, some are irregular, while some are flat.
Functions
Provide a structural framework for the face. So, the look or form of our face is due to our facial skeleton.

Where are the nasal bones?
The nasal bones. The nasal bones are a pair of bones that sit at the roof of the face and create the initial contour of the nose known as the bridge of the nose. They meet in the midline with one another and additionally articulate with the frontal bone superiorly via the frontonasal suture and the maxilla laterally via the nasomaxillary sutures.
What is the bridge between the neurocranium and the viscerocranium?
The zygomatic bones. The zygomatic bone is the bridge between the neurocranium and the viscerocranium. It forms the lateral prominences of the face (“ cheekbones ”) where the zygomatic and temporal portions of the zygomatic arch meet each other.

What happens if you remove the inferior nasal concha?
Removing too much of the inferior nasal concha can impair its ability to humidify the air we breathe and results in a condition called dry nose syndrome or empty nose syndrome. 6 . After surgery to reduce the inferior nasal concha you can expect to have some pain and burning in your nose or sinuses.
How is nasal concha surgery done?
The procedure is usually performed using an endoscope. The surgeon goes in through the nostrils so no external incision needs to be made.

What is the function of cilia in the nasopharynx?
Cilia are tiny hairs that function to sweep mucus and filtered debris towards the nasopharynx where it can be swallowed, (rather than entering the lungs).
Can a concha be chronic?
Enlarged nasal concha, (also called turbinate hypertrophy or just enlarged turbinates), may be temporary or chronic depending on the root cause. Upper respiratory infections and the common cold are typically to blame and you may periodically experience temporary enlargement of your nasal concha throughout your life.
