The nasion (/ ˈ n eɪ z i ɒ n /) is the most anterior point of the frontonasal suture that joins the nasal part of the frontal bone and the nasal bones. It marks the midpoint at the intersection of the frontonasal suture with the internasal suture joining the nasal bones. [1]

2019年7月5日 · The nasion (also known as bridge of the nose) is the midline bony depression between the eyes where the frontal and two nasal bones meet, just below the glabella. It is one of the skull landmarks: craniometric points for radiological or anthropological skull measurement.

2023年8月14日 · At the nasofrontal suture, the nasal bones fuse with the frontal bone; this is called the nasion. The thickness of the bones differs, but it's the thickest at the nasofrontal suture. The average length of the nasal bones is 2.5 cm. [1] [3]

2024年12月22日 · The nasal bones are two wedged-shaped bones that make up the bridge of your nose. They come together at a rigid fibrous joint, forming the thickest part of the nose. Trauma to the face often involves these bones being injured, and many nasal disorders are related to the structures formed or supported by the nasal bones.

Nasion is the frontmost point of the frontonasal suture. Essentially, it is the point on the forehead where the internasal suture and the frontonasal suture converge.

The nasion is a craniometric point found along the midline on the anterior aspect of the cranium. It is formed by the frontal bone and the right and left nasal bones and is located at the area where the internasal and frontonasal sutures meet.

anatomy of external nose The nose is the first part of the upper respiratory tract and is responsible for warming, humidifying and filtering of inspired air. It contains the peripheral organ of smell.

2025年1月21日 · The nasion is an anatomical landmark located at the intersection of the frontal bone and the two nasal bones of the skull. It is a crucial reference point in both medical and anthropological contexts, often used in the assessment of facial structure and surgical planning.

2022年11月19日 · Thus, the radix extends from the nasion to the sellion. 1 Anthropometrically, the nasion consists of the midpoint of the nasofrontal suture line where the frontal and nasal bones articulate. This is an important landmark because it …

2023年10月30日 · Anatomy, function and location of the nasal bone. The nasal bone is a small, flat bone of the skull. It makes up the facial skeleton (viscerocranium) along with the zygomatic bone, maxillae, palatine bones, lacrimal bones, inferior nasal conchae, vomer and mandible. The nasal bone is located medial to the frontal processes of the maxillae.
