The septal nasal cartilage (cartilage of the septum or quadrangular cartilage) is composed of hyaline cartilage. [1] It is somewhat quadrilateral in form, thicker at its margins than at its center, and completes the separation between the nasal cavities in front.
Septal nasal cartilage (ie, quandrangular cartilage) Vomer bone; The lowest part of the septum is a narrow strip of bone that projects from the maxilla and the palatine bones, and is the length of the septum. This strip of bone is called the maxillary crest; it articulates in front with the septal nasal cartilage, and at the back with the vomer ...
Right side view of the septal nasal cartilage. The septal nasal cartilage is a flat, quadrilateral piece of hyaline cartilage that separates both nasal cavities from one another. [3] The septal nasal cartilage fits in a place between the perpendicular plate of the ethmoid and vomer bones while also being covered by an internal mucous membrane ...
There is a narrow strip of cartilage called the vomeronasal cartilage that lies between the vomer and the septal cartilage. [9] The septal nasal cartilage, extends from the nasal bones in the midline, to the bony part of the septum in the midline, posteriorly. It then passes along the floor of the nasal cavity. [10] The septum is quadrangular ...
Harvesting of nasal cartilage is minimally invasive, can be performed in an outpatient procedure under local anesthesia and is associated with minimal morbidity. [6] NC can be isolated from nasal septal cartilage biopsies by enzymatic digestion using collagenase type I, II or IV (at different combination and concentration – varying from 0.15% to 0.6% –) alone or after an initial short pre ...
It is located in the midsagittal line, and articulates with the sphenoid, the ethmoid, the left and right palatine bones, and the left and right maxillary bones. The vomer forms the inferior part of the nasal septum in humans, with the superior part formed by the perpendicular plate of the ethmoid bone . [ 3 ]
Hyaline cartilage is the most common kind of cartilage in the human body. [2] It is primarily composed of type II collagen and proteoglycans. [2] Hyaline cartilage is located in the trachea, nose, epiphyseal plate, sternum, and ribs. [2] Hyaline cartilage is covered externally by a fibrous membrane known as the perichondrium. [2]
Hyaline cartilage has fewer cells than elastic cartilage; there is more intercellular space. Hyaline cartilage is found in the nose, ears, trachea, parts of the larynx, and smaller respiratory tubes. Fibrous cartilage has the fewest cells so it has the most intercellular space. Fibrous cartilage is found in the spine and the menisci.
