The septal nasal cartilage is also the main structure that provides the orientation of the nose, being the midline structure of the organ. With an offset septal nasal cartilage, the nose will appear crooked to the viewer. A crooked nose can block airflow coming from the nares to the lungs or vice versa. [4]
In most mammals, the philtrum is a narrow groove that may carry dissolved odorants from the rhinarium or nose pad to the vomeronasal organ via ducts inside the mouth. [4]For humans and most primates, the philtrum survives only as a vestigial medial depression between the nose and upper lip.
The vomer (/ ˈ v oʊ m ər /; [1] [2] Latin: vomer, lit. 'ploughshare') is one of the unpaired facial bones of the skull.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.
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 ...
Cartilage inflammation (technically known as chondritis) that is relapsing is very characteristic of the disease. [3] These recurrent episodes of inflammation over the course of the disease may result in breakdown and loss of cartilage. [3] The signs and symptoms of cartilage inflammation in various parts of the body will be described first.
The ala of the nose (ala nasi, "wing of the nose"; plural alae) is the lower lateral surface of the external nose, shaped by the alar cartilage and covered in dense connective tissue. [1] The alae flare out to form a rounded eminence around the nostril. [17] Sexual dimorphism is evident in the larger nose of the male.
The name stands for "mouth and genital ulcers with inflamed cartilage" (relapsing polychondritis). [9] PFAPA syndrome is a rare condition that tends to occur in children. [9] The name stands for "periodic fever, aphthae, pharyngitis (sore throat) and cervical adenitis" (inflammation of the lymph nodes in the neck). The fevers occur periodically ...
The nasal septum is the bone and cartilage in the nose that separates the nasal cavity into the two nostrils.The cartilage is called the quadrangular cartilage and the bones comprising the septum include the maxillary crest, vomer, and the perpendicular plate of the ethmoid.
