The nasal bones are two small oblong bones, varying in size and form in different individuals; they are placed side by side at the middle and upper part of the face and by their junction, form the bridge of the upper one third of the nose. Each has two surfaces and four borders.
The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas).The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine.
The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two. The nose has an important function in breathing.
The vertebral column is often used as a marker of human anatomy. This includes: At C1, base of the nose and the hard palate; At C2, the teeth of a closed mouth; At C3, the mandible and hyoid bone; At C4, the common carotid artery bifurcates. From C4–5, the thyroid cartilage [10] From C6–7, the cricoid cartilage [10]

Because only thin shelves of bone separate the sphenoidal sinuses from the nasal cavities, below, and from the hypophyseal fossa, above, the pituitary gland can be reached surgically through the roof of the nasal cavities by passage through the anterioinferior aspect of the sphenoid bone and into the sinuses, followed by entry through the top ...
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). [ 1 ]
With a collapse of the lateral nasal cartilage, the inner nasal valve could become obstructed and prevent the movement of airflow throughout. [6] A new surgical technique to reposition the lateral nasal cartilage has been constructed to relieve the site of obstruction within the inner nasal valve and regain maximal airflow throughout the nose ...
