The accessory nasal cartilages are small cartilages of the nose connecting the greater alar cartilage and lateral nasal cartilage. ... The cartilage of the septum (or septal cartilage, or quadrangular cartilage) is somewhat quadrilateral in form, thicker at its margins than at its center, and completes the separation between the nasal cavities in front. ... The greater alar cartilage (lower lateral cartilage) is a thin, flexible plate, situated immediately below the preceding, and bent upon itself in such a manner as to form the medial wall and lateral wall of the naris of its own side. ... The lateral cartilage (upper lateral cartilage) is situated below the inferior margin of the nasal bone, and is flattened, and triangular in shape. ... The part which forms the lateral wall is curved to correspond with the ala of the nose; it is oval and flattened, narrow behind, where it is connected with the frontal process of the maxilla by a tough fibrous membrane, in which are found three or four small cartilaginous plates... In the septum close to the nasopalatine recess a minute orifice may be discerned; it leads backward into a blind pouch, the rudimentary vomeronasal organ of Jacobson, which is supported by a strip of cartilage, the vomeronasal cartilage (or Jacobsons cartilage). ...

Choana (plural: Choanae) latinization from the Greek choanē meaning funnel is the posterior nasal aperture. ... In anatomy, a turbinate (or nasal concha) is a long, narrow and curled bone shelf (shaped like an elongated sea-shell) which protrudes into the breathing passage of the nose. ... Above the superior concha is a narrow recess, the sphenoethmoidal recess, into which the sphenoidal sinus opens. ... On the lateral wall of the middle meatus is a curved fissure, the hiatus semilunaris, limited below by the edge of the uncinate process of the ethmoid and above by an elevation named the bulla ethmoidalis; the middle ethmoidal cells are contained within this bulla and open on or near... The hiatus semilunaris is a groove in the side wall inside the human nose. ... Below the bulla ethmoidalis, and partly hidden by the inferior end of the uncinate process, is the ostium maxillare (or maxillary sinus ostium, or maxillary ostium, or opening from the maxillary sinus); in a frontal section this opening is seen to be placed near the roof of the sinus. ... The inferior meatus, the largest of the three meatuses of the nose, is the space between the inferior concha and the floor of the nasal cavity. ... The vomeronasal organ (VNO) or Jacobsons organ (sometimes misspelled Jacobsens) is an auxiliary olfactory sense organ in some vertebrates, all of which are tetrapods. ... The paranasal sinuses are eight (four pairs) air-filled spaces, or sinuses, within the bones of the skull and face. ... Beneath the epithelium, and extending through the thickness of the mucous membrane, is a layer of tubular, often branched, glands, the olfactory glands (glands of Bowman), identical in structure with serous glands. ...

Triangles of the neck: Anterior triangle of the neck (Inferior carotid triangle, Superior carotid triangle, Submaxillary triangle, Suprahyoid triangle) - Posterior triangle of the neck (Occipital triangle, Subclavian triangle) Anatomists use the term triangles of the neck to describe the divisions created by the major muscles in the region. ... The anterior triangle is bounded, in front, by the middle line of the neck; behind, by the anterior margin of the Sternocleidomastoideus; its base, directed upward, is formed by the lower border of the body of the mandible, and a line extending from the angle of the mandible to the... The inferior carotid triangle (or muscular triangle), is bounded, in front, by the median line of the neck from the hyoid bone to the sternum; behind, by the anterior margin of the Sternocleidomastoideus; above, by the superior belly of the Omohyoideus. ... The superior carotid triangle (or carotid triangle), is bounded, behind by the Sternocleidomastoideus; below, by the superior belly of the Omohyoideus; and above, by the Stylohyoideus and the posterior belly of the Digastricus. ... The submaxillary triangle (or submandibular or digastric triangle) corresponds to the region of the neck immediately beneath the body of the mandible. ... The Suprahyoid Triangle (or submental triangle) is limited behind by the anterior belly of the Digastricus, in front by the middle line of the neck between the mandible and the hyoid bone; below, by the body of the hyoid bone; its floor is formed by the Mylohyoideus. ... The posterior triangle (or lateral cervical region) is bounded, in front, by the Sternocleidomastoideus; behind, by the anterior margin of the Trapezius; its base is formed by the middle third of the clavicle; its apex, by the occipital bone. ... The occipital triangle, the larger division of the posterior triangle, is bounded, in front, by the Sternocleidomastoideus; behind, by the Trapezius; below, by the Omohyoideus. ... The subclavian triangle, the smaller division of the posterior triangle, is bounded, above, by the inferior belly of the Omohyoideus; below, by the clavicle; its base is formed by the posterior border of the Sternocleidomastoideus. ...
