Oleron, the Uliarus Insula of Pliny, formed part of theduchyof Aquitaine, and finally came into the possession of the Frenchcrown in 1370. It gave its name to a medieval code of maritimelaws promulgated by Eleanor of Guienne. OLFACTORY SYSTEM, in anatomy. The olfactory systemconsists of the outer nose, which projects from the face, and thenasal cavities, contained in the skull, which support the oifactorymucous membrane for the perception of smell in their upperparts, and act as respiratory passages below. The bony framework of the nose is part of the skull (), but theouter nose is only supported by bone above; lower down itsshape is kept by an upper and lower lateral cartilage andtwo or three smaller plates known as cartilagines minores. Nasal bone Nasal process ofsuperior maxilla. From R. Howden, in Cunninghams Text-Book of Anatomy. Fig. 1.—Profile View of the Bony and Cartilaginous Skeleton ofthe Nose. The expanded lower part of the side of the outer nose is knownas the ala and is only formed of skin, both externally andinternally, with fibro-fatty tissue between the layers. The innernose or nasal cavities are separated by a septum, which is seldomquite median and is covered in its lower two-thirds by thick,highly vascular mucous membrane composed of columnarciliated epithelium with masses of acinous glands (see EpithelialTissues) embedded in it, while in its upper part it is coveredby the less vascular but more specialized olfactory the front of the lower part of the septum a slight openinginto a short blind tube, which runs upward and backward, maysometimes be found; this is the vestigial remnant of Jacobsonsorgan, which will be noticed later.
