The inferior turbinated are two irregular, scroll-likebones situated in the nasal cavities. They are spindle-shaped in outline, and run horizontally along the outerwall of the nose. The bones consist of a quadrilateral,vertical plate, about three-quarters of an inch square;from its inner surface the turbinated portion curves in-ward and downward. The vertical plate presents forexamination an external and internal surface, and irregu- lar borders. The external surface is rough, for articula-. (Inner surface.) (Outer surface.)

The inner surface of the verticalplate forms part of the external wall of the nose. Pro-jecting from the anterior border of the vertical plate isthe lachrymal process, a vertical lamella of bone, whicharticulates with the lower border of the lachrymal. Theanterior border articulates with the posterior edge of thenasal process, completing the lachrymal canal. Theturbinated portion is spindle-shaped, strongly curvedinward, downward, and outward; rougher and moreirregular on the inner convex than on the outer orunder concave surface. The extremities -are pointed,the posterior sharper than the anterior. The upperborder of the turbinated portion, in front of the vertical 54 PRACTICAL ANATOMY. plate, articulates with the inferior turbinated crest of thesuperior maxillary, with the lachrymal and
