Sternum
the breast bone; in man, the flat bone, occupying the front of the chest, and formed by the meeting of the visceral arches. It is flattened from before background, and presents a slight vertical curve with the convexity in front. It is divided into the manubrium or presternum, the mesosternum, and the ensiform or xiphoid process of metasternum. All mammals and birds possess a sternum, and the presence or absence of a keel on that bone in birds is used as a means of classification. Fishes, amphibians, and ophidians have no sternum, and in saurians the broad portion is generally expanded. Some suppose that the plastron of the Chelonia is a highlydeveloped sternum; others hold that it is a mere integumentary ossification. The name sternum is also given to the plate on each segment of the breast of a crustacean and an arachnidan, but these are integumentary, and have no relation to a true sternum.

Stethoscope
an instrument employed in auscultation. It was invented by Lænnec, who at first used a roll of blotting paper for the purpose of concentrating and conveying sound to the ear; but, according to i to Tyndall, the philosophy of the stethoscope was enunciated by Dr. Robert Hooke (1635-1702). The common stethoscope consists of a hard rubber funnel to which two flexible rubber eartubes are attached. The funnel is applied to the chest, and the tubes to the ear of the physician who perceives the condition of the lungs by the sounds produced when the patient draws long breaths. The phoneidoscope is an improvement which conveys the most minute sounds to the ear.
