Their mustaches were blonde, but Dunham's curled jauntily outward at the corners, and his light hair waved over either temple from the parting in the middle. Staniford's mustache was cut short; his hair was clipped tight to his shapely head, and not parted at all; he had a slightly aquiline nose, with sensitive nostrils, showing the cartilage; his face was darkly freckled.
The ground-substance is in small amount in connective tissues proper, and is obscured by a mass of fibers. It is best seen in hyaline cartilage, where it has a glossy appearance. In bone it is infiltrated with salts which give bone its hardness, and make it seem so unlike other tissues.
Meyer's view, the ear to be made perfect by the equal development of the cartilage throughout the whole extent of the margin, it would have covered fully one-third of the whole ear.
It preserves the form of the body, protects important organs, and supplies the mechanical devices, or machines, upon which the muscles act in the production of motion. The skeleton is adapted to its purposes through the number and properties of the bones, and through the cartilage and connective tissue associated with the bones.
But they had no backbone though we cannot say whether they may not have had a rod of cartilage along the back and no articulated jaws like the fish. Some regard them as a connecting link between the Crustacea and the fishes, but the general feeling is that they were an abortive development in the direction of the fish.
#Primary Tumours Osteoma.# When the tumour projects from the surface of a bone it is called an exostosis. When growing from bones developed in membrane, such as the flat bones of the skull, it is usually dense like ivory, and the term ivory exostosis is employed. When derived from hyaline cartilage for example, at the ends of the long bones it is known as a cartilaginous exostosis.
But both for the attachment of the muscles and the vocal cords themselves solid, relatively hard structures are required. Bone would prove too unyielding, but cartilage, or gristle, meets the case exactly. The entire framework of the larynx its skeleton, so to speak is made up of a series of cartilages united together so as to ensure sufficient firmness with pliability.
The linea fusca, which reaches from the pubes to the navel and occasionally to the ensiform cartilage, is a line of sexual pigmentation sometimes regarded as characteristic of pregnancy, but as Andersen, of Copenhagen, has found by the examination of several hundred children of both sexes, it exists in a slight form in about 75 per cent. of young girls, and in almost as large a proportion of boys.
This she has done in a rather ingenious manner by causing certain of the muscle-rings in the wall of the chest to turn first into gristle, or cartilage, and then later into bone, making what are known as the ribs; these run round the chest much as hoops do round a barrel, or as the whalebone rings did in the old-fashioned hoop skirt.
