    sesses but little sensibility. It is the nutrient mennbrane of the bone, endowing its exterior with vitality; it also gives insertion to the tendons and connecting ligaments of the joints. 74. There are two hundred and eight* bones in the human body, beside the teeth. These, for convenience, are divided into four parts : 1st. The bon^s of the Head. 2d. The bones of the Trunk. 3d. The bones of the Upper Extremities. 4th. The bones of the Lower Extremities. 75. The bones of the head are divided into those of the Skull^ Ear^ and Face. 76. The SKULL is composed of eight bones. They are formed of two plates, or tablets of bony matter, united by a porous portion of bonp. The external tablet is fibrous and tough ; the internal plate is dense and hard, and is called the vit're-ouSf or glassy table. These tough, hard plates are adapted to resist the penetration of sharp instruments, while the different degrees of density possessed by the two tablets, and the iatervening spongy bone, serve to diminish the vibrations that would,occur in falls or blows. 77. The skull is convex externally, and at the base much thicker than at the top or sides. The most important part of the brain is placed here, completely out of the way of injury unless of a very serious nature. The base of the cranium or skull, has many projections, depressions, and apertures; the latter affording passages for the nerves and blood- vessels. * Some anatomists reckon more than this number, others less, for the reason that, at different periods of life, tlie number of pieces of which one bone is formed, varies. Example. The breast-bone, in infancy, has eiffht jiicces; in youth, three; in old age, but one. 74. How many bones in the human body ? How are they divided ? 75—81. Give the anatomy of the bones of the head. 75. How are the bonea of the head divided ? 76. Describe the bones of the skull. 77. What is the form of the skull ? What does the base of the skull present ?
