    grooves for the passage of the nerves and vessels, and are roughened for the attachment of the muscles. Cancellated Structure. The cancellated tissue found be- tween the plates of cortical bone varies in thickness and com- pactness according to the density, the position, and the func- tions of the bone. The arrangement of the trabeculae is an interlacing network. The functions of the cancellated tissue are to give bulk to the bone where required and to diffuse shock. Through it pass the nerves and vessels to supply local structures and, by means of bony canals or tubes, the more distant parts. The bones of the head contain many canals and foramina for this last-named purpose, thus differing ma- terially from the other bones of the body. This is a fact of surgical importance, for when these bones have become al- tered either by breaking down of the tissue or by abnormal growths encroaching upon the foramina or canals, the func- tions of the nerves and vessels are interfered with, thus af- fecting not only adjacent tissues, but as well parts of the face and body remote from the seat of the lesion, causing abnor- malities in the area of distribution, as atrophy, neuralgia, etc.
