The Head. The head is the most important part of the 

 body, and to it and to the organs which it contains our 

 attention is most particularly attracted. The heart and 

 lungs support life by the respiration and the circulation, 

 the digestive apparatus nourishes the body, but the head is 

 the seat of intelligence, the centre in which all the nervous 

 impressions meet and from which radiates the will. In the 

 head are united the organs of sight, of hearing, of smell, and 

 of taste ; the face, almost entirely formed by the grouping of 

 these organs, expresses by the aid of numerous muscles the 

 impressions transmitted to the brain, the passions, calmness 

 or agitation of mind, and, within certain limits, the phases 

 of thought. In other regions of the body life is unconscious, 

 and the functions in their performance, whether healthy or 

 diseased, are executed mechanically; the head alone perceives 

 sensations and interprets their meaning, it is by it that man 

 knows himself, by it he feels that he lives, and is able to 

 say, "I think, therefore I am." 



The head is formed of two distinct parts : first, the skull, 

 a bony case which envelops the brain, and incloses in the 

 thickness of one of the bones of which it is formed the organ 

 of hearing; secondly, the face, in which are united the 

 organs of sight, of smell, and of taste. 



The skull is composed of eight bones: the frontal or 

 coronal, which corresponds to the forehead or sinciput; the
