title: [The human head, a cognitive and communicative system. Practical applications].
abstract: The human face is a sensory complex with the task of transmitting to the central nervous system most of the information and signals from the surroundings. This perceptive centripetal activity is linked with continual centrifugal transmissions to the surroundings of a relational type. The cerebral extremity of a human being is ethological in essence. The human cephalic phenotype is, during the whole of its development, a succession of responses of the genome to the stresses of the environment: it is an open system. The phylogenesis of the cerebral cognitive organs and the phylogenesis of the skeleton which protects them are linked. The growth of the membranous cephalic skeleton is under the control of these cognitive organs. Practical applications are deduced from this in connection with the pre-operative functional test for prognathisms.
