This two-day symposium in the annual Society for the Study of Human Biology Symposium Series covers a wide spectrum of growth physiology, and presents a state-of-the-art review of human auxology, from factors affecting cellular growth, through nutritional factors affecting the growth of the infant, to endocrine and other factors affecting the growth of the child before and after adolescence. Wiith contributions from some of the leading workers in the various fields, the book starts with a consideration of the effects of experimental removal of parts of mouse embryos on final body size and the part played by local tissue interactions in the specification of limb segments in insects. Discussion of the growth promoting actions of the somatomedins in foetal, postnatal and brain growth follow, leading to two chapters on Man, dealing with energy requirements and body composition in infants, and the endocrine control of body size and sexual development during puberty.
