Milk Feeding

Abstract Major changes occur after the umbilical cord is cut at birth in the structure and function of several physiological systems which enable the newborn baby to adapt from an intrauterine milieu of continuous intravenous nutrition via the placenta to a postnatal environment of intermittent enteral feeding with milk. The secretion of regulatory peptides from the gut and pancreas in response to enteral milk feeding may have a fundamental role in initiating and regulating the cascade of developmental changes needed for the utilization of food which occur after birth.

And Function

The rat is immature at birth and undergoes major developmental changes at the end of the suckling period. This review deals with the maturation of ingestive behavior, gastrointestinal digestive and absorptive functions, liver metabolism, and brain structure and function. Each aspect of development is physiologically correlated with the dietary transition of weaning. However, it is unlikely that the process of weaning acts as a cue for the ontogenic changes. In contrast, there is strong evidence for an important role of both thyroxine and corticosterone as coordinators of maturational events in various organ systems.

Chapter 18 describes important developmental changes in pulmonary structure and function that contribute to changes in the ventilatory response to exercise during growth, describes age and sex differences in the ventilatory response to exercise, provides insights into the developmental aspects of the control of exercise hyperpnoea, explores current issues regarding the ventilatory response to exercise in children, and discusses the potential for training adaptations of pulmonary function during growth.

Insight Into

The synaptic connections in cat retina that link photoreceptors to ganglion cells have been analyzed quantitatively. Our approach has been to prepare serial, ultrathin sections and photograph en montage at low magnification (˜2000X) in the electron microscope. Six series, 100-300 sections long, have been prepared over the last decade. They derive from different cats but always from the same region of retina, about one degree from the center of the visual axis. The material has been analyzed by reconstructing adjacent neurons in each array and then identifying systematically the synaptic connections between arrays. Most reconstructions were done manually by tracing the outlines of processes in successive sections onto acetate sheets aligned on a cartoonist's jig. The tracings were then digitized, stacked by computer, and printed with the hidden lines removed. The results have provided rather than the usual one-dimensional account of pathways, a three-dimensional account of circuits. From this has emerged insight into the functional architecture.
