In addition to influencing growth directly, the pituitary gland has a central role in regulating the other endocrine glands. These other glands in turn control many body functions, and they secrete the various hormones that directly regulate metabolism.
Growth in height occurs as a result of maturation of the skeleton. When the long bones have reached maturity at about age 18, linear growth stops. In general, the birth weight of the average baby doubles in 5 to 6 months and triples by the end of the first year. At the end of the second year of life birth weight quadruples and then there is a steady increase of 2 to 2.75 kg (4.4 to 6 lb.) each year until the child reaches puberty, at which time there is a period of rapid growth in weight and height.
growththe process of increase in size which has three distinct components,
- cell division,
- cell expansion. The basis of growth is CELL DIVISION but in order to increase in size, cells must be able to synthesize new structures that are manufactured from raw materials derived from their immediate environment. This is assimilation and it results in increase in cell size. Growth during development can be continuous but allometric (see ALLOMETRIC GROWTH), as in humans, or can be discontinuous, as in insects where growth occurs at each ECDYSIS.
