growth
The increase in size of a living being or any of its parts occurring in the process of development.
- accretionary g. g. by an increase of intercellular material.
- appositional g. g. accomplished by the addition of new layers on those previously formed; e.g., the addition of lamellae in the formation of bone; it is the characteristic method of g. when rigid materials are involved.
- auxetic g. g. by increase in the size of component cells. SYN: intussusceptive g..
- bacterial g. g. of a bacterial culture either by increase in cell material or cell number.
- differential g. different rates of g. in associated tissues or structures; used especially in embryology when the differences in g. rates result in changing the original proportions or relations.
- exponential g. logarithmic phase.
- interstitial g. g. from a number of different centers within an area; in contrast with appositional g., it can occur only when the materials involved are nonrigid.
- intussusceptive g. SYN: auxetic g..
- multiplicative g. g. by an increase in the number of cells.
- new g. SYN: neoplasm.
