| growing fracture | Linear skull fracture in a young child which increases in size, usually as the result of an associated dural tear and arachnoid cyst formation within the fracture line. (05 Mar 2000) |
| growing ovarian follicle | A follicle having several layers of proliferating follicular cells surrounding the ovum, but separated from it by an extracellular glycoprotein layer (zona pellucida). (05 Mar 2000) |
| growing pains | Mysterious pains in growing children, usually in the legs. These pains are similar to what the weekend gardener suffers from on monday an overuse type of problem. If in playing, children exceed their regular threshold, they will be sore, just like an adult. Growing pains are typically somewhat diffuse (vs. Focal) and are not associated with physical changes of the area (such as swelling, redness, etc.). The pains are usually easily relieved by massage, tylenol (acetaminophen), or rest. If the pains persist past a week or there are physical changes, the child should be seen by a physician.

| growth | 1. The process of growing; the gradual increase of an animal or a vegetable body; the development from a seed, germ, or root, to full size or maturity; increase in size, number, frequency, strength, etc.; augmentation; advancement; production; prevalence or influence; as, the growth of trade; the growth of power; the growth of intemperance. Idle weeds are fast in growth. 2. That which has grown or is growing; anything produced; product; consequence; effect; result. "Nature multiplies her fertile growth." (Milton) Origin: Icel.

| growth and embryonic development | Developmental processes from cell division to embryogenesis to postnatal growth and maturity. (12 Dec 1998) |
| growth arrest lines | Dense lines parallel to the growth plates of long bones on radiographs, representing temporary slowing or cessation of longitudinal growth. Synonym: Harris' lines. (05 Mar 2000) |
| growth associated proteins | <growth factor> Group of developmentally regulated polypeptides thought to be critical for the formation of neural circuitry. The acidic membrane phosphoprotein GAP 43 is synthesised and transported down regenerating and developing axons, pp46 localised in growth cone membranes during embryogenesis, B 50 in mature presynaptic membranes in the regulation of phosphotidylinositol turnover and F1 in the hippocampus during long-term potentiation, are now all known to be the same protein. (18 Nov 1997) |
| growth cone | <cell biology> A specialised region at the tip of a growing neurite that is responsible for sensing the local environment and moving toward the neuron's target cell. Growth cones are hand shaped, with several long filopodia that differentially adhere to surfaces in the embryo. Growth cones can be sensitive to several guidance cues, for example: surface adhesiveness, growth factors, neurotransmitters and electric fields (galvanotropism). (18 Nov 1997) |
| growth cone collapse | <cell biology> Loss of motile activity and cessation of advance by growth cones. There are now thought to be specific molecules that inhibit the motility of particular growth cones and are important in establishing correct pathways in developing nervous systems. See: axon pathfinding. (18 Nov 1997) |
| growth control | <cell biology> When applied to cells usually means control of growth of the population, i.e. Of the rate of division rather than of the size of an individual cell. (18 Nov 1997) |
| growth curve | A graphic representation of the change in size of an individual or a population over a period of time. (05 Mar 2000) |
| growth disorders | Deviations from the average values for a specific age and sex in any or all of the following: height, weight, skeletal proportions, osseous development, or maturation of features. The concept includes both acceleration and retardation of growth. (12 Dec 1998) |
