Central Core (Neuman)

The basic structure, or central core, is made up of the basic survival factors that are common to the species (Neuman, 1995, in George, 1996). These factors include: system variables, genetic features, and the strengths and weaknesses of the system parts. Examples of these may include: hair color, body temperature regulation ability, functioning of body systems homeostatically, cognitive ability, physical strength, and value systems. The person's system is an open system and therefore is dynamic and constantly changing and evolving. Stability, or homeostasis, occurs when the amount of energy that is available exceeds that being used by the system. A homeostatic body system is constantly in a dynamic process of input, output, feedback, and compensation, which leads to a state of balance.e here!
