state

 [stāt]
condition or situation.
alpha state the state of relaxation and peaceful awakefulness associated with prominent alpha brain wave activity.
anxiety state the condition of experiencing undue anxiety, as in anxiety disorders.
excited state the condition of a nucleus, atom, or molecule produced by the addition of energy to the system as the result of absorption of photons or of inelastic collisions with other particles or systems.
ground state the condition of lowest energy of a nucleus, atom, or molecule.
persistent vegetative state a condition of profound nonresponsiveness in the wakeful state caused by brain damage at whatever level and characterized by a nonfunctioning cerebral cortex, the absence of any discernible adaptive response to the external environment, akinesia, mutism, and inability to signal; the electroencephalogram may be isoelectric or show abnormal activity. Vegetative states raise ethical questions regarding appropriate care, use of resources, and allowing a patient to die.
refractory state a condition of subnormal excitability of muscle and nerve following excitation.
resting state the physiologic condition achieved by complete bed rest for at least 1 hour.
steady state dynamic equilibrium.

ex·cit·ed state

the condition of an atom or molecule after absorbing energy, which may be the result of exposure to light, electricity, elevated temperature, or a chemical reaction; such activation may be a necessary prelude to a chemical reaction or to the emission of light.
Synonym(s): activated state

excited state

[eksī′tid]
Etymology: L, excitare, to rouse, status
(in chemistry and physics) an energy level of a system that is higher than the ground state. The system decays to the ground state and emits the energy difference, usually in the form of photons.

The condition of an atom or molecule after absorbing energy, which may be the result of exposure to light, electricity, elevated temperature, or a chemical reaction; such activation may be a necessary prelude to a chemical reaction or to the emission of light.
