X-ray

DEFINITION:

To examine, treat, or photograph with X rays. X ray:

1. Any of the electromagnetic radiations of the same nature as visible radiation but of an extremely short wavelength less than 100 angstroms that is produced by bombarding a metallic target with fast electrons in vacuum or by transition of atoms to lower energy states and that has the properties of ionizing a gas upon passage through it, of penetrating various thicknesses of all solids, of producing secondary radiations by impinging on material bodies, of acting on photographic films and plates as light does, and of causing fluorescent screens to emit light.

2. A photograph obtained by

use of X rays.

mental retardation

DEFINITION:

A mental disorder characterized by significantly subaverage general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period; classified as...

mild (IQ 50-70) - can develop social and communication skills during the preschool period, have minimal sensorimotor impairment, can by their late teens learn academic skills up to the sixth grade level, and usually achieve social and vocational skills adequate for minimal self-support;

moderate (IQ 35-50) - can talk or learn to communicate but have poor social awareness and only fair motor development, are unlikely to progress to the second grade level in academic skills but can profit from vocational training, and can take care of themselves under supervision;

severe (IQ 20-35) - have poor motor development and minimal speech in the preschool period, may learn to talk by their late teens and can be trained in elementary hygiene skills, and as adults may learn to perform simple work under close supervision;

profound (IQ below 20) - have limited sensorimotor development, may achieve very limited self-care, and require a highly structured environment and constant supervision.

Borderline mental retardation (IQ 70-85), now called borderline intellectual functioning, is used to refer to very mild forms with only slight impairments in adaptive behavior.

Called also mental deficiency or subnormality.
