Sensors

Sensors A device, such as a photoelectric cell, that receives and responds to a signal or stimulus.
RELATED TERMS--------------------------------------
Cell
Fundamental structural unit of all life. The cell consists primarily of an outer plasma membrane, which separates it from the environment; the genetic material (DNA), which encodes heritable information for the maintainance of life; and the cytoplasm, a heterogeneous assemblage of ions, molecules, and fluid.
SIMILAR TERMS--------------------------------------
Sensate focus
A term introduced by Masters and Johnson to refer to the procedure in sex therapy whereby each partner in turn explores the sensory responsivity of the other, especially through the sense of touch, as in fondling, and stopping short of penovaginal intercourse.
Sensipar
Sensipar is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): cinacalcet hydrochloride.
Sensitivity
1. The reciprocal of the minimum stimulus strength required for the stimulus to be detected reliably (1/threshold) May be related to noise and other mechanisms. 2. Physiologically measured sensitivity averaged over many stimulus/response cycles. A measure of gain. Noise free.
Sensitivity control
Adjustment of eye sensitivity to compensate for a change in illumination.
Sensitization
Potential recipients are "sensitized" if there are antibodies in their blood, usually because of pregnancy, blood transfusions or previous rejection of an organ transplant. Sensitization is measured by PRA. Highly sensitized patients are more likely to reject an organ transplant than unsensitized patients.
Sensorcaine
Sensorcaine is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): bupivacaine hydrochloride.
Sensory extinction
Failure to report sensory stimuli from one region if another region is stimulated simultaneously, even though when the region in question is stimulated by itself, the stimulus is correctly reported.
Sensory fusion
The combining of drawing together of two images which fall on different points in the two retinas without changing the vergence of the two eyes.
PREVIOUS AND NEXT TERMS--------------------------------------
Schatzki's Ring
See lower esophageal ring.
Scintigraphy
See radionuclide scans.
Sclerotherapy
A method of stopping upper GI bleeding. A needle is inserted through an endoscope to bring hardening agents to the place that is bleeding.
Secretin
A hormone made in the duodenum. Causes the stomach to make pepsin, the liver to make bile, and the pancreas to make a digestive juice.
Segmentation
The process by which muscles in the intestines move food and wastes through the body.
Sensors
Septal defect
A hole in the wall of the heart.
Septum
The muscle wall that divides the heart chambers.
Shigellosis
Infection with the bacterium Shigella, usually causing a high fever, acute diarrhea, and dehydration. See also gastroenteritis.
Shock
Impaired body function due to blood loss or a disturbance in the circulatory system.
Short bowel syndrome
Problems related to absorbing nutrients after removal of part of the small intestine. Symptoms include diarrhea, weakness, and weight loss. Also called short gut syndrome.
