Sensitivity (other)
Sensitivity may refer to: Science and technology Natural sciences * Sensitivity (physiology), the ability of an organism or organ to respond to external stimuli ** Sensory processing sensitivity, a personality trait in humans * Sensitivity and specificity, statistical measures of the performance of binary classification tests * antimicrobial susceptibility, often called "sensitivity" * Allergic sensitivity, the strength of a reaction to an allergen * The inverse of resistance (ecology), the ability of populations to remain stable when subject to disturbance Electronics * Sensitivity (electronics). Two contrasting definitions of sensitivity are used in the field of electronic sensors and instruments ** Sensitivity first definition: the ratio between output and input signal, or the slope of the output versus input response curve of a transducer, microphone or sensor ** Sensitivity second definition: the minimum magnitude of input signal required to produce an output signal wit ...

Sensitivity (physiology)
In physiology, a stimulus is a change in a Organism, living thing's internal or external Environment (systems), environment. This change can be Sense, detected by an organism or organ using sensitivity, and leads to a physiological reaction. Sensory receptors can receive stimuli from outside the body, as in Somatosensory system, touch receptors found in the skin or light receptors in the eye, as well as from inside the body, as in chemoreceptors and mechanoreceptors. When a stimulus is detected by a sensory receptor, it can elicit a Reflex action, reflex via Transduction (physiology), stimulus transduction. An internal stimulus is often the first component of a Homeostasis, homeostatic control system. External stimuli are capable of producing systemic responses throughout the body, as in the fight-or-flight response. In order for a stimulus to be detected with high probability, its level of strength must exceed the absolute threshold; if a signal does reach threshold, the informa ...
