Sensitivity, sensitivity in physiology —
- part of the reception perceived by the psyche (of the entire afferent impulsation entering various parts of the central nervous system);
- the ability of the body to perceive irritations emanating from the environment or from its own tissues and organs.
The sensitivity of the organism precedes its reactivity (differentiated response).
Types of sensitivity
General sensitivity
- Superficial (exteroceptive)
- painful
- temperature
- tactile
- Deep (proprioceptive)
- muscular-articular
- vibrating
- kinesthesia — determining the movement of the skin fold
- sense of body weight
- Complex forms of sensitivity
- Interoceptive — due to irritation of the receptors of internal organs.
- Two-dimensional-spatial feeling — a feeling of localization of an injection, touch, recognition of signs and letters written on the skin.
- Discriminatory sensitivity — distinguishing between injections applied at close range (for example, with a Weber compass).
- Stereognosis is the recognition of objects by touch.
Special Sensitivity
- Perception of light — vision
- Sound perception
- Hearing
- Echolocation
- Chemical sensitivity
- Smell
- Taste
- Stereochemical sense (in insects and hammerhead sharks)
- electroreception
- Magnetoreception (in some sharks)
