Ontology: Touch sensation (C0702221)
| Definition (MSH) | Sensation of making physical contact with objects, animate or inanimate. Tactile stimuli are detected by MECHANORECEPTORS in the skin and mucous membranes. |
| Definition (GO) | The series of events required for an organism to receive a touch stimulus, convert it to a molecular signal, and recognize and characterize the signal. This is a neurological process. The perception of touch in animals is mediated by mechanoreceptors in the skin and mucous membranes and is the sense by which contact with objects gives evidence as to certain of their qualities. Different types of touch can be perceived (for example, light, coarse, pressure and tickling) and the stimulus may be external or internal (e.g. the feeling of a full stomach). [GOC:ai] |
| Definition (NCI) | The faculty of touch, the sensation produced by pressure receptors in the skin. |
| Definition (PSY) | Awareness of the qualities or characteristics of objects, substances, or surfaces by means of touch. |
| Definition (CSP) | group of senses by which contact with objects gives evidence as to certain of their qualities, as registered by mechanoreceptors in the skin and mucous membranes. |
