Somesthesy
The somesthesy (known as also sensitivity of the body ) constitutes one of the sensory systems of the organization.
The somesthesy indicates a whole of various feelings (pressure, heat, pain…) who are elaborate starting from the furnished informations by many sensitive receivers of the system somatosensoriel located in various fabrics of the organization (Mécanorécepteur of the Derme, the Viscères, Thermorécepteur S of language… etc).
These receivers consist of peripheral sensitive neurons which will join marrow or the medulla. The cellular bodies of these receiving neurons are placed in the spinaux ganglia (or the " ganglion of Gasser" for the sensitivity of the face). Information will walk on, after relay in thalamus, to the parietal cortex, sits of integration. There exist two types of sensitivity conveyed by neurons belonging to different systems: the system lemniscal and the system extralemniscal (spino-thalamic). First is responsible for the fine and discriminative tactile sensitivity but also for the articular sensitivity. Second is responsible for the thermal sensitivity, of the coarse tactile sensitivity as well as pain.
