English: A. An example of thermographic film of the tail of a rat placed in a conventional restrainer, recorded with a 320×240 pixels resolution at 1 Hz during 135 minutes. Steel rings maintained its tail. - B. Corresponding temporal evolution of the skin temperature recorded on 6 points distributed from the base to the tip of the tail (blue dots and corresponding traces). One observes phases of vasoconstriction and vasodilatation throughout the recording session. Note that the 10°C amplitude of the variations for the most distal points of the tail. As measured on an inert piece of wood (Ta, lower brown trace), the ambient temperature was stable around 25°C. The central core temperature (Tc) is shown as upper black trace. - C. The dissipation of heat is regulated by abrupt variations of blood flow in a system of arterio-venous anastomoses, which form a double ladder. Anatomy adapted from [58]. |
