Thermoreceptors-+Fevers+WB

Thermoreceptors are parts of the human body which sense temperature. The temperature reading provided my thermoreceptors can come from either inside, or outside the body. Thermoreceptors are located all throughout the skin, but mostly in the brain. Thermoreceptors sense changes in internal or external temperatures, and send messages to the central nervous system when the body temperature, or "core" temperature needs to be adjusted. Once these messages are sent to the central nervous system, the body reacts by rapidly heating or cooling itself. The body heats itself by increasing heart rate, shivering, or closing pores. The body cools itself by sweating, or slowing heart rate. When someone gets a fever, their thermoreceptors sense that the body is too cold. In some cases, the body does actually cool off, and needs to be heated. In other cases, however, the thermorecptors can tell the body to heat, even when it doesn't need to. A fever occurs when: When the body is ill, a fever occurs when the signal between the thermoreceptors and the central nervous system is weak, or incorrect. This causes the body to heat to an uncomfortable point, which can be incredibly dangerous for one's health.
