Score is an old word for the number 20. = (4*20+7)years = 87 years. And in the Bible: âthree score years and tenâ meaning: âseventy years oldâ (3*20+10) (Psalm 90). This was thought to be a normal life span.
One of the functions of the Integumentary System is the negative feedback, homeostatic control of the core body temperature. This is called thermoregulation.
The hypothalamus is the temperature-regulating centre of the brain. It contains receptors which are sensitive to the temperature of the blood flowing through the brain. Temperature sensitive receptors in the skin also feed back information to the hypothalamus about the temperature of the skin surface.Changes in core body temperature cause the hypothalamus to send nerve impulses to the sweat glands, muscles and blood vessels to raise or lower the temperature.If the core temperature goes up the body loses heat to bring it down again.hanges in core body temperature cause the hypothalamus to send nerve impulses to the sweat glands, muscles and blood vessels to raise or lower the temperature.
