Thermoregulation is a critical physiological function that is closely associated with the neonate’s survival. Extremely low birth weight infants have inefficient thermoregulation due to immaturity and care giver procedures such as umbilical line insertions‚ intubations‚ and chest xrays can lead to heat loss as well. As a result‚ infants may exhibit cold body temperatures after birth and during their first 12 hours of life. Thermoregulation plays a unique and crucial role in the nurturing and development

To what extent does heat exposure affect an athlete? Heat exposure is a factor that is essential to be considered by athletes to maximise performance level. Researchers have investigated that excessive heat exposure or exercise hyperthermia has detrimental effects on exercise physiology. Little is understood regarding the effects of hyperthermia and how heat exposure affects the body. Localised heat studies using water immersion to increase muscle temperature have been conducted to investigate the

8. "Thermoregulation" is the process in which your body regulates hypothalamus temperature to its normal body temperature. 9. Hypothalamus is the portion of the brain that contains sensors that monitor body temperature. 10. a) The hypothalamus senses the high temperature so it sends sends to the brain. This creates a reaction as the blood vessels in the skin dilate to radiate heat‚ and sweat glands increase sweat production. b) The two mechanism the body uses to heat itself are when the blood

8. Thermoregulation is the process the body uses in order to keep the body at a regular temperature‚ which is about 37 degrees Celsius. 9. The hypothalamus contains body temperature sensors. 10. a. Two mechanisms the body uses to cool are dilating blood vessels and skin and making sweat glands produce more cooling sweat. b. Two mechanisms the body uses to heat itself are constricting blood vessels and skin and making muscles shiver to produce heat. 11. a. The stimulus is the raised body heat

within a relatively narrow temperature range. Accordingly the human body have anatomical and physiological mechanisms that keep body temperatures within acceptable limits‚ regardless of environmental conditions. This homeostatic process is called thermoregulation and it involves constantly balancing heat-producing and heat-losing mechanisms. If the body temperature is not maintained within these acceptable limits serious physiological changes can occur. If the body temperature falls below 36ºC or goes

HSC OPTION: SPORTS MEDICINE How are sports injuries classified and managed? * Ways to classify sports injuries * Direct and indirect * Direct injuries are sustained from an external force causing injury at the point of contact‚ e.g. a hockey player receiving a bruise from being struck on the leg by a stick during a game. * Indirect injuries usually involve the athlete damaging the soft tissues such as the ligaments‚ tendons or muscles of the body through internal or external forces
