The basic principle of homeostasis is when there is an abnormal internal condition‚ it will be detected and a variation

Several researchers published an empirical article called the “Comparison of the Effects of Hydration with Water or Isotonic Solution on the Recovery of Cardiac Autonomic Modulation”. The purpose of this study was to determine the importance of hydrating after strenuous activity. The ideal time that someone hydrates by drinking water‚ Gatorade‚ or any other sport drink is unclear. The researchers do know‚ however‚ that hydration helps with tolerance to strenuous activity because it helps regulate

TMA 2 Part 1 Describe how neurons in the central nervous system communicate. Using examples‚ discuss how this has helped us to understand human behaviour. Human cognition‚ emotion‚ motivation and ultimately life is made possible by neurons in the central nervous system (CNS). This essay will briefly describe the processes involved in neuronal communication and discuss how this knowledge has helped improve our understanding of human behaviour‚ specifically with regards to neurological
