Document Summary

The endocrine system is responsible for the release and regulation of the hormones that circulate throughout your body. As you may have noticed, it is essential to control the levels of hormones circulating to maintain normal health and homeostasis. Normally, in a healthy person, these levels do not fluctuate too much but are tightly regulated via negative feedback, with a few exceptions. When hormone levels are altered, physiological consequences are inevitable (such as too much thyroid hormone or too much cortisol). Remember that the nervous system and endocrine system act together to signal and maintain homeostasis with the nervous system being very quick, producing almost immediate results, while the endocrine system is much slower, but its effects can last much longer. The reason the endocrine system is slower is because it is like driving the country roads to a destination through the winding, scenic routes of the bloodstream rather than the direct 401, no fooling around pathway down a neuron.
