Question

Quizplus · Accepted Answer

The reticular activating system is responsible for regulating a person's level of arousal and alertness. It is located in the brainstem and receives input from various sensory systems. Injuries or damage to this area can result in changes in consciousness, from lethargy to coma. The renin-angiotensin-aldosterone system regulates blood pressure and fluid balance, the cranial nerves are responsible for various functions such as facial expression and sensation, and the adrenal glands produce hormones such as adrenaline and cortisol. However, none of these are directly responsible for a person's level of arousal or alertness.
