Final answer:
Information is transferred in the nervous system using nerve cells and chemical signals, specifically from the "endocrine" system, which uses hormones to communicate and maintain homeostasis.
Step-by-step explanation:
In the nervous system, information travels through nerve cells, and other messages are sent by chemical signals that are produced in the endocrine system. This system utilizes hormones to communicate throughout the body, making it one of the two major control systems alongside the nervous system. The nervous system relies on electrical impulses and localized chemical neurotransmitters to quickly send signals within milliseconds for immediate responses, such as reflex actions or sensory processing. In contrast, the endocrine system's hormones travel through the bloodstream over a longer period, allowing for a broader and more prolonged effect, which is crucial for maintaining homeostasis in the body. For example, during a fight-or-flight response, adrenal hormones like epinephrine and norepinephrine are released within seconds, while other hormones may take longer to elicit a response.
