MICROANATOMY

Detailed explanation-1: -The signal transmission of the nervous system is fast because neurons are interconnected, but the functions are more short-lived. Signal transmission in the endocrine system is slow, since hormones must travel through the bloodstream, but the responses tend to last longer.

Detailed explanation-2: -In general, the nervous system involves quick responses to rapid changes in the external environment, and the endocrine system is usually slower acting-taking care of the internal environment of the body, maintaining homeostasis, and controlling reproduction (Table 14.1. 1).

Detailed explanation-3: -One of the most significant differences between the nervous system and endocrine system is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.

Detailed explanation-4: -The nervous system function at a much greater speed than the endocrine system. TRUE: The nervous system uses fast electrical impulses to carry a signal from one area to another, whereas the endocrine system relies on the relatively-slow blood circulation to take the signal to its destination.

Detailed explanation-5: -Does the nervous system or the endocrine system react faster to external/ internal stimuli? The nervous system reacts faster to external and internal stimuli.
