Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is a difference between Nervous & Endocrine System regulation?
A
rely on release of chemicals that bind receptors on target cells
B
length of time of action
C
negative feedback mechanisms
D
homeostasis
Explanation: 

Detailed explanation-1: -Responses to nervous system stimulation are typically quick but short lived. The endocrine system responds to stimulation by secreting hormones into the circulatory system that travel to the target tissue. Responses to endocrine system stimulation are typically slow but long lasting.

Detailed explanation-2: -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-3: -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-4: -The action of the endocrine system is measured in minutes, hours, or weeks and is more generalized than the action of the nervous system.

Detailed explanation-5: -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 1).
