Both the endocrine and nervous system are major regulating systems of the body however the nervous system has been compared to a text message and the endocrine system to mailing a letter. Briefly explain this comparison.

The nervous system produces rapid responses while the endocrine system generates slow but long term responses.

Explanation:

The nervous system rapidly generates a response by sending the sensory and motor information in the form of nerve impulses. The rapid responses of the nervous system are compared with text messages that are delivered instantly to the other person.

On the other hand, the endocrine system produces a relatively slow response by releasing hormones. Therefore, it is compared with a letter that takes a few days, depending on the distance, to be delivered to the other person. However, the effects of the endocrine system are long-lasting as compared to the short term responses generated by the nervous system.
