Chapter 16/17 Anat 2 Test

Describe the roles of endocrine glands within the endocrine system.

release chemical messengers called hormones directly into the bloodstream to regulate vital bodily functions and maintain internal balance

Define the term hormone.

chemical messengers released by glands that travel through the blood to tell your organs and tissues what to do and when to do it

Explain the relationship between receptors, hormones, and target cells.

Hormones act as chemical messengers that travel through the bloodstream, but they only affect specific target cells that have matching receptors

Explain the similarities and differences between the endocrine system and nervous systems.

The nervous and endocrine systems are both essential for maintaining homeostasis in the human body. While they share some similarities, such as their involvement in regulating physiological functions and their connection to the hypothalamus, they have significant differences. The nervous system transmits signals electrically and chemically via neurotransmitters and has a rapid response time with short-lived effects. In contrast, the endocrine system transmits signals through hormones in the bloodstream, with a slower response time and longer-lasting effects. Additionally, the nervous system has specific target cells, while the endocrine system often affects multiple tissues or cells.
