There are two types of hormones secreted in the endocrine system: Steroidal and non-steroidal, (or protein based) hormones. The endocrine system regulates its hormones through negative feedback, except in very specific cases like childbirth.
This Osmosis High-Yield Note provides an overview of Anatomy and Physiology of the Endocrine System essentials. All Osmosis Notes are clearly laid-out and contain striking images, tables, and diagrams to help visual learners understand complex topics quickly and efficiently.
Explain how the different glands work together to maintain homeostasis. The endocrine system produces hormones that function to control and regulate many different body processes. The endocrine system coordinates with the nervous system to control the functions of the other organ systems.
o Two classes of hypothalamic regulatory hormones 1. Releasing hormones (RH) o Stimulate synthesis and secretion of one or more hormones at anterior lobe 2. Inhibiting hormones (IH) o Prevent synthesis and secretion of hormones from the anterior lobe o Rate of secretion is controlled by negative feedback 18-3 The Pituitary Gland
composed of a group of glands placed throughout the body, releases chemicals (hormones) that must travel through the circulatory system to reach a target tissue or organ causing that tissue or organ to effect a regulatory change.
The nervous system controls homeostasis through nerve impulses and neurotransmitters, which act locally and quickly. The endocrine system uses hormones, which act more slowly in distant parts of the body. The nervous system controls neurons, muscle cells, and glandular cells.
Endocrine glands are special groups of cells that make hormones. The major endocrine glands are: Vital to our overall health, hormone levels change as we grow and age.
