1. Daily Warm-up Monday, March 17th
What is a regulator? What is a conformer?
HW:
-Read 32.2
Turn in:
-Test corrections

2. Endocrine System Use of hormones and glands
Effects of a hormone can be long-lasting
Transmission of signals take much longer than nervous system
Well adapted for coordinating gradual changes that affect entire body
Growth, development, reproduction, metabolic processes, and digestion

4. Simple Endocrine Pathway
Endocrine cell receives stimulus and secretes a hormone
Hormone travels through blood system to target cell
Signal transduction within target cell produces response

6. Various Parts of the Endocrine System
Pituitary gland
Thyroid gland
Pancreas
Parathyroid gland
Adrenal gland
Reproductive glands
Ovaries
Testes

7. Neuroendocrine Pathways
Hormone pathways usually depend on sensor in nervous system
Hypothalamus integrates endocrine and nervous systems
Receives signals from nervous and sends them to pituitary gland

8. Positive Feedback Reinforces a stimulus
Do not play a major role in homeostasis but help drive processes to completion
Ex. Oxytocin production and lactation

9. Pathways of Hormones Lipid-soluble Water-soluble
Where are each located?
Signal transduction pathway
What does it end with?

10. Multiple Effects of Hormones
