In class today we continued our discussion on Ch. 50, The Endocrine System.
We began the discussion with the slide on what happens when hormones are no longer needed.
Below are  charts, diagrams, and questions that are going to be useful to take a look at for the final.
This chart is displaying the three types of hormones.
Also, there is a table in your Biology textbooks, table 50.2 that shows the hormones involved in the hypothalamus of the brain and the anterior pituitary. To remember these hormones use FLAT PEG. In the FLAT portion, the F stands for the Follicle-stimulating hormone (FSH), L is the Luteinizing hormone (LH), A is the Adrenocorticotropic hormone (ACTH) and T is the Thyroid-stimulating hormone (TSH). For the PEG portion, the P stands for Prolactin (PRL) the E does not represent anything and the G is the Growth hormone (GH).
The chart below is showing the hormones that are important for METABOLISM and ENERGY BALANCE.

This chart was also on Dr. Hartley's slide show.
