You will be assigned a set of hormones for which you must determine the gland that secretes it, the target cell(s) of the hormone, and the function/mechanism of action of the hormone.

Mechanism of action (How does it work?) Discussion: Each member of your jigsaw group will present their findings. It is your responsibility to fill in the following table for all hormones discussed (13 in total). Gland Hormone Target Cell Function How is it controlled
