How Hormones Work
Hormones are chemical messengers that relay messages to cells that display specific receptors for each hormone and respond to the signal.

Intracellular Hormone Receptors
Lipid-soluble hormones diffuse across the plasma membrane of cells, binding to receptors inside the cells where they alter gene expression.

Plasma Membrane Hormone Receptors
Hormones that cannot diffuse through the plasma membrane instead bind to receptors on the cell surface, triggering intracellular events.
