Webfertilization. Generally speaking, hormones change gene expression or cellular function, and affect behavior by increasing the likelihood that specific behaviors occur in the presence of precise stimuli. Hormones achieve this by affecting individuals’ sensory systems, central integrators, and/or peripherial effectors. To gain a full understanding WebSome cells simply lack the ability to “see” the hormone and do not respond to its presence. Competency to perceive a hormone depends on a cell’s physiology when the hormone is present.
