Cell Signalling and Transduction
The signaling molecules called steroid hormones

bind to cell surface receptors to trigger chemical cascades

are made in one location of the body but have their effects some distance away

never enter the blood of humans

are hydrophilic and so cannot penetrate the plasma membrane
