Nonsteroid hormones such as epinephrine and insulin bind to specific receptors on the cell membrane and require a second messenger, such as cyclic AMP or calcium ions, to transmit the signal within the cell. Steroid hormones, on the other hand, can directly enter the cell and bind to intracellular receptors in the nucleus.
