Receptors allow hormones to bind to their target cells.
steroid hormones are hydrophobic and bind to transport proteins which bind to receptors within the nucleus. hydrophillic hormones bind to plasma membrane receptors and act through second messenger systems
Water-soluble hormones. Insulin and epinephrine
This is because they do not have the ability to pass through the membrane, unlike steroid hormones. Steroid hormones bind inside the cell cytoplasm before docking onto the receptors.

growth factor hormones such as insulin bind to which type of rector
steriod hormones - since they are lipophilic and fusses with the membrane to enter teh cell.
Channel linked receptors bind to neurotransmitters. (also called ion channels and ligand gated ion channels) A ligand is the signal molecule i.e the neurotransmitter. Hormones bind to intracellular receptors because hormones are non polar and can cross the cell's plasma membrane. (also called cytoplasmic receptors)
Hormones do not bind to receptors with high capacity. The major defining properties of a hormone-receptor interaction, and what determines the strength of response is binding affinity and efficacy.
preganglionic sympathetic fibers releasing acetylcholine that bind to receptors on the adrenal medulla
Chlorine can bind with the same receptors as iodine, blocking the production of thyroid hormones in the thyroid gland.
