These channels are known as ‘ligand-gated’ because it is receptor binding that operates them (in contrast to ‘voltage-gated’ channels that respond to changes in membrane potential) (see B in figure). http://www.pharmacologyeducation.org/overview-types-receptors-their-mechanisms-action-and-examples harbor house block island
