receptor

/rɪˈsɛptə

1An organ or cell able to respond to light, heat, or other external stimulus and transmit a signal to a sensory nerve: the retina of the octopus has up to 20 million light receptors...

In the special sense organs, such as the eye and the ear, highly specialized receptors respond to light and sound.
Our own skin contains a battery of touch receptors that produce nerve signals when pressed.
However, they have some ability to sense light through receptors in the epidermis.

1.1A region of tissue, or a molecule in a cell membrane, which responds specifically to a particular neurotransmitter, hormone, antigen, or other substance: when viruses succeed in binding to cell membrane receptors they still have to enter the cell before they can replicate...

When the neurotransmitter binds with the receptor, the next cell responds accordingly.
Hormones work by docking with a specific receptor on a cell, which then responds by turning on genes.
Finally, the presence of a specific receptor in the target tissue is required for a hormone to have its effect.

Origin

Early 20th century: coined in German from Latin receptor, from recept- 'taken back', from the verb recipere (see receive).
