In the light, we see colors with receptors called cones.

Drugs, like hormones, act on special switching sites in the body called receptors.

The switches, large proteins called receptors, are usually found on a cell's surface.

They are made up of thousands of little receptors called ommatidia.

In the dark, you see in shades of gray using receptors called rods.

Electromagnetic waves, commonly known as light, hit specialized nerve cells, called receptors, in the human eye.

Called receptors, the proteins pick up messages received from hormones and generate a corresponding signal inside the cell.

Rimbonant largely works by blocking a receptor called CB1.

It uses receptors called neuromasts, each of which is composed of a group of hair cells.

When these sites, called receptors, are occupied by tamoxifen, estrogen cannot hook on properly and exert its usual effects.
