| 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. |
| But sharks also detect their prey with sensory receptors that run along their sides. |
| At this average receptor density, if all the particles are homogeneous, there are too few receptors on any particle to support any adhesion. |
| The saturation of receptors at a single central synapse by a quantum of neurotransmitter is the subject of much controversy. |
| The action of a common neurotransmitter, such as acetylcholine, illustrates how ion channel receptors work. |
