Different types of receptors detect various kinds of energy from the environment. Here are a few examples:

 Photoreceptors capture photons of light.

 Auditory hair cells respond to acoustic energy, or sounds.

 Mechanoreceptors are located in the skin and respond to touch.

 Olfactory and taste receptors respond to molecules interacting with receptors in our noses and tongues.

Neurons also respond to each other via receptors for various neurotransmitters. Some neurons respond to hormones circulating in the extracellular space or bloodstream. Also, specific neural responses to extracellular ion concentrations can occur.
