Finally, vision involves the activation of photoreceptors. They are found in both glabrous and hairy skin. Oval window. Neurons are not physically connected, but communicate via neurotransmitters secreted into synapses or gaps between communicating neurons. For this reason, capsaicin can be used as a topical analgesic, such as in products like Icy Hot. Deeper in the epidermis, near the base, are Ruffini endings, which are also known as bulbous corpuscles.

It is not surprising, then, that humans detect cold stimuli before they detect warm stimuli. Buds We tend to classify receptors according to the location or origin of the stimulus: Exteroceptorsrespond to stimuli from outside the body - vision, sound, touch, smell, temperature, pain etc. This table shows that there are five basic types of sensory receptors: (1) mechanorecep-tors, which detect mechanical compression or stretching of the receptor or of tissues adjacent to the receptor; (2) thermoreceptors, which detect changes in temperature, some receptors detecting cold and others warmth; (3) nociceptors (pain receptors), which 3.
