Several species of fish, sharks , and rays have the capacity to sense changes in electric fields in their immediate vicinity. Her writing is featured in Kaplan AP Biology Rods also give humans vision when there is limited light available, like at night.
A dolphin can detect electric fields in water using electroreceptors in vibrissal crypts arrayed in pairs on its snout and which evolved from whisker motion sensors. People with synesthesia can see sounds as colors or associate certain sights with smells, for example.
There are also receptors for pain, known as nociceptors, and for temperature, called thermoreceptors. The only orders of mammals that are known to demonstrate electroception are the dolphin and monotreme orders.

Sound is funneled through the external ear and piped into the external auditory canal. The transparent outer layer of the eye called the cornea bends the light that passes through the hole of the pupil.
The smell receptors react with the molecules of these fumes and then send these messages to the brain. Not everyone is able to use all five of their senses.
Five sense organs and their functions
The brain then interprets and one is able to know whether it is hot or cold and or when in pain or friction. In reptiles the vomeronasal organ is commonly referred to as Jacobsons organ. They do this with the olfactory cleft, which is found on the roof of the nasal cavity, next to the "smelling" part of the brain, the olfactory bulb and fossa. Experimenters were able to arrange for subjects to perceive certain "forced stops" as if they were their own choice. Top 10 facts There are five senses — sight, smell, touch, taste and hearing. The Rutgers study backs up a previous study at the Rockefeller University in New York, whose findings were published in the March issue of the journal Science. Continue Reading. Our sense of smell is capable of identifying seven types of sensations. Pit vipers , pythons and some boas have organs that allow them to detect infrared light, such that these snakes are able to sense the body heat of their prey. The retina is covered with two types of light sensitive cells — the cones and the rods. And the chips in your chocolate chip cookie could be a combination of sweet and bitter.
