Snakes have the ability to detect the temperature through their skin. There are professors in mechanical engineering that are regularly working on artificial skin materials that can easily sense temperature through different ways. It is exactly similar to the snake that helps in proving various areas in the medical field.
By using protein channels, snakes can see in the dark by activating heat from the bodies of the prey. Pythons, vipers and boas contain holes on their faces that is known as pit organs. It contains a special kind of membrane that helps in detecting infrared radiation coming from the warm bodies. But during night time, the pit organs allow the snakes so that they can see the image of their predator or prey. This function is similar to the infrared cameras that help in providing unique and extra sense.
A study have been conducted which shows the method of revealing the work that is done at molecular level. Nerve cells are present in pit organs that contain an ion channel known as TRPA1. It is known as an infrared receptor that helps to detect infrared radiation in the form of heat and allow different theories of pit-organ function to hold behavioral ecologists. These receptors are found inside the head of the mammals that also contains TRPA1 channels. They are known as wasabi receptors. They can detect pungent irritants that can be extracted from mustard plants or various other sources.
There are animal physiologists that work in a better manner on the anatomy of the sensory system of animals, as it is very important. The pit organs also contain nerve fibers that are known as trigeminal ganglia. The molecular organ can detect heat by making comparison with trigeminal ganglia along with dorsal root ganglia.
The latter supply of the brain with sensory input from the lower part of the neck can easily produce proteins with pit-organs that is essential for the detection of the heat. By using different kinds of produced RNAs have each type of nerve that indicates which gene is active and are producing proteins. But they are expressed differently in two-different kinds of ganglia with the gene in the trigeminal ganglia. It also produces RNA 400 times of dorsal root ganglia.
