Researchers found a separate sensory system in blood vessels and sweat glands that also allows abilities such as touch and feel. This lead scientists to understand that the sensory system of humans is far more complex. The story begins with two patients who lead normal lives went to a doctor to find out about their excessive sweating. It was then that the doctors found out that their responses to certain tests were off and that their senses were impaired. When they looked at their skin, they found that they had no typical nerve endings but the two patients were still able to sense things. This lead them to find that the nerve endings on the blood vessels and the sweat glands allowed them to feel. So in the end, besides the nerves that are on our skin, their are also nerve endings on blood vessels and sweat glands embedded in the skin that give humans the ability sense different things.
