Just under the surface of your skin are various sensors detecting different conditions - pressure and temperature are just two (which is how you can tell if something is hot to the touch, or if you are pressing a button). A third type of sensor is made out of nerve endings which, if damaged send a message to the brain that we interpret as 'pain'. Therefore, if you cut your finger, for example, you will damage these nerve endings and therefore feel pain. In your hair and nails, there are no such sensors, so you can cut these without feeling any pain. Pain is important. By your body being able to tell you that a part of your skin is damaged through something as alerting as pain, this will alert you to the problem. A simple cut is not a big problem, but if you did not realise that you had damaged your skin because of pain then you might not treat it until you actually noticed it much later. This might result in blood loss, or, more importantly in a small cut where blood loss was minimal, it might result in infection getting in and causing a small cut to become a much more serious problem. So, next time you cut a finger, be thankful that you can actually feel the pain - this is your bodies' way of telling you something is wrong and that you need to attend to it.

What layer of dermis is below the epidermis?
The Papillary Layer which is a part of the Dermis
What layer of skin has nerves and blood vessels?
Also known as the subcutaneous layer or the sub-dermis. It is called Submucosa.
What is the superficial region of the dermis?

What are the two layer of the dermis?

Why do paper cuts don't bleed a lot but always hurt a lot?
The reason paper cuts don't usually bleed is because it doesn't cut down into the skin deep enough, but still deep enough to slice the nerves. Paper cuts are so microscopic, they are able to cut into the Epidermis, the outer layer of skin, where nerves are located. The paper cuts the nerve ending, which is the reason for the extreme pain. The paper, however, is not able to cut further into the skin, the Dermis, where the blood is.
What happens when the epidermis and the dermis are destroyed?
difference between an antibody and an antigen
