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.

the epidermis and the dermis
Has the cut penetrated into the dermis or epidermis if you are not bleeding?
If there is no bleeding, the cut has likely not penetrated into the dermis, as the dermis contains blood vessels that would typically bleed when injured. It is more likely that the cut is limited to the epidermis, the outermost layer of skin. However, some deeper abrasions or injuries may not bleed if they are superficial and do not damage the blood vessels. A thorough examination is needed to determine the depth of the injury.
If you get a cut in the epidermis will it bleed?
If you would get a cut in the epidermis it wouldn't bleed because the cells in the stratum basale can easily divide and repair the damage...Now if you would get a cut in the dermis it would bleed because it doesn't have the under layer to protect it and repair it..
