Full Answer

The skin of the fingertips is called glabrous skin, which does not contain hair and has more nerve endings, relays the Biology Encylopedia. Areas of the body with more hair have fewer nerve endings, causing them to be less sensitive. Skin on the fingertips also has a smaller receptor field, which is the size of the body surface that sends sensory input to a single neuron. The smaller the receptor field, the more sensitive the area.
