Fingernails
are just another type of skin, but not all nails are created
equal. The nails protect the nerve-rich fingertips and
tips of the toes from injury. Nails are a substructure
of the outer layer of the skin and are composed mainly
of keratin, a type of protein. Nails grow at the rate
of about 0.05 to 1.2 millimeters per week. The nail bed
is the skin on the top of which the nail grows. Healthy
nail beds are pink to dark pink, which show a rich blood
supply.
