Human fingernails are essentially made up of the same long fibers that human hair is made of; it is a protein called keratin. This substance is also the primary structural component of horns and hooves on animals. Keratin is a protein that has no color and in the hair, there are two types not solely the exact element found in fingernails. The actual fingernail originates at the base of the nail from what is known as a growth plate. The growth plate or cuticle is the area where the skin of the finger connects to the nail.

The fingernail is formed from the cells located in the growth plate called the epithelial cells. There are three types of epithelial cells: squamous, cuboidal, and columnar. As these cells age they are pushed outward by newly generated epithelial cells at the base of the nail in the growth plate. These cells that have been pushed forward, in the never-ending process, eventually die, allowing the inside of the cell to be taken over by the hard protein keratin which is why our fingernails are so hard and constantly growing.

Your fingernails are made of a substance called keratin which is an extremely hard protein. This same substance is also found in hair, skin, hooves, horns and teeth.

Your finger nails and toe nails are made of the same stuff as your hair. Your hair is made up of extra body waste. Have you ever noticed that the nails on the hand you write with grow faster then the hand you don't. Also, on the foot that is opposite of the hand you write with the nails grow faster then on the other foot

I've heard that your nails are made out of dead worms is this true? And I've also heard that the gross brown/black stuff under your nails is fecal matter and dirt, is that true?
