Is The hyponychium is commonly called the cuticle?
false
What are the structures beneath the nails?
! Well, the part of the nail that we actually see is called the nail plate, and the skin is the cuticle. Beneath it is the nail bed and the matrix, and beneath those is the skin called the hyponychium. I don't know which three structures you actually need; I'm sure you could Google images 'the anatomy of a nail' and get a good diagram that could explain it better.
What are the three structure beneath the nail?
Nail StructureThe structure we know of as the nail is divided into six specific parts - the root, nail bed, nail plate, eponychium (cuticle), perionychium, and hyponychium. Each of these structures has a specific function, and if disrupted can result in an abnormal appearing fingernail.
What is a nail bed?
The nail bed is part of the nail matrix called the sterile matrix. It extends from the edge of the germinal matrix, or lunula, to the hyponychium. The nail bed contains the blood vessels, nerves, and melanocytes, or melanin-producing cells. As the nail is produced by the root, it streams down along the nail bed, which adds material to the undersurface of the nail making it thicker. It is important for normal nail growth that the nail bed be smooth. If it is not, the nail may split or develop grooves that can be cosmetically unappealing.
What are the nails in the human body made of?
Human nails are made of hard keratinized cells; keratin being a type of protein.
Of what material are finger nails made?
Keratin - the same substance that makes up hair.Anatomically fingernails and toenails, which are made of a tough protein called keratin and are produced from living skin cells in the fingers and toes, are made up of many different parts: * The free edge is the part of the nail that extends past the finger, beyond the nail plate. There are no nerve endings in the nail - this is the growing part of the nail still under the skin at the nail's proximal end. * eponychium or cuticle, is the fold of skin at the proximal end of the nail. * paronychium is the fold of skin on the sides of the nail. * hyponychium is the attachment between the skin of the finger or toe and the distal end of the nail. * nail plate is the hard and translucent portion, composed of keratin. * nail bed is the adherent connective tissue that underlies the nail, often colloquially referred to as the "quick." * lunula is the crescent shaped whitish area of the nail bed (when visible) * nail fold a fold of hard skin overlapping the base and sides of a fingernail or toenail. In common usage the word nail usually refers to the nail plate only
What is the scientific name for human nails?
Fingernails and toenails are made of a tough protein called keratin, as are animals' hooves and horns. Along with hair and teeth they are an appendage of the skin. The parts of the nail are: * Matrix This is the only living part of the nail. It is situated behind and underneath the Nail Fold and produces protein keratin which makes up the Nail Plate. If the matrix is ever damaged in any way, it would affect the Nail Plate growth. * Eponychium This is the dead skin that forms around the cuticle area. This can be lifted and trimmed during a professional manicure treatment. Tends to be more prominent on males. * Paronychium This is the 'live' skin that folds around the cuticle area giving protection to the Matrix. * Hyponychium, Is the area of attachment between the Nail Plate and Nail Bed that lies underneath the free edge. Anatomical terms of location Proximal and distal, end of the nail. * Nail plate Is the hard and translucent portion which is composed of layers of protein keratin. * Nail bed The Nail Bed is responsible for the 'pinkish' colour of the Nail Plate. It also determines what shape the nail will grow. * Lunula Tends to only be visible in larger nails. Is the whitish crescent shape around the base of the nail plate, is the shadow of the Matrix. * Nail fold A fold of hard skin overlapping the base and sides of a fingernail or toenail * Free edge The part of the nail that extends past the finger, beyond the nail plate. There should always be a free edge present to prevent infections. Ideally a free edge should be half of the 'pink' nail in length.[citation needed] * Nail Groove Acts as 'runners on drawers' and guides the direction of nail growth. They are situated down the sides of the Nail Fold.Taken from Wikipedia.com...the answer to all things.
