What else can I help you with?
Are nails alive?
... No. It's dead skin cells.
What protects the ends of fingers and toes?
Fingernails and toenails are plates of stratified squamous epithelial cells with hard keratin that protect the distal ends of the phalanges. The phalanges are the finger bones.You are describing finger nails and toe nails. For some interesting nail facts: fingernails grow faster than toenails. The fingernails on the right hand of a right-handed person grow faster than those on their left hand.
Do fingernails and toenails have the same DNA?
Yes, all the parts of the same body have identical DNA (with the exception of very rare people known as chimeras, formed when the embryos of fraternal twins merge and the cells of what would have been two different persons intermingle in the body of one person). However the cells that make up fingernails and toenails are dead and there may be some degradation of their DNA.
Can fingernails breathe?
Finger and toenails are dead cells and do not need to breathe. However, they will dry out, especially with the use of acetone and other chemicals used to strip polish. Using a jojoba treatment in between manicures will help with the dry, brittle feeling. Cleanliness is also very important for good nail health.
What is cell specialized in a multicellular organism?
When each cell specializes in a certain task: some cells make fingernails, others become blood cells, brain cells, kidney cells, etc.
How does toenails grow back?
Toenails grow back from the nail matrix, which is located under the base of the nail, just behind the cuticle. As new cells are produced in the matrix, they push older cells forward, resulting in the visible growth of the nail. The process can take several months, with toenails typically growing back slower than fingernails, depending on factors such as age and overall health. If the nail matrix is damaged, it may affect the shape or growth of the new nail.
What structure in the human body does not contain blood vessels?
The point of a blood vessel is to transport blood throughout the body in order to distribute nutrients and wick away cellular waste. The only living cells in the body that aren't directly served by blood vessels are the cells in the eye's cornea; rather than obtain their nutrients through blood, these cells receive all needed nutrients through diffusion across the aqueous humour (the watery substance between the lens and the cornea). Other body parts that don't have blood vessels include hair, nails, enamel, and outer skin layers.
What are whole blood cells?
There little blood cells kinda like white blood cells but there like your stoner blood cells and they just kinda chill around and don't really do anything
Is anything in your blood magnetic?
The iron in the hemoglobin of red blood cells
Does the heart carry anything besides blood?
The heart does not actually carry anything, it only pumps blood. The blood however, carries nutrients and oxygen to body cells and wastes away from the cells.
Does the size of red blood cells have anything to do with determining a persons blood type?
The size of blood cells is not a factor in determining a person's blood type. Blood type is determined by a combination of certain proteins in the cells.
How do toenails and fingernails grow?
Nails grow from an area of rapidly dividing cells known as the nail root. The nail root is located at the tips of fingers and toes. During cell division, the cells of the nail root fill with keratin and produce a tough, platelike nail that covers and protects the tips of fingers and toes.
