A human somatic cell is a "body cell" (not one involved in sexual reproduction). Therefore, there are 46 chromosomes in a somatic cell. This is also the diploid number. Since we have two sets of chromosomes (one comes from mom and one from dad), we say algebraically that the diploid number = 2n = 46 (in humans). Therefore a haploid set = n = 23 in humans (this would apply to sperm and eggs).

I know of two kinds of cells that are not regenerated: Brain cells (neurons) and if you are female, eggs cells in the ovary.  The ones you are born with are still with you.

It's a bit of a philosophical question.  The number of moves is roughly 10^134 (ten to the power of 134).  Since the universe is basically infinite, and 10^134 is definately fininite, then nope it's not true.  \nAnother approach is to consider that there are roughly between 10^12 or 10^13 cells in every human on the planet.  Roughly 12 persons contain as many cells as there are moves in chess.  That *cells* not atoms.  Each cell can be millions of atoms, so as you can see chess moves are no where near the number of atoms in even a dozen human beings!

a somatic cell is any cell of the body except germ cells.[sex cells].thus a normal somatic cell has 46 chromosomes in it.

Current estimates of brain capacity range from 1 to 1000 terabytes! *terabyte is a 1000 gigabytes\n  \n"Robert Birge (Syracuse University) who studies the storage of data in\nproteins, estimated in 1996 that the memory capacity of the brain was\nbetween one and ten terabytes, with a most likely value of 3\nterabytes. Such estimates are generally based on counting neurons and\nassuming each neuron holds 1 bit. Bear in mind that the brain has\nbetter algorithms for compressing certain types of information than\ncomputers do."

On average, an adult human has 206 bones (according to Gray's Anatomy, but the number can vary slightly from individual to individual), but a baby is born with approximately 270. The difference comes from a number of small bones that fuse together during growth. They leave pockets of cartilage to allow more growth. The sacrum (the bone at the base of the spine) consists of six bones which are separated at birth but fuse together into a solid structure in later years. Growing is usually completed between ages 12 and 14. This means that the bones have no pockets of cartilage left, so there is no material left to allow more growth.

Stem cells originate from embryos which are a few days old. There are very strict guidelines regarding the harvest of stem cells, and they cannot be harvested from human beings beyond the embryo stage. They certainly do not come from the human brain.

On average, an ant has approximately 100,000 neurons in it's central ganglia.  It's interesting that you ask this, because ant colonies are commonly used to demonstrate the possible behavior of a 'dissociated brain" colony, in which the entire colony is a single organism.  A very large colony of ants could have as many as 1 billion neurons total...still many orders of magnitude less than a human, but pretty bright for an insect!

There are 206 bones in the body of a typical adult. However, babies have something like 315 when they're born, as the cartilege hasn't grown into its final shape yet.

A human parental cell (or germ cell) has 46 chromosomes or 23 pairs (2n).

The 10% myth is a myth, and has no scientific basis.  Please refer to the link.\n\nAs for your question, "brain storage" is not a quanitifiable notion because human brains are not digital.  You can easily count the digits in a digital computer storage device, but the simple truth is that the human brain does not resemble a digital storage device at all.  Besides that, I doubt that you could point at any person of any gender that maximized capacity, so capacity isn't even really an issue.  No one has learned so much that further learning bcomes impossible.  Computer discs fill up, but brains do not.

We do use our whole brain.  The statement "we only use 10% of our brain" is untrue.\nCheck out this site for more info:\nhttp://www.snopes.com/science/stats/10percnt.htm

In an average healthy adult, the volume of blood is about one-eleventh of the body weight. Most sources state the volume of blood in an average human adult, who is between 150 to 160 pounds, as between 4.7 and 5 liters, although the more recent sources state the volume of blood in an average adult as 4.7 liters. Sources state that an 80-pound child had about half that amount, and an 8-pound infant has about 8.5 ounces.In an average healthy adult, the volume of blood is about one-eleventh of the body weight.

it is actually depends on which cell we are looking at. most of your body cells except brian cells keep multiplying until a human reach the age of approx 18-19. your upper layer skin cells must be the first one to die approx. 24 hrs or so . your body shed the dead cells and new layers are keep coming from beneath.

The brain is not composed entirely of neurons.\n\nHere's some pertinent info:\n\nThe "cast of characters" (cell types) in the fully developed central nervous system (brain and spinal cord) is small: we have neurons, astrocytes, oligodendroglial cells, microglial cells, ependymal cells, blood vessel cells (endothelial cells) and a few remaining primitive (neuro)ectodermal cells. Any of these cells can become a tumor. Here they are: \n\nAstrocytes can become astrocytomas \n\nOligodendrocytes can become Oligodendrogliomas \n\nMicroglial cells can become a Microglioma which is now called a Primary nervous system lymphoma \n\nPrimitive ectodermal cells can become Primitive Neuroectodermal Tumors PNETs such as a Medulloblastoma \n\nEpendymal cells can become Ependymomas
