Brain cells of the cerebral cortex (the grey matter) are with you from birth.
46 in a human body cell. 23 in the sex cell e.g. sperm and egg cell (gametes) when they combine you end up with 46 again.
A normal human cell contains 23 pairs of chromosomes, for a total of 46. If you had an average of 40 trillion cells in your body that had 412 chromosomes you would have 4456 trillion chromosomes in your body. Note that some mature cells in your body do not have any chromosomes, some have 26 chromosomes and some cells have 99 chromosomes.
Cell walls are not found in human cells. Instead, human cells are surrounded by a cell membrane, also known as the plasma membrane, which helps control the movement of substances in and out of the cell.

The average cell diameter in the human body is about 10-20 micrometers, which is equivalent to 10,000-20,000 nanometers.

There are a number of contenders for the position of smallest cell in the human body. The head of the sperm is on average 5 to 6 micro meters. The flagellum is up to 50 micrometers long. Also some says Granule Cell of the Cerebellum is the smallest cell of the human body it is approximately 4um to 4.5um in size. The size of the RBC also found as around 5 micrometers. In terms of volume most of the scientists suggest that sperm is the smallest cell.
Nerve cell is the longest cell in human body.
The Longest cell in the human body is the nerve cell.
Many sources say that the average human has 100 trillion cells in their body. So, one cell would be 1/100 trillionth of your entire body. I've also heard that the average cell contains 100 trillion atoms. That means your body contains roughly 10,000,000,000,000,000,000,000,000,000 atoms.
Simply a "Cell", in general, anyway... Eukaryotic cell is the name for a regular human body cell.
how are cells alike a human body
* well it depends on what can of cell i know that it is a animal cell but not every body cell is not the same size. * well it depends on what can of cell i know that it is a animal cell but not every body cell is not the same size.

Red blood cells, also known as erythrocytes, lack a cell nucleus in the human body.
