The other two chromosomes, X and Y, are the sex chromosomes. This picture of the human chromosomes lined up in pairs is called a karyotype. In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.
All the cells in the human body, including the nerve cells, have 46 chromosomes (23 pairs) (except the sperms and egg cells, which have 23 chromosomes each).umans have 46 chromosomes in their nerve cells, unless they have a  chromosomal disorder. With the exception of the reproductive cells,  which only carry half the chromosom â¦ al DNA, all human cells have the  same amount of chromosomes.
