Cells which have only one copy of the chromosome are termed as haploid cells. For example, the sex cells of the humans i.e egg cell and sperm cells comprise of 23 chromosomes. This is half the number of chromosomes than the autosomal cells.

In its upper part (near the entrance of the superior vena cava) is located the sinus node, microscopic structure from which the electrical impulse which ensures the contraction of the heart (especially atrium) ...
