No, eggcell is not the biggest cell in the human body
The Ovum or the “Egg” is the largest cell of the human body.The human egg is a giant compared to other cells in the body. It has a diameter of about 100 microns (millionths of a meter), or roughly the thickness of a strand of hair. No other cell in the body is anywhere near that. It is quite big for a cell because it can be seen barely with the naked eye whereas most other cells must be seen through a microscope.
Sometimes the Neuron is mistaken to be the largest cell because of its extensive role in the nervous system throughout the body. It is not the largest though it is the longest cell in the human body.
