What is the longest nerve cell?

The longest axons in the human body are those of the sciatic nerve, which run from the base of the spinal cord to the big toe of each foot.

The diameter of axons is also variable.

Most individual axons are microscopic in diameter (typically about one micrometer (µm) across)..

What is the biggest cell in the female human body?

Which is the largest cell in animal?

ostrich eggThe largest cell is an ostrich egg, it is about 15cm to 18 cm long and wide.

Which cell is smallest?

spermThe sperm is the smallest cell in human biology, but also one of the most complex. The egg meanwhile is the largest cell and similarly intricate. Looking further out into the natural world, the diversity of these sex cells, or gametes, is truly remarkable. Most species have two gametes, which we term male and female.
