Neurons and Nerves
Neurons are unique for many reasons. For one, they have a shape that is not like any other cells. Nerve cells are also some of the longest cells in your body. There are nerve cells as long as a meter. They stretch from your hips all the way down to your toes! This is very uncommon for cells, which are usually very short. Most cells are 20 micrometers in diameter, which is just a fraction of the width of a hair.
