Your question: Which is the longest nerve cell in human body?

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).

Is nerve cell the longest cell?

– In the human body, the nerve cell is the longest cell. Nerve cells are also called neurons that are found in the nervous system.

What is the length of nerve cell in human body?

Think about how long the axon of a motor neuron would be if you wanted to make a model of it. The cell body of a motor neuron is approximately 100 microns (0.1 millimeter) in diameter and as you now know, the axon is about 1 meter (1,000 millimeter) in length.
