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.
Which is the longest cell in the world?
Answer. Answer: If talking of human body, largest cell is OVUM or egg cell owing to its diameter however nerve cells are the longest cell. And all over the world the largest and longest cell are the NERVE CELLS Giant Squid and Colossal Squid.
What is the smallest cell in the human body?
The 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.
What is the largest 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 main nerve in your body?
The sciatic nerve is the largest and longest spinal nerve in the human body. Extending from the lumbar and sacral plexuses in the lower back, the sciatic nerve runs through the buttocks and into the thighs. It delivers nerve signals to and from the muscles and skin of the thighs, lower legs and feet.
Which is the largest cell in human body?
The human egg (ovum) is the largest cell in the body and a nerve cell is the longest cell in the human body. The sperm is the smallest cell in human biology, but also one of the most complex.
What are the 4 types of nerves?
What are the types of nerves in the body?
- Autonomic nerves. These nerves control the involuntary or partially voluntary activities of your body, including heart rate, blood pressure, digestion, and temperature regulation.
- Motor nerves. …

Which is biggest animal cell?
Caulerpa taxifolia is the largest animal cell. it is an aquatic alga. Largest animal cell is ostrich eggs measuring about 170*135 mm in diameter.
Who discovered cell?
Initially discovered by Robert Hooke in 1665, the cell has a rich and interesting history that has ultimately given way to many of today’s scientific advancements.
Which is the longest animal cell?
Complete answer: Neuron also known as a nerve cell is a cell that is the longest cell of animals which has the capability to get excited by electrical or chemical impulse.
What is the smallest cell in the female body?
The ovum also called egg cell is the reproductive cell in the female body. Granule Cellof the Cerebellum is the smallest cell of the human body which is approximately 4 micrometer to 4.5 micrometer in size.
What is the biggest cell in the female human body?
The ovum is one of the largest cells in the human body, typically visible to the naked eye without the aid of a microscope or other magnification device. The human ovum measures approximately 0.1 mm (0.0039 in) in diameter.
