What is the longest axon in the human body?
sciatic nerveThe longest axons of the human body are those that make up the sciatic nerve where the length can exceed one meter..
What body type lives the longest?
When it comes to body shape and longevity, it’s more helpful to compare apples and pears. That’s the message of a study published in the journal PLOS ONE that found that pear-shaped people, who have comparatively thinner waists than people shaped like apples, tend to live longer.
What is RBC lifespan?
Human red blood cells are formed mainly in the bone marrow and are believed to have an average life span of approximately 120 days.
What is the longest nerve cell in humans where is it and how long is it?
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).
Which is the second largest cell in human body?
Largest one is NERVE CELL.Second largest is OVUM/EGG.Longest cell is NERVE CELL.Smallest one is Granule Cell of the Cerebellum (remember in context of volume sperm is)World’s smallest cell is PPLO( Mycoplasma)World’s largest cell is Ostrich eggs.
Where is the longest neuron in the body?
The longest neuron in the human body extends from the lumbar and sacral plexuses in the lower area of the spinal cord to the toes.
What is the lifespan of cell?
Skin cells live about two or three weeks. Colon cells have it rough: They die off after about four days. Sperm cells have a life span of only about three days, while brain cells typically last an entire lifetime (neurons in the cerebral cortex, for example, are not replaced when they die).
How long is a human body designed to live?
400 years”The human body is designed to live for 400 years, but we torture our bodies through excesses of food and lifestyle. We invite high blood pressure, heart ailments and other diseases that lessen its life span and makes it depend on doctors and medicines for the rest of our lives,” Ramdev said.
Which WBC has maximum life span?
Although lymphocytes have maximum life span among WBCS. But out of the given options, monocytes have a maximum life span which can be hours to days.
Which is the smallest cell in the world?
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.
How old is the oldest cell in your body?

Which blood cell has the shortest lifespan?
Probably neutrophils (granulocytes) have the shortest lifespan of human cells, 4 hours or less.Neutrophils make up about 55–70% of our white blood cells. … Because of the short lifespan, they need to be made continuously.More items…
What food increases white blood cells?
Vitamin C boosts white blood cells to fight infection, while kiwi’s other nutrients keep the rest of your body functioning properly. When you’re sick, chicken soup is more than just a feel-good food with a placebo effect….Popular citrus fruits include:grapefruit.oranges.tangerines.lemons.limes.clementines.
Which cell is the longest?
nerve cellThe longest cell is the nerve cell. The largest cell in the human body is female ovum.
How long is the longest nerve in the human body?
Some may be quite small while others may be up to one meter long . Similarly, nerves can vary in size as well. As your PNS branches out, your nerves tend to get smaller. The sciatic nerve is the largest nerve in your body.
