In reality: Yes, you probably can devour a finger, but it's not comparable to chomping on a vegetable, and gnawing on your own digit would require a substantial commitment to searing pain.
Could you bite your own finger off, if you really wanted to? At the knuckle, possibly, but it would be very difficult. A 2012 study of hand injuries from electric windows in cars found that an average of 1,485 Newtons of force was required just to fracture a human finger.
Human bites usually cause only bruises and shallow cuts. However, if someone bites a small part, such as your ear, nose, finger, or penis, they can bite it off.
There are cases of fingers being bitten entirely off, but such an act requires extraordinary force, far greater than 200 newtons of carrot-cutting power. You'll still have to bite through skin, tendons, and some flesh.
Amazingly, platinum, iron, copper, tin and lead all rank below Apatite in hardness. I would rank these materials as among the hardest things teeth could scratch or otherwise damage.
What is the bite force of a human? Although we have a bite force stronger than some of our other primate relatives, the average human bite force is 162psi.
Human bites can be as dangerous as or even more dangerous than animal bites because of the types of bacteria and viruses contained in the human mouth. Human bites that break the skin can become infected.
Did you know that the human jaw is capable of exerting up to 125 kg of force in a single bite? On average, the female bite registers at 50 kg, while the male bite registers at 70 kg.
The average human bite force is between 120-160 PSI (pounds per square inch). However, this pales in comparison to many wild animals, many of which use their teeth not only to chew, but also to grip and tear.
A person with dermatophagia compulsively bites, gnaws, or eats their skin. This might leave their skin raw. This damage to the skin can also increase the risk of developing a skin infection.
However, uncooked mammalian cortical bone is extremely resilient. The limiting factor is that the human jawbone is made of uncooked mammalian cortical bone: clearly the human jawbone cannot bite through a thicker bone than itself, because it would break itself first.
A previous study reported that the mean bite strength for men is about 304.9 N, and 284.9 N for women, 32 whereas the mean bite strength of a patient with a parafunctional nocturnal clenching and gnashing habit is 795.7 N.
Your wound may heal in less than a week, or it may take longer, depending on how bad it is. The larger it is, the longer it will take to heal. The doctor has checked you carefully, but problems can develop later. If you notice any problems or new symptoms, get medical treatment right away.
No. The finger has a bone in it that the carrot lacks so it is much more difficult to do. You could bite at the joint which would be easier but tendons are fat tougher than a carrot. Also biting a carrot does not hurt you in any way.
A gnathodynamometer (or occlusometer) is an instrument for measuring the force exerted in closing the mouth. This device can measure the bite force of humans in the following three measurements: newtons, (N), pounds, (lb), or kilograms, (kg). The average bite force of a human being is 126 pounds per square inch, (psi).
To give you a comparison, humans have an average bite force of 120-140 psi, and the Nile Crocodile has a bite force of 5,000 psi. The bite force of average dogs ranges somewhere around 230-250 psi, but some have more strength.
Have you ever wondered why humans have such weak bites compared to other animals? While some animals, like alligators and lions, can chomp down with over 1,000 pounds of force, the average human bite force is only around 200–300 pounds of force.
Bull Shark (478 psi)
Bull sharks have the strongest bite of any shark when you factor in body size. They're much smaller than white sharks, reaching typical sizes of nine feet and around 800 pounds. White sharks of a similar size would only be capable of around 360 PSI.
The jaw muscles attach to the skull and inflict stress upon it when they work. But our jaw muscles can produce a strong bite through less effort than those of other primates. As such, they inflict fewer stresses upon the skull, which can afford to abandon some of its sturdiness.
Finally, is the king which is pushing bite force to extremes. At #1 we have Nile Crocodiles with a whopping 5,000 PSI bite. A person's bite strength clocks in on average at just 162 PSI which means the supreme force of Nile Crocodiles is 30 times stronger than ours!
Human bites are often more dangerous than animal bites because the human mouth has more bacteria in it than most animals' mouths. It is very easy for a human bite to become infected. However, any bite that breaks the skin can become infected and should be treated by your healthcare provider.
Pain, bleeding, numbness and tingling may occur with any human bite. Symptoms from bites may be mild to severe, including: Breaks or major cuts in the skin, with or without bleeding. Bruising (discoloration of the skin)
Can you die from a human bite? It's unlikely that a human bite will be fatal, especially if you seek proper medical care. However, human bite wounds can be dangerous, largely due to the many types of bacteria transmitted through human saliva.
7 -- Pressure, in PSI, that a swimmer feels at the bottom of a 16-foot-deep pool. 60-70 -- Water pressure, in PSI, of a typical municipal water system. 70 -- Pressure, in PSI, of the typical human jaw chewing food. More than 700 -- Pressure, in PSI, at which a human can grind his or her teeth at night.
