Did You Know? The Surprising Strength of Human Jaw Muscles

Taking the cue from fellow member M. Peer Mohamed Sardhar, let me share some information and facts I have come across.

Human jaw muscles can generate a force of 200 pounds (90.8 kilograms) on the molars.

Thank you.

A large swarm of desert locusts (Schistocerca gregaria) can consume 20,000 tons (18,160,000 kilograms) of vegetation a day.

The largest flying animal was the pterosaur, which lived 70 million years ago. This reptile had a wingspan of 36-39 feet (11-11.9 meters) and weighed 190-250 pounds (86-113.5 kilograms).

Scientists have discovered that copper pollution of the atmosphere occurred about 2500 years ago. This was discovered by analyzing ice cores from Greenland. The pollution was attributed to the Romans who used copper for military purposes and to produce coins.

The highest temperature produced in a laboratory was 920,000,000 F (511,000,000 C) at the Tokamak Fusion Test Reactor in Princeton, NJ, USA.

The Stegosaurus dinosaur measured up to 30 feet (9.1 meters) long but had a brain the size of a walnut.

The largest telescope in the world is currently being constructed in northern Chile. The telescope will utilize four 26 ft. 8 in. (8.13 meters) mirrors, which will gather as much light as a single 52 ft. 6 in. (16 meters) mirror.

The longest cells in the human body are the motor neurons. They can be up to 4.5 feet (1.37 meters) long and run from the lower spinal cord to the big toe.

40 to 50 percent of body heat can be lost through the head (no hat) as a result of its extensive circulatory network.
