Can dopamine cause pain?
A diarthrodial joint is one in which the adjoining bone ends are covered with a thin cartilaginous sheet and joined by a joint capsule lined by a synovial membrane, which secretes synovial fluid. SYN: SEE: arthrosis (1) TYPES OF JOINTS.

The megalodon was a massive shark. The largest were roughly 60 feet in length and attained perhaps up to 50 tons, the size and weight of a railroad car. Female megalodons were, on average larger, at about 44 to 56 feet (13-17 m) and males were about 34 to 47 feet (10-14 m).

Megalodons are extinct. They died out about 3.5 million years ago. And scientists know this because, once again, they looked at the teeth. All sharks – including megalodons – produce and ultimately lose tens of thousands of teeth throughout their lives.

With a jaw estimated to measure about 9 x 11 feet, scientists have calculated that megalodon's bite force would be about 40,000 pounds per square inch. Compare that to Tyrannosaurus rex, which had a bite force of 12,000 pounds per square inch, and it's clear you've got a mighty bite on your hands. Still not convinced?
