Metacarpal bones Metacarpal bones In human anatomy, the metacarpal bones or metacarpus, form the intermediate part of the skeletal hand located between the phalanges of the fingers and the carpal bones of the wrist which forms the connection to the forearm. The metacarpal bones are equivalent to the metatarsal bones in the foot. The metacarpals form a transverse arch to which the rigid row of distal carpal bones are fixed. The peripheral metacarpals (those of the thumb and little finger) form the sides of the cup of the palmar gutter and as they are brought together they deepen this concavity. The index
Human Shadow Etched in Stone depicted in the stone. According to museum staff, many visitors to the museum believe that the shadow is the outline of a human vaporized immediately after the bombing. However, the possibility of human vaporization is not supported from a medical perspective. The ground surface temperature is thought to have ranged from 3,000 to 4,000 degrees Celsius just after the bombing. Exposing a body to this level of radiant heat would leave bones and carbonized organs behind. While radiation could severely inflame and ulcerate the skin, complete vaporization of the body is impossible. Human Shadow Etched in Stone was originally part
