Flexor carpi ulnaris muscle Flexor carpi ulnaris muscle The flexor carpi ulnaris muscle (or FCU) is a muscle of the human forearm that acts to flex and adduct (medial deviation) the hand. Flexor carpi ulnaris muscle arises by two heads, humeral and ulnar, connected by a tendinous arch beneath which the ulnar nerve and artery pass. Its insertion is into the pisiform bone, into the hamate bone via the pisohamate ligament and into the fifth metacarpal bone via the pisometacarpal ligament. The muscle acts to flex and adduct the wrist joint. The flexor carpi ulnaris muscle is innervated by the ulnar nerve which has
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
