27.
A 28-year-old man sustains a gunshot injury to the thigh. Imaging shows that the bullet has flattened inside the tissues and produced a wound track wider than its original diameter. Which factor best explains the increased tissue destruction?
28.
A 28-year-old man sustains a gunshot injury to the thigh. Imaging shows that the bullet has flattened inside the tissues and produced a wound track wider than its original diameter. Which factor best explains the increased tissue destruction?
29.
A high-velocity projectile enters the abdomen, fragments after striking the pelvis and produces several additional wound tracks. What is the main mechanism responsible for these extra tracks?
30.
A firearm projectile rapidly pushes tissues away from its path, after which the tissues recoil. This process produces the:
31.
A man standing near an explosion is thrown several metres and sustains a subdural haemorrhage after striking a wall. Which blast mechanism caused the fatal injury?
32.
A person dies after contact with an exposed electrical wire. At autopsy, a small pale, dry and depressed lesion is present on the hand. This lesion is most consistent with a:
33.
