Forensic Pathology Quiz 6

The severity, extent, and appearance of injuries due to blunt force trauma depend on

Skin injuries in which there is removal of the superficial epithelial layer due to friction against a rough surface or by compression are called

When a blunt object scrapes off the skin's superficial layers leaving a denuded surface, a __________________ is produced.

Abrasions heal without scarring.

Contusions are more readily incurred in areas with thick skin that protects lean areas of the body.

Spectacle hematomas (a/k/a Racoon Eyes) are a type of contusion surrounding the soft tissues around the eyes.

The woman whose picture appears in the photo labeled "face-2.jpg" sustained blunt force trauma to her eyes (e.g., punches to the face that hit the eyes).

As depicted in the photo entitled "face-3.jpg," the type of blunt force trauma that is often observed over the eyebrows, the cheekbones, and/or the nose that results when an unconscious individual collapses is called a(n):

Which of the following is the first stage of abrasion healing, indicating that the person likely survived at least four to twelve hours following a blunt force injury?

The initial appearance of an abrasion is dark blue, purple, or crimson. As hemoglobin breaks down, it changes to violet, green, dark to pale yellow, and eventually disappears.

Because the healing rate for contusions is relatively constant, a reasonably accurate estimate of how old a bruise is can be made from the color of the healing contusion.

The size and severity of a contusion is indicative of the amount of force applied only.

Contusions usually indicate injury before death, although it is possible (yet very rare) for a contusions to be made postmortem if a severe enough blow is delivered within a few hours of death.

Lacerations of the skin tend to be irregular with abraded, contused margins.

Although there are exceptions, as a general rule, long objects tend to make irregular or Y-shaped lacerations, while flat objects tend to make linear lacerations.

Bridging of a wound is indicative of a sharp force injury.

An avulsion is a type of laceration.

A fracture, defined as a disruption in the continuity of a bone due to an applied force, typically appears as a linear lucency on a radiological exam.

Fractures can be caused by either direct or indirect force to the bone.

A compound fracture is one in which there are three or more breaks in a bone.

Transverse fractures of the sternum may be caused by the administration of CPR.

A massive crushing force to the chest may lacerate the pericardium.

Lungs can usually withstand compression without injury, but a sudden, forcible blow may cause a lung contusion.

The absence of external injuries to the abdomen generally indicated that there are no serious internal injuries to the tissue or organs contained in the abdomen.
