A disruption of the continuity of tissues produced by external mechanical force.

A wound that heals in less than 20 days and leaves no permanent infirmity.

A wound that takes more than 20 days to heal or causes permanent infirmity.

A wound that causes death of the victim.

Damage to the superficial layer of the skin (epidermis), often extending into the dermis, causing slight bleeding.

Extravasation of blood into surrounding tissues from damaged capillaries or venules.

The site of an abrasion reflects the site of impact and the sort of assault.

The age of an abrasion can be compared to the date of the assault, providing clues to the event's timing.

The shape of a bruise can be used to determine the object that caused it. For example, a round bruise might be caused by a punch, while a long, thin bruise might be caused by a whip.

Bruises usually appear at the site of the impact, but they can shift from their original location depending on the force and the tissues involved.

The color of a bruise changes over time as hemoglobin breaks down. Fresh bruises are red, then blue, then green, and finally yellow.

The size of a bruise depends on several factors, including the type of tissue, age, sex, and the force of the impact.

Bruises that develop after death are usually small and occur in areas where the body has been pressed against a surface.

A lacerated wound is a tear in the skin caused by blunt force trauma.

Lacerated wounds often show signs of crushing, indicating the impact of the force.

Lacerated wounds are more likely to become infected because of the damaged tissues and the potential for contamination.

An injury caused by a sharp-edged object, such as a knife or razor, that cuts through the full thickness of the skin.

Incised wounds are characterized by clean, regular edges, more length than depth, and profuse bleeding.

The depth of a stab wound extends far beyond the visible surface length, often penetrating deep into the body.

Stab wounds are often elliptical in shape and may reveal the type of blade used, its width, and even the length of the weapon.

Injuries self-inflicted by a person on their own body, often for attention or deception.

Incised wounds typically heal by primary intention, meaning the edges are brought together and the wound closes without a large scar.

Stab wounds often heal by secondary intention, leaving a larger scar because the edges can't be easily brought together.

The age of a wound can be determined by examining its appearance, from redness and swelling in the first day to fading scars over time.

Injury to the skin of the abdomen, often caused by a broad impact, resulting in minimal visible damage.

Internal organs like the liver, spleen, kidneys, and intestines are vulnerable to damage from compression or tearing against the spine during blunt trauma.

Stab wounds that penetrate the abdomen can cause significant blood loss by damaging major blood vessels like the aorta and vena cava, resulting in blood pooling within the peritoneal cavity.

Inflammation of the peritoneum, often caused by damage to intestines, leading to a severe infection.

This is any injury to the scalp, skull, meninges, and brain caused by mechanical trauma.

Injuries intentionally inflicted by the victim to support a false claim of assault.

Injuries sustained by the victim while defending themselves from an attack.

A life-threatening condition caused by the body's inability to maintain adequate blood flow to vital organs.

Caused by a loss of blood volume, leading to decreased blood pressure and tissue perfusion.

Caused by the failure of the heart to pump blood effectively, resulting in inadequate oxygen delivery.

Caused by a severe infection, leading to widespread inflammation and organ dysfunction.

Caused by a rapid and excessive release of inflammatory mediators, leading to vascular instability and organ damage.

Caused by a life-threatening allergic reaction to a substance, leading to rapid swelling and airway obstruction.
