What causes a stellate wound on a gun?

What is a gunshot wound?

When the expansion exceeds skin elasticity and resistance, it will tear, resulting in an entrance gunshot wound with a stellate or irregular appearance. Comment Here Reference: Gunshot wounds

What is the most critical part of forensic pathology?
Determining the range of fire is one of the most critical parts of the forensic pathologist activity; secondary effects of the discharge surrounding the entrance wound (muzzle imprint, soot deposition, stippling or blackening of the skin edges) can help estimate the firing range
What is the difference between internal and external ballistics?
Science that pertains to firearms and bullets; can further be classified as: Internal ballistics: what happens within the firearm from the deflagration to the exit of the bullet from the barrel. External ballistics: the behavior of the bullet while traveling from the firearm to the final target.
What is a long barrel shotgun?
Long guns (shotguns and rifles) Rifled: the barrel contains spiral lands and grooves into the inside of the barrel that grips the bullet as it exits the firearm, providing spin and stabilization along its path. Smoothbore: the barrel is not rifled; typically found in shotguns.
What is exit wound?
Exit wounds: point where the bullet leaves the body. Generally, an exit gunshot wound is more irregular in shape than entry wound. Skin is perforated from the inside out, causing eversion of skin tags and protrusion of tissue from the defect.
Entrance wounds
If the projectile strikes at an angle the injury will be elliptical and the long axis of the ellipse will lie approximately in the plane the bullet traveled.
Exit wounds
Exit defect created whilst surface supported/adjacent to firm surface.
What is a stellate wound?
In contact gunshot wounds with bony tissue underlying the injury, the injuries are typically called a stellate wound, where the gases exit the barrel before the projectile. As a result, the gas collides with the bone tissue, resulting in the reflection of the gases.
What is a gunshot wound?
Gunshot wounds are complex, violent, traumatic injuries commonly encountered in forensic practice. These injuries are caused by penetration of the body with projectiles ejected from a barrel due to the ignition of gunpowder. The study of these injuries is also called wound ballistics. [1] In addition to the injury and the projectile, forensic pathologists must have a working knowledge of the flame, gases, smoke, unburnt powder, metal scrapings, and grease from the barrel that accompanies the projectile and could become embedded in the surrounding skin or the injury tract.
What are the characteristics of a gunshot wound?
The distance and direction of shooting also affect the characteristics of the wound, including the shape, invagination of tissue, the effects of accompanying components including flame, smoke, gas, unburnt particles, metal scraps, and grease. Gunshot wounds can produce two types of wounds, depending on the direction of travel of the projectile. These are entry wounds and exit wounds – entry wounds are generally smaller and more regular than exit wounds. Entry wounds show invagination of tissue into the wound, while exit wounds show outward beveling of tissue. The skin surrounding the entry wound will show the above characteristics, depending on the distance as described later; this includes the presence of flame burns and singeing, soiling and redding from gas, as well as tattooing from unburnt particle and metal scraps. Similarly, the presence of an abrasion rim and grease collar around the wound also indicate that it is an entry wound. ( See Figure 1) However, an abrasion rim may also be present on the exit wound, where the skin is shored against a hard surface.
What is forensic pathology?
The forensic pathologist is often required to identify gunshot wounds, the direction and the distance of fire, the manner of injury - suicidal, homicidal, or accidental, and determine the nature and type of firearm. This activity will provide an overview of gunshot wound evaluation and assessment, leading to improved patient care and outcomes.
Why do people die from gunshots?
Gunshot injuries may result in death due to hemorrhage, organ damage, and wound infection. This information can be extremely important in determining the manner of injury, especially in fatal wounds, to assist medico-legal and criminal investigation on whether the injury was suicidal or homicidal. [2]
How many people died from firearms in 2016?
Globally, in 2016, 251,000 deaths resulted from firearms injuries caused by events not related to war. [4] Gunshot injuries account for the most homicides in the United States of America, accounting for an estimated 46 deaths every day. [3] Other studies have estimated over 90 deaths every day caused by firearm-related injuries. [5] In 2016, the second leading cause of death in children and adolescents was firearm-related injuries accounting for 15.4% of all deaths; Almost two-thirds of these deaths (59%) resulted from homicide, with just over a third (35%) as a result of suicide. Homicide was more common among urban youth than suicide, which was more common in rural youth. The difference in the rates was approximately twice in both cases. [6] Between 1999 and 2013, firearm-related injuries caused the death of 462,043 Americans. [7] In addition to mortality, firearm injuries also cause a massive burden on the health infrastructure, with 282,542 emergency discharges recorded in the USA between 2009 and 2012. [5]

What happens when you shoot a person?
In general, when a person is shot, the injury sustained will result in a temporary wound cavity that is produced due to cavitation, which occurs when a body moves so quickly in a liquid that the liquid detaches from the body surface. This cavity will only exist for a short period of time after the penetration of the projectile. The size and seriousness of the wound cavity will depend on the amount of energy transmitted by the gun, which is dependent on the length of the barrel; the longer the barrel, the greater velocity.

Exit Wounds. Exit wounds, whether they are the result of contact, intermediate, or distant firing, all have the same general characteristics. They are typically larger and more irregular than entrance wounds and, with rare exception, do not possess an abrasion ring.
What is the reddish area of the entrance wound?
Most entrance wounds, no matter the range, are surrounded by a reddish, reddish-brown zone of abraded skin — the abrasion ring (Figure 4.16). This is a rim of flattened, abraded epidermis, surrounding the entrance hole. Fresh entrance wounds have an abrasion ring with a moist, fleshy appearance. As the abrasion ring dries out, however, it assumes ...
