30 Questions
What are the two types of cavity caused by a projectile?
Permanent and temporary
What are the two destructive mechanisms of GSW?
Laceration and crushing, shock waves
At what velocity can generated shock waves reach up to 200 atmospheres of pressure?
High velocity
What do hollow point and soft nose bullets do on impact?
Flatten out
What is the main factor that contributes to the size of the permanent tract?
Bullet size
What is the difference between a permanent cavity and a temporary cavity?
A permanent cavity is caused by the path of the bullet itself, whereas a temporary cavity is formed by continued forward acceleration of the medium in the wake of the bullet
What is the effect of shock waves at low velocity?
They do not cause profound destruction
What is the difference between laceration and cavitation?
Laceration is tissue damage through the path of the bullet, whereas cavitation is the formation of a permanent and temporary cavity
What is the effect of bullet deformity on surface area involved?
It increases the surface area involved
What is the effect of bullet size on the size of the temporary cavity?
It increases the size of the temporary cavity

What is the term used to describe the tissue damage caused by the path or 'track' of a projectile through the body?
Cavitation
What is the difference between a 'permanent' cavity and a 'temporary' cavity?
The permanent cavity is caused by the bullet's path, while the temporary cavity is caused by shock waves
At low velocity, what is the effect of shock waves on the medium through which a bullet travels?
Shock waves do not cause profound destruction
What is the relationship between bullet size and the size of the permanent tract?
The larger the bullet, the more resistance and the larger the permanent tract
What happens to hollow point and soft nose bullets upon impact?
They flatten out on impact, resulting in larger surface area involved
What is the term used to describe the continued forward acceleration of the medium in the wake of a bullet, causing the wound cavity to be stretched outward?
Cavitation
At high velocity, what is the maximum pressure that shock waves can reach?
200 atmospheres
What is the term used to describe the factors that contribute to tissue damage from a gunshot wound?
Wound Ballistics
What is the effect of shock waves on the medium through which a bullet travels?
Shock waves compress the medium and travel ahead of the bullet, causing profound destruction
What is the relationship between bullet deformity and the surface area involved in tissue damage?
Bullet deformity increases the surface area involved in tissue damage
