Chapter 27 - Trauma Overview

Question 1

cavitation

Answer 1

a cavity formed by a pressure wave resulting from the kinetic energy of a bullet traveling through the body tissue; also called pathway expansion.

Question 2

dissipation of energy

Answer 2

the way energy is transferred to the human body by the forces acting upon it.

Question 3

drag

Answer 3

the factors that slow a projectile.

Question 4

fragmentation

Answer 4

the breaking up of a bullet into small pieces on impact.

Question 5

kinetic energy

Answer 5

the energy contained by an object in motion. Kinetic energy equals mass (weight in pounds), times the velocity (feet per second) squared, divided by two.

Question 6

kinetics

Answer 6

the branch of mechanics dealing with the motions of material bodies.

Question 7

kinetics of trauma

Answer 7

the science of analyzing mechanism of injury.

Question 8

mechanism of injury (MOI)

Answer 8

the factors and forces that cause traumatic injury.

Question 9

profile

Answer 9

the size and shape of a bullets point of impact; the greater the point of impact the greater the injury.

Question 10

trajectory

Answer 10

the path of a projectile during its travel; a trajectory may be flat or curved.
