Concussion Anatomy
Mechanism of Injury
![](http://upload.wikimedia.org/wikipedia/commons/thumb/6/67/Concussion_Anatomy.png/220px-Concussion_Anatomy.png)
Branch of mechanics that describes motion, so in this context the movement and interaction in collisions.
An object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force.
Forces can be blunt or penetrating. Some of the forces involved in the mechanism of injuryː
- Acceleration
- Deceleration
- Combination of acceleration and deceleration
- Rotational
- Deformation
- Velocity and speed
Injury Mechanism:
- An accelerating/decelerating injury occurs when there is direct contact producing an abrupt change in speed.
- A shearing injury occurs when two oppositely directed and parallel forces are applied to tissue.
- A compression injury is caused when squeezing forces push inward pressure onto the tissues.
