Q

External forces of TBI

A
  • Acceleration, deceleration, rotational forces relative to bony skull
  • Compression, strain, shearing, displacement of brain tissue
  • Penetrating object –> laceration and contusion of brain tissue
  • Glial cells vs neurons: rapid atmospheric pressure changes in blast-related injuries; neuron cells intact (resilient), glial cells (support for neurons) damaged and die - send out toxins that kill off neurons
