Loss of memory of events that occurred after a traumatic event to the brain; an inability to recall new information.
Antegrade amnesia
Long, slender projection of a nerve cell (neuron) that conducts electrical impulses away from the neuron’s cell body.
Axon
A bruise involving the brain.
Cerebral contusion
Temporary unconsciousness (unresponsiveness) or contusion caused by a blow to the head.
Concussion
Dual-impacting of the brain into the skull; coup injury occurs at the point of impact; contrecoup occurs at the opposite side of impact, as the brain rebounds.
Coup-contrecoup brain injury

Lucid interval

Retrograde amnesia
Keeping a patient’s spine anatomically aligned during removal from an accident, therefore preventing any neurologic damage.
Stabilized extrication
An accumulation of venous blood between the outer covering of the brain (dura mater) and the surface of the brain
Subdural hematoma
Physical trauma to the brain
Traumatic brain injury (TBI)
