Question

What three things are seen at the cellular level in mild TBI?

Answer 1

At the cellular level in mild TBI, three things can be seen: neuronal damage, gliosis, and inflammation.

Step-by-step explanation:

At the cellular level in mild Traumatic Brain Injury (TBI), three things can be seen:

1. Neuronal damage: TBI can cause damage to the structure and integrity of neurons in the brain, leading to necrosis (cell death) of neurons.
2. Gliosis: Following TBI, glial cells in the brain respond by proliferating, which is known as gliosis. This is a protective mechanism to help repair and support damaged neurons.
3. Inflammation: TBI triggers an inflammatory response in the brain, characterized by the influx of inflammatory cells and release of inflammatory molecules. This inflammatory response can contribute to secondary brain damage.
