Key concepts
3 concepts
- 1
The brain's delicate nerve cells, called neurons, communicate through electrical and chemical signals via axons and dendrites.
- 2
During a coup contra coup injury, the brain bounces inside the skull, potentially causing contusions or, in low-speed cases, axonal shearing.
- 3
Mild traumatic brain injuries may not show up on CT or MRI scans, so doctors rely on patient history and clinical exams for diagnosis.
