What lobe of the brain is impacted by the nail? What function of the brain may Mauro have damaged in this accident?
Football helmets cover the entire braincase and provide a lot of protection to the player's head. However, concussions are still very common in football. The brain is made of soft nervous tissue and is surrounded by a layer of spinal fluid. When a football player collides with another player/ground/etc the impact can jolt the brain and cause it to move around inside your head. Traumatic brain injuries, like concussions, can cause bruising, damage to the blood vessels, and injury to the nerves.
Why do you think concussions are still a health concern in football, even though the football helmet is very protective?
