Question

time for your first knowledge check! if kirk does have a concussion, what do you think is happening inside his head? remember, you earn points for right answers, and you need at least 80 points to pass. his brain’s blood vessels have constricted, reducing the flow of blood to the brain. he has suffered a traumatic brain injury and possible movement of the brain within the skull. the head impact is now causing a growth to develop inside his brain. his brain is now more “loose” inside his skull, causing it to move around even if he stays still.

Explanation:

A concussion is a type of traumatic brain injury. It occurs when the head is hit, causing the brain to move rapidly inside the skull. There is no indication that concussion causes blood - vessel constriction, immediate brain growth, or the brain becoming "loose" in the way described.

Answer:

He has suffered a traumatic brain injury and possible movement of the brain within the skull.
