The innermost layer that the bullet has penetrated is the pia mater. The meninges are the three protective layers that cover the brain and spinal cord. They consist of the dura mater (outer layer), arachnoid mater (middle layer), and pia mater (innermost layer). In this scenario, the bullet has stopped just outside the dura mater, which means it has not reached the pia mater.
To understand the layers, you can think of them as protective layers around an onion. The dura mater is the tough and outermost layer, the arachnoid mater is the fragile and middle layer, and the pia mater is the delicate and innermost layer closely attached to the brain.
It's important to note that sustaining a gunshot wound to the head is a severe and life-threatening injury. Immediate medical attention is necessary to assess and provide appropriate treatment.
