| The brain and its membranes
|
|
Dissection. To examine the brain with its membranes, the skull cap should first be removed. This may be effected by sawing through the external table, commencing, in front, about an inch above the margin of the orbit, and extending, behind, to a level with the occipital protuberance. The internal table must then be broken through with the chisel and hammer to prevent injury to the investing membranes or brain, and after having been loosened, it should be forcibly detached, when the dura mater will be exposed. The adhesion between the bone and the dura mater is very intimate, and much more so in the young subject than in the adult.
The membranes of the brain are the dura mater, arachnoid membrane, and pia mater.
