Exploration of the spinal cord and meninges in situ
Epidural space in thoracic region
The epidural space lying deep to the 5th, 6th, 7th and 8th thoracic vertebrae has been exposed. A window has been cut through the dura to expose the subdural space with the arachnoid membrane in its depths. The subdural space appears unduly large due to the collapse of the underlying arachnoid.
