Dural spaces Flashcards
Dura mater space name
Epidural space
What type of space is the epidural space of the dura mater?
Potential space
Epidural space location
Located between the dura mater and the bones of the cranial vault (cranial) or tissues that line the vertebral canal (spinal)
The epidural space transmits
cerebral veins to the venous lacunae of the superior sagittal sinus
The epidural space transmits cerebral veins to the venous lacunae of the superior sagittal sinus, laceration of these ‘bridging veins’ results in:
extra/epidural haemorrhage (haematoma
Spinal epidural space is a site of
applying the local epidural anaesthesia
Two spaces of the arachnoid mater
Subdural space
Subarachnoid space
What type of space is the subdural space?
Potential
The subdural space of the arachnoid mater is located
between the arachnoid mater and dura mater
Subdural space can develop as a result of
haemorrhage inducing brain trauma (e.g. subdural haematoma)
What type of space is the subarachnoid space of the arachnoid mater?
Real space
Subarachnoid mater is located
between arachnoid mater and pia mater
The subarachnoid space contains
Arachnoid trabeculae
The subarachnoid space is traversed by many
arteries and veins
