Q

Name the function of the Dural Venous Sinuses.

A

Internal venous blood Chanels allowing venous blood to drain into the big veins of the neck.

47
Q

What is the risk associated with a blunt traumatic force to the mid face (maxillary region)

A

The maxillary portion of the mid cranium could potentially be pushed back up into the bad of the base of the skull piercing the Neuro cranium leading to brain damage.

48
Q

What happens when the Maxillary Region sustains a blow.

A

The inbuilt crumple zone region of the maxilla will dissipate the force to reduce or prevent damage to the nurocranium.
