Q&A 100% Verified Solution A+
The primary goal of treatment for patients with suspected TBI's is to prevent
___________________________________________. - Correct Ans-Secondary Brain injury
The most important ways to limit secondary brain damage and thereby improve a patients outcome are
to - Correct Ans-Ensure adequate oxygenation and maintain blood pressure at the level that is sufficient
to perfuse the brain.
Skull
Anterior Fossa - Houses ??????
Middle Fossa - Houses ?????
Posterior Fossa - houses ????? - Correct Ans-Anterior Fossa - Houses the frontal lobes
Middle Fossa - Houses the temporal lobes
Posterior Fossa - contains the lower brain stem and cerebellum
Meninges
___________________________________ is a tough fibrous membrane that adheres firmly to the
internal surface of the skull, at specific sites, the ________________ splits into two "leaves" that enclose
the large venous sinuses, which provide the major venous drainage from the brain. - Correct Ans-Dura
Mater / Dura.
______________________________________ lie between the dura and the internal surface of the skull
in the epidural space. Overlying skull fractures can lacerate these arteries and cause an epidural
hematoma. - Correct Ans-Meningeal arteries
The _____________________________________ is the most common injured artery, located over the
temporal fossa. - Correct Ans-The middle meningeal artery
__________________________________________ space between the dura mater and the arachnoid
mater - Correct Ans-Subdural space
Beneath the dura is a second meningeal layer: the thin, transparent arachnoid mater. Because the dura
is not attached to the underlying arachnoid membranes a potential space between these layers exists
(the subdural space) into which hemorrhage can occur. - Correct Ans-In a Brian injury, bridging veins
that travel from the surface of the brain to the venous sinuses within the dura may tear, leading to the
formation of a subdural hematoma.
______________________________________ is firmly attached to the surface of the brain. Cerebral
spinal fluid fills the space between the watertight arachnoid mater and the pia mater. (Subarachnoid
space) Hemorrhage into this fluid filled space frequently accompanies brain contusion and injuries to
major blood vessels at the base of the brain. - Correct Ans-Pia Mater
_____________________________________________ right and left sides are separated by the falx. The
left hemisphere contains the language center in virtually all right handed people and in more than 85%
of left handed people. - Correct Ans-Cerebrum
________________________________ controls executive function, emotions, motor functions, and on
the dominant side, expression of speech. - Correct Ans-Frontal Lobe
___________________________ directs sensory function and spatial orientation, the temporal lobe
regulates certain memory functions, and the occipital lobe is responsible for vision. - Correct AnsParietal Lobes
Brain Stem
__________________________________ contains the reticular activating systems which is responsible
for the state of alertness. - Correct Ans
