ATCN Chapter 6. Head TraumaThe primary goal of treatment for patients with suspected TBI's is to prevent
___________________________________________. - ANS-Secondary Brain injury
The most important ways to limit secondary brain damage and thereby improve a
patients outcome are to - 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 ????? - 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. - 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. - ANS-Meningeal arteries
The _____________________________________ is the most common injured artery,
located over the temporal fossa. - ANS-The middle meningeal artery
__________________________________________ space between the dura mater
and the arachnoid mater - 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. - 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. - 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. - ANS-Cerebrum
________________________________ controls executive function, emotions, motor
functions, and on the dominant side, expression of speech. - ANS-Frontal Lobe
___________________________ directs sensory function and spatial orientation, the
temporal lobe regulates certain memory functions, and the occipital lobe is responsible
for vision. - ANS-Parietal Lobes
Brain Stem
__________________________________ contains the reticular activating systems
which is responsible for the state of alertness. - ANS-Midbrain and upper pons
Vital cardio respiratory centers reside in the _____________________________, which
extends downward to connect with the spinal cord, - ANS-Medulla
The _______________________________ is responsible mainly for coordination and
balance, projects posteriorly in the posterior fossa and connects to the spinal cord, brain
stem, and cerebral hemispheres. - ANS-Cerebellum
______________________________________ are a system of CSF filled spaces and
aqueducts within the brain. CSF is constantly produced with the ventricles and
absorbed over the surface of the brain. The presence of blood in the CSF can impair its
reabsorption, resulting in increased intracranial pressure. - ANS-Ventricular System
The meninges partitions separate the brain into regions. The tentorium cerebelli divides
the intracranial cavity into : - ANS-The Supratentorial and infratentorial compartments.
The mid Brian passes through the opening called the ? - ANS-Tentorial hiatus or notch
