Chapter 8 CNS Flashcards
(13 cards)
cute inflammation of the pia mater and arachnoid, two of the membranes covering the brain and spinal cord.
meningitis
suppurative process in the space between the inner surface of the dura and the outer surface of the arachnoid.
subdural empyema
most common primary malignant brain tumors, consist of glial cells
glioma
benign tumors that arise from arachnoid lining cells and are attached to the dura
meningioma
slowly growing benign tumors that may occur as solitary lesions or as part of the syndrome of neurofibromatosis
acoustic neuroma
tumors that arise from remnants of the notochord (the embryonic neural tube).
chordoma
caused by acute arterial bleeding and most commonly form over the parietotemporal convexity.
epidiural hematoma
most commonly from ruptured veins between the dura and meninges
subdural hematoma
injury to brain tissue caused by movement of the brain within the calvaria after blunt trauma to the skull
cerebral contusion
most common demyelinating disorder; it manifests as recurrent attacks of focal neurologic deficits that primarily involve the spinal cord, optic nerves, and central white matter of the brain
multiple sclerosis
inherited (autosomal dominant) condition that predominantly involves men and appears in the early to middle adult years as dementia and typical choreiform movements (involuntary movements that are rapid, jerky, and continuous).
huntingtons disease
is a progressive degenerative disease characterized by stooped posture, stiffness and slowness of movement, fixed facial expression, and involuntary rhythmic tremor of the limbs that disappears with voluntary movement.
parkinsons disease
dilation of the ventricular system that is usually associated with increased intracranial pressure.
hydrocephalus
