Nervous System Flashcards
OTITIS MEDIA
Tenderness upon palpation behind the ear and the eardrum was hyperemic and bulging with purulent effusion during otoscopy
de Mussel’s sign
Rhythmic bobbing of the head that is synchronous with the beating of the heart as a result of aortic insufficiency
DISEQUILIBRIUM
Unsteadiness or imbalance when walking, usually seen in older patients
STEEPLE HEAD
Abnormality of the head that resulted from a premature synostosis of the coronal and sagittal sutures
BITEMPORAL HEMIANOPSIA
Visual field defect that results from a lesion at the optic chiasm
EXOPTHALMUS
Protrusion of the eyeball; common feature of Grave’s disease
CHANCRE
Painless, non-suppurative, ulcerated papule with an indurated edge
TORUS PALATINUS
Midline bony growth in the hard palate that is fairly common in adults
ATROPHIC GLOSSITIS
Smooth and often sore tongue that has lost its papillae that suggests deficiency in Riboflavin, Niacin, Folic Acid, V B12, Pyridoxine or iron or treatment with chemotherapy
HIPPOCRATIC FACIE
Drawn, pinched and pale appearance of the face, indicative of approaching death
RISOS SARDONICUS
Tonic spasm of facial muscles with the angles of the mouth drawn out and eyebrows raised, frequently seen in patients with Tetanus
CORNEAL ARCUS
Grayish white arc or circle not quite at the edge of the cornea and it usually accompanies normal aging
Cranial V and VII
Nerves involved in corneal reflex
TREMOR
Rhythmic oscillatory movement that is the most common movement disorder
SYMPATHETIC NERVOUS SYSTEM
Mobilizes organs and their functions during times of stress and arousal
SYMPTOMATIC ISCHEMIC STROKE
Focal or global cerebral, spinal or retinal dysfunction cause by CNS infarction
SILENT STROKE
Documented CNS infarction that was asymptomatic
Transient ischemic attack
Transient episode of neurological dysfunction caused by focal brain, spinal cord, or retinal ischemia, without acute infarction
Corticospinal tract
Mediates voluntary movement and integrate skilled, complicated, or delicate movements by stimulating selected muscular actions and inhibiting others.
Spinothalamic tract
Pain, temperature, and crude touch
Basal ganglia system
Helps to maintain muscle tone and to control body movements and walking
Middle cerebral artery
Most common cause of ischemic symptoms is occlusion which causes visual cuts and contralateral hemiparesis and sensory deficits
Stereognosis
Tested by manipulating an object and asking to identify
Romberg test
Stand with feet together then open and close both eyes for 30-60 seconds without support
