Even More Test 1 Highlights Flashcards
What is the other term for cormiosis, a common sign of Horner’s Syndrome?
pupilloconstriction
What are the 4 common S/S of Horner’s Syndrome?
Ptosis, Pupilloconstriction, Facial Anhydrosis, Ipsilateral Facial vasodilation
Lesions along the sympathetic pathway distal to the bifurcation of the common carotid (along the internal carotid pathway) will not cause all 4 classic S/S of Horner’s. What will lesions here cause?
pupilloconstrictin and ptosis only
Lesions along the sympathetic pathway along the external carotid pathway will cause what?
vasodilation and anhydrosis
Theoretically, disruption of sympathetic impulses to the small muscle of Muller will cause what?
Enophthalmos (inward sinking eyes)
Checking for eyelid ptosis, pupil asymmetry, and ocular deviations describes the examination of what cranial nerves?
CN III, IV, and VI
T/F: Eyelid ptosis may indicate a lesion to the hypothalamus, brain stem, spinal cord, or peripheral sympathetic nerves.
True
What reflex involves pinching the skin on the patient’s neck and observing for brisk bilateral pupillodilation?
ciliospinal reflex (assesses sym fnxn in in head and face)
What is the term for failure to perceive light stimulus?
medical blindness
What is confrontation used to assess?
peripheral vision
T/F: Convergence is accomplished by the medial rectus muscles and dependednt on CN II function.
False; CN III
T/F: Pupilloconstriction is accomplished by parasympathetic fibers traveling within CN II.
False; CN III
What muscle is responsible for lens thickening which allows for the patient to see and focus?
What is its innervation?
ciliary muscles;
CN III
What muscle is responsible for lens thickening which allows for the patient to see and focus?
What is its innervation?
ciliary muscles;
CN III
When performing the Swinging Flashlight Test, what is it called if the pupil dilates when it should constrict?
Marcus-Gunn phenomenon
What is the term for collections of degenerative deposits that often appear in the fundus of elderly people and are considered clinically insignificant?
Drusen Bodies
T/F: CN V supplies the cutaneous innervation over the angle of the jaw.
False; this is the great auricular nerve of the cervicoplexus (C2, C3 dermatome)
T/F: Forehead mov
ement is usually spared in unilateral lesions involving corticobulbar pathways.
True, hence stroke victims may still exhibit bilateral forehead movement
What is prosopoplegia?
peripheral facial paralysis
What is ageusia?
complete taste loss
T/F: Peripheral lesions to CN VII must be distal to te stylomastoid foramen to affect taste.
False; must be proximal
T/F: Peripheral lesions to CN VII must be distal to te stylomastoid foramen to affect taste.
False; must be proximal
Nerve of perceptive hearing loss is usually attributed to disease of what organ?
Organ of corti (inside the cochlea) or the auditory nerve
What is the cardinal finding in CN XII disease?
paralysis of the tongue
