Lesions along the sympathetic pathway along the external carotid pathway will cause what?
vasodilation and anhydrosis

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

ciliospinal reflex (assesses sym fnxn in in head and face)

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?

What muscle is responsible for lens thickening which allows for the patient to see and focus?
What is its innervation?
ciliary muscles;

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?

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

False; must be proximal

What is the cardinal finding in CN XII disease?
paralysis of the tongue
What is the cardinal finding in CN XII disease?
paralysis of the tongue
What is the term for loss of vibratory perception?
pallanesthesia
T/F: If a patient falls during the Romber Test with his eyes open, it signifies a dorsal column pathology.
False; eyes closed
