Disorders of the ANS Flashcards
What nerve is referred to as the Edinger Westphal
III
What nerve is referred to as the Superior salivary
VII
What nerve is referred to as the Inferior salivary
IX
What nerve roots attach to salivary glands
VII, IX
What nerve roots contain Ciliary muscles and Pupilary Sphincters
III
What tissues occupy the T1 root value
Salivary Glands
Sweat Glands
Radial Muscles
Superior Palpebrae
What are the ANS effects in the head during sympathetic activation
Mydriasis Elevation of the eyelids Exophthalmosis Vasoconstriction Increased sweating
What are the ANS effects in the head during parasympathetic activation
Miosis
Bulging of lens of the eye for near vision
Damage to the superior cervical ganglion or sympathetic outflow from T1 will result in:
Miosis on the affected side Ptosis (drooping) Enophthalmosis (sinking of the eyeballs) Anhydrosis (failure of sweat glands) Vasodilatation HORNER'S SYNDROME
What is being stretched during blood pressure control
Aortic Arch & Carotid sinus
What nucleus is involved in the decrease in heart rate by inhibition the sympathetic system
Rostral Ventrolateral Nucleus
What nucleus is involved in the decrease in heart rate by promoting the parasympathetic system
Nucleus ambiguus
What is the term for sudden dizziness upon standing due to a rapid fall in B.P
Postural (Orthostatic) Hypotension
What kind of drugs are used to counteract the effect of Postural (Orthostatic) Hypotension
Sympatholytic Drugs (α adrenergic blockers)
True or False, Postural (Orthostatic) Hypotension causes widespread disruption of ANS functioning
True e.g. HR changes that should accompany BP changes are absent
What procedure is used in the treatment of Postural (Orthostatic) Hypotension
Surgical sympathectomy
What disease is Postural (Orthostatic) Hypotension associated with
Diabetic autonomic neuropathy, Familial dysautonomia, Guillain-Barré, syphilis etc.
What symptoms are associated with Familial Dysautonomia (RILEY-DAY SYNDROME)
Absence of tears, Postural hypotension, Labile blood pressure, Excessive salivation and sweating Fluctuations in body temperature Dysphagia and vomiting crises
What age group is Familial Dysautonomia (RILEY-DAY SYNDROME) associated with
Infants/ children
What disease causes an Interruption of the afferent nerves to the bladder
Tabes Dorsalis (syphilitic myelopathy)
What causes an Interruption of both afferent and efferent nerves
Tumors
What plexus is absent in Hirschsprung’s disease / Megacolon
Myenteric Plexus in the distal colon
True or False, children with Hirschsprung’s disease / Megacolon defecate frequently
False, It’s infrequently
