Question 1

what are the receptors for the sympathetic and parasympathetic NS?

Answer 1

-sympa: epi,norepinephrine, dopamine which attach to ADRENERGIC receptors (alpha,beta)
-parasympathetic: acetylcholine attach to cholinergic (muscaritic , nicotinic)

Question 2

what do anticholinergic meds do?

Answer 2

they stop the para system so it stops digestion and activates sympathetic

tension headache

Answer 12

-most common
-has to happen at least 15 days per month for 3 months

Question 13

Myasthenia Gravis

Answer 13

-type II hypersensitivity AI that makes antibodies to acetylcholine receptors causing weakness in muscle
- symp: progressive weakness, ptosis, diplopia (seeing double),dysphagia, DIAPHRAGM STOPS WORKING

Question 14

how do you test for myasthenia graves?

Answer 14

-tensilon test which tests positive if patient improves
-its anticholinergic which allows acetylcholine to accumulate allowing for a better contractioni

Question 15

in cholinergic cris, there will be too much ___, causing ___ GI/GU, with __ HR,RR,BP. this will happen if a patient with the tensilon test ___.

Answer 15

-acetylcholine, increased , low, worsens

Question 16

Guillain Barre syndrome

Answer 16

-demyelinating syndrome in PERIPHERAL NERVES
-starts from bottom to top, due to infection and will have resp infection or GI after
-symp: paresthesia, resp arrest
-treatment: ventilator, IVIG, plasmaphereis

Question 17

Parkinsons

Answer 17

-chronic/progresive in basal ganglia,substantia nigra which produce dopamine
-this causes low levels of dopamine compared to acetylcholine
-symp: TRAD (tremors @ rest, rigidity, bradykinesia, postural disturbance)
-treatment: replace dop, anticholinergic drugs

Question 18

In a man with Parkinson’s, what will you see?

Answer 18

lewy bodies (clumps of protein)

-symp: weakness of muscles, normal intellectional function
-treat:2-5 yrs life expectactny , antiglutamtte

Question 20

Multiple sclerosis

Answer 20

-demyelinating in CNS; T helps mark myelin as foreign
-symp:paresthesia, hard to walk, loss of eye movement, impaired gait
-lesions present, high IgG
treatment: avoid extreme temp, immunosuppressants

spinal shock

Answer 21

-COMPLETE loss of reflex, motor, sensor and autonomic below lesion
-regain everything, may take to 3 months

Question 22

Autonomy dysreflexia

Answer 22

-happens if injury is at T6 or above
-can’t empty bladder/rectum, high sympathetic NS= high BP, low HR
