Sympathetic nervous system elevates blood pressure. Long term, decrease in capillary blood
pressure recalls fluids from interstitial spaces. Aldosterone and ADH promote
fluid retention. Increased thirst promotes water absorption across the
digestive tract. Short term, Carotid and aortic reflexes move up cardiac output
and peripheral vasoconstriction.
Blockade of the acetylcholine receptors at the neuromuscular junction will lead to decreased or inhibited depolarization of the involved muscle leading to flaccid paralysis. This is similar in presentation to myasthenia gravis when there is autoimmune destruction of acetylcholine receptors at the neuromuscular junction.
