The parasympathetic and sympathetic components of the autonomic nervous system (ANS) differ in their structure and in their function, but the two systems have some important features in common.he cell bodies of the presynaptic neurons of both the parasympathetic and sympathetic systems are located within the central nervous system. These presynaptic autonomic neurons synapse only with postsynaptic autonomic neurons.
Hydrocodone itself does not cause possible liver damage, but the actual acetaminophen in the pill is what can cause liver damage in high doses. Typically one must consume more then 8,000 mg in a 24 hour period consistently over a period of time to cause damage.cetaminophen is processed by the liver and it takes about 4 hours for the liver to break it down. Taking more then the recommended dosage can cause the liver hardship. Granted going over a few times won't necessarily cause permanent damage, but consistent use may.
The pain meds are not harmful to the liver as long as they don't contain aspirin and acetaminefen and are taken under a Docs care, along with regular blood tests you'll get any way for the treatment. Most pain meds ,codein, hydrocodone, etc.,metabolize to morphine in the liver , so morphine has the least pressure on the liver aslong as you are in good enough shape to rid the liver of the drug and not let it build up.
