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.
Hydrocodone and acetaminophen combination is used to relieve moderate to moderately severe pain. Acetaminophen is used to relieve pain and reduce fever in patients. It does not become habit-forming when taken for a long time. But acetaminophen may cause other unwanted effects when taken in large doses, including liver damage. Hydrocodone belongs to the group of medicines called narcotic analgesics (pain medicines). It acts on the central nervous system (CNS) to relieve pain, and stops or prevents cough. When hydrocodone is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain.
