List some of the organs effected by the parasympathetic nervous system?
550824
The parasympathetic nervous system is antagonistic to the sympathetic nervous system. It's not that one tries to be active all the time, they work together and one is more active than the other in certain types of situations. \n\nThe parasympathetic system does the following:\n\nHeart - slows it down\npupils - constricts them\nlungs - constricts airways\nstomach - stimulates digestion\nintestines - dilates blood vesssels so that more blood can go to the intestines\nbladder - stimulates it\ngenitals - stimulates erection

Parasympathetics "point" (erection)\nSympathetics "shoot" (ejaculate)

It's not really a question of what's effected - its more of a progression.  The ones to go first really depend on what is causing the loss in homeostasis.  Then these first organs may effect other organs.  For example, if potassium is off - it will effect the heart.  However, if kidneys fail for some reason and affect the balance of ions in the body, then they will eventually affect other organs.  So it is a tough question to answer, but any organs may be affected and it will depend on what the cause is.  \nMostly the big organs you worry about are heart, kidney, liver, CNS (brain), lungs.

Neural stimulus of the endocrine organ (eg. sympathetic nerve stimulus of adrenal gland to release adrenaline/epinephrine)\n\nIntrinsic stimulus by organ itself (eg. parathyroid glands react to low serum Ca levels & release parathyroid hormone)\n\nHormonal stimulus of the organ (eg. pituitary gland releases thyroid stimulating hormone to act on the thyroid gland to release growth hormone)

the autonomic nervous system is under involuntary control and the somatic nervous system is under voluntary control\n\nthere would be a lot more axons in the somatic nervous system because of muscle movement

Nervous system is the control center which consists of Brain, Spinal Cord and an enormous network of nerves that spread throughout your body. These nerves are responsible for the information flow between nervous system and other systems [ digestive, respiratory, circulatory etc etc ] in the entire body. Nervous system controls and coordinates the functioning of all other systems that exists in a body.

* Cardiovascular system: blood circulations with heart and blood vessels\n    * Digestive system: processing food with mouth, stomach and intestines\n    * Endocrine system: communicating within the body using hormones\n    * Immune system: defending against disease-causing agents\n    * Integumentary system: skin, hair and nails\n    * Lymphatic system: structures involved in the transfer of lymph between tissues and the bloodstream\n    * Muscular system: moving the body\n    * Nervous system: collecting, transferring and processing information with brain and nerves\n    * Reproductive system: the sex organs\n    * Respiratory system: the organs used for breathing, the lungs\n    * Skeletal system: structural support and protection through bones\n    * Urinary system: the kidneys and associated structures involved in the production and excretion of urine

Autonomic nervous system
999857
In the whole autonomic nervous system there are 3 main hormones/neurotransmitters\n\n1)Adrenaline\n2)Noradrenaline\n3)Acetylcholine\n\nAdrenaline/Noradrenaline both stimulate the same receptors (alpha and beta adrenergic) but to different extents. (Think ADRENaline = ADRENergic. Both adrenaline and noradrenaline have ADREN in their name) AcetylCHOLINE stimulates CHOLINErgic receptors\n\nAll these transmitters are found in both the sympathetic and parasympathetic branches of the autonomic system

1.heart\nMain component of the circulatory system. It pumps blood to spread oxygen and nutrients to all over the body and to get some of the waste.\n2.Lungs\nTo take oxygen and put it in the blood.\n3Liver\nCleans toxins out of your body.\n4Kidneys\nThis one is my weakest answer - I know it helps filter your urine in some way.\n5.Stomach and intestines\nAbsorb nutrients from food.\n6.Mucles\nTo move.\n7.brain\nTo control the body.\n8.Bladder\nSo you don't piss yourself.

http://www.thedoctorslounge.net/studlounge/mnemonics/anatomy.htm\nWarning: many of the mneumonics are dirty, dirty, dirty!\nWith physiology it's helpful to compare/contrast systems such as parasympathetic versus sympathetic or adrenergic or muscarinic receptors, etc...

The central nervous system is made up of the brain and the spinal cord. \nThe peripheral nervous systems is structurally made up of cranial nerves, spinal nerves, ganglia and sensory receptors( eye, ears etc.) Functionally, the PNS is divided into somatic and autonomic. The somatic system is under our control and involves skeletal muscle contraction. The autonomic system is further subdivided into parasympathetic and sympathetic. The  parasympathetic is the system responsible for everyday function such as digestion etc.; it is known as the rest or repose system. The sympathetic acts only when in a stress situation and is related to survival; it is known as the fight or flight system.
