Answer:
Some differences between the sympathetic and parasympathetic nervous systems:
Explanation:
- Neurotransmitters: norepinephrine in sympathetic (adrenergic fibers) and acetylcholine in parasympathetic (cholinergic fibers)
-The sympathetic nerves have their origin in the spinal cord (between segments T-1 and L-2) and from there to the paravertebral sympathetic chain, then in tissues and peripheral organs.
- The parasympathetic nerves have their origin in the brain stem, mainly in the cranial nerve nuclei III (oculomotor), VII (facial), IX (glossopharyngeal) and X (vagus) and in the sacral medulla.
In order for a scientific theory to be valid, it must be testable. that's true but current physicists are using the non-testable nature of sub atomic particles and matter/energy to put forward crackpot theories based on nothing but ideas and guesswork, global warming is another example, unreliable data being interpreted to match the theory that doesn't stand up to rigorous examination but anyone doing that is immediately demonized and ridiculed
