Ответ:
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.
