Sympathetic nervous system - Wikipedia, the free encyclopedia (827 words) |
 | This response is also known as sympatho-adrenal response of the body, as the pre-ganglionic sympathetic fibers that end in the adrenal medulla (but also all other sympathetic fibers) secrete acetylcholine, which activates the secretion of adrenaline (epinephrine) and to a lesser extent noradrenaline (norepinephrine) from it. |
| Sympathetic nerves originate inside the vertebral column, toward the middle of the spinal cord in the intermediolateral cell column (or lateral horn), beginning at the first thoracic segment of the spinal cord and are thought to extend to the second or third lumbar segments. |
| The first synapse (in the sympathetic chain) is mediated by nicotinic receptors physiologically activated by acetylcholine, and the target synapse is mediated by adrenergic receptors physiologically activated by either noradrenaline or adrenaline. |
| sympathetic magic (388 words) |
| Sympathetic magic is the basis for most forms of divination. |
| Sympathetic magic is the basis for psychometry, the claim of psychic detectives that touching an item belonging to a victim gives magical contact with the victim. |
| Beyerstein also explains many notions of graphologists as little more than sympathetic magic, e.g., the notion that leaving wide spaces between letters indicates a proneness to isolation and loneliness because the wide spaces indicate someone who does not mix easily and is uncomfortable with closeness. |
