Answer;
Stimulation of thoracic or lumbar spinal regions; impulse reaches chain ganglion; acetylcholine release
Explanation;
- The sympathetic nervous system is part of the autonomic nervous system, which also includes the parasympathetic nervous system.
- The sympathetic nervous system functions by activating the fight or flight responses. It operates through a series of interconnected neurons.
- Sympathetic neurons of the spinal cord communicate with the PNS via a series of sympathetic ganglia. Spinal cord sympathetic neurons joins with the peripheral sympathetic neurons through the chemical synapses.
- At synapses, preganglionic sympathetic neurons release acetylcholine, which binds and activates nicotinic acetylcholine receptors on the postganglionic neurons.
