Detailed explanation-1: -EXAMPLES. Physiological changes induced by the sympathetic nervous system include accelerating the heart rate, widening bronchial passages, decreasing motility of the large intestine, dilating the pupils, and causing perspiration.
Detailed explanation-2: -Public speaking can be very stressful. How can anticipating giving a public speech stimulate the sympathetic nervous system? During stress, multiple preganglionic neurons can synapse on one postganglionic neuron, and the adrenal gland releases adrenaline.
Detailed explanation-3: -The SNS governs the “fight or flight” response while the PNS controls the “rest and digest” response. Fibers from the SNS innervate tissues in almost every organ system and provide physiological regulation over diverse body processes including pupil diameter, gut motility (movement), and urinary output.
Detailed explanation-4: -Heart rhythm issues (including arrhythmias). Constipation. Dizziness or passing out when standing up. Eyelid droop (ptosis). Fast heart rate (tachycardia), even when resting. Sexual dysfunction, including priapism. More items •06-Jun-2022
