ANSWER C. oNE ACCELERATES AND ONE INHIBITS ACTIONS OF THE ORGAN
The sympathetic nervous system is antagonistic to the parasympathetic nervous system. It is responsible for the "fight or flight" response, increasing heart rate, dilating airways, and mobilizing energy stores, in contrast to the parasympathetic system's role in promoting relaxation and digestion.
parasympathetic and sympathetic nervous systems
Yes, coronary vessels have both parasympathetic and sympathetic innervation. Parasympathetic input leads to vasodilation of coronary vessels, while sympathetic input can cause vasoconstriction in response to stress or exercise. The balance between these two systems helps regulate blood flow to the heart.
No, parasympathetic postganglionic axons secrete the neurotransmitter acetylcholine, not norepinephrine. Norepinephrine is the primary neurotransmitter used by postganglionic neurons of the sympathetic nervous system.
The sympathetic and the parasympathetic nervous systems work together to maintain in a balanced state of homeostasis. The sympathetic takes care of the arousal and the parasympathetic handles the calming.
The parasympathetic and sympathetic divisions of the autonomic nervous system or antagonistic. They have opposing effects.

The sympathetic division as it can override the parasympathetic, but not vice versaboth are antagonistic to each otherbut parasympethatic system decreases the rates of the reaction in most of the cases but the sympethatic system increase the rates of the reaction although both are antagonistic to each otherfor more informationdr.khizar matloob+923336333015
True
the ephinephrine is secreted from sympathetic or parasympathetic
Sympathetic
Parasympathetic activation tends to have opposite effects to sympathetic activation. This means that parasympathetic activation typically promotes "rest and digest" functions such as slowing heart rate, promoting digestion, and relaxing muscles, while sympathetic activation triggers the "fight or flight" response, increasing heart rate, dilating airways, and redirecting blood flow to muscles.
Sympathetic fibers convey impulses that stimulate our "fight or flight" response. Parasympathetic are just the opposite, you might say they are for "rest and digest". They are both firing at the same time but depending on your environment and emotional state, one will dominate over the other. Sympathetic and parasympathetic fibers release different neurotransmitters, which bind to different receptors. Three structures that receive sympathetic innervation are the adrenal glands, arrector pilli muscles, and sweat glands.
sympathetic
The vagus nerve is parasympathetic.
The two divisions of the autonomic nervous system (ANS), the sympathetic and parasympathetic divisions, typically have opposing functions. The sympathetic division is responsible for the "fight or flight" response, while the parasympathetic division promotes the "rest and digest" response. They work together to maintain balance and regulate bodily functions.
