The effects of the sympathetic nervous system are essentially opposite of which nervous system?
The effects of the sympathetic nervous system are essential opposite those of the parasympathetic nervous system. The sympathetic nervous system accelerates functions such as heart rate and breathing and the parasympathetic slows these bodily processes down. The sympathetic also inhibits digestion, whereas the parasympathetic stimulates digestion. The sympathetic nervous system produces "fight-or-flight" reactions, while the parasympathetic functions under relaxed conditions.
Does the autonomic nervous system may cause activation or inhibitiom depending on the division that is active and the target that is affected?
Yes, the autonomic nervous system can cause either activation or inhibition depending on whether the sympathetic division or parasympathetic division is active, and which target organ is being affected. The sympathetic division generally activates the fight-or-flight response while the parasympathetic division promotes rest and relaxation.
Which has more specific local control the sympathetic or parasympathetic division of the autonomic nervous system?
The sympathetic division of the autonomic nervous system typically has more specific local control. This is because sympathetic nerves release norepinephrine at specific target tissues, allowing for precise modulation of target organ responses. In contrast, the parasympathetic division releases acetylcholine more diffusely, leading to more widespread effects on multiple target organs.
How can sympathetic and parasympathetic fibers act as antagonists?
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.
Dual innervation refers to an organ receiving?
Dual innervation refers to an organ receiving input from both the sympathetic and parasympathetic divisions of the autonomic nervous system. This allows for precise regulation of the organ's function by balancing the effects of these two opposing systems. Examples include the heart receiving both sympathetic stimulation (increasing heart rate) and parasympathetic stimulation (slowing heart rate).
What is between the sympathetic and the parasympathetic nervous system?
The parasympathetic and sympathetic divisions of the autonomic nervous system or antagonistic. They have opposing effects.

The effects of sympathetic and parasympathetic stimulation of the salivary glands are called?
complementary
The separate effects of sympathetic and parasympathetic innervation of the pacemaker region of the heart can best be described as?
antagonistic

Yes, the autonomic nervous system can cause either activation or inhibition depending on whether the sympathetic division or parasympathetic division is active, and which target organ is being affected. The sympathetic division generally activates the fight-or-flight response while the parasympathetic division promotes rest and relaxation.
Does the sympathetic and parasympathetic nerves work in opposite directions to balance each other?
Yes, the sympathetic and parasympathetic nervous systems have opposing effects to help maintain homeostasis in the body. The sympathetic nervous system activates the "fight or flight" response, while the parasympathetic nervous system triggers the "rest and digest" response. Together, they work in balance to regulate various bodily functions.
Which has more specific local control the sympathetic or parasympathetic division of the autonomic nervous system?
The sympathetic division of the autonomic nervous system typically has more specific local control. This is because sympathetic nerves release norepinephrine at specific target tissues, allowing for precise modulation of target organ responses. In contrast, the parasympathetic division releases acetylcholine more diffusely, leading to more widespread effects on multiple target organs.
How can sympathetic and parasympathetic fibers exert antagonistic effects?
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.
What effects would the sympathetic and parasympathetic system have on insulin secretion?
The sympathetic system tends to inhibit insulin secretion, as it is involved in the "fight or flight" response where energy is needed quickly. On the other hand, the parasympathetic system stimulates insulin secretion, as it is known as the "rest and digest" system that promotes nutrient absorption and storage.

Why does the sympathetic division of the ANS have a more widespread and longer lasting effects than the parasympathetic division?
That may seem possible from illustrations, but in actuality the role of homeostasis is to have both systems functioning equally to maintain balance in the body systems. 1. After parasympathetic fibers secret acytelcholine it is quickly broken down by acytelcholinesterase, which makes parasympathetic effects only a few seconds long.
