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.
What else can I help you with?
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.
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 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.
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
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.
List the division of the autonomic nervous system?
the autonomic nervous system (ANS) includes the peripheal nerves and ganglia on either side of the spinal cord ( note: some textbooks include the ANS as a division pf the peripheal nervous system both ways are correct.)
In general parasympathetic activation will produce effects that are to those produced by activation of sympathetic neurons?
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.
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.
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.
The autonomic nervous system contains two branches called the?
The autonomic nervous system also has two divisions: the sympathetic division and the parasympatheticdivision. These two divisions have antagonistic (opposing) effects on the internal organs they innervate (send nerves to act on).The sympathetic division, shown at the left, is the emergency system. It prepares the body to put out energy and to protect it from effects of injury. It shuts the gut down, speeds up the heart, increases blood pressure, dilates (makes bigger) the pupils of the eyes, makes more glucose (blood sugar) available in the blood for energy, etc. Cannon described these reactions as preparation for fight or flight (running away).The parasympathetic division, shown at the right, is the "housekeeping" division. It acts to replace and recover from the activities of living. Its action is (almost always) the opposite of the sympathetic division. It activates the gut for digestion, slows the heart rate, decreases the blood pressure, etc.
