How do the sympathetic and parasympathetic nervous systems operate antagonistically in emotional responses?

One system creates an emotional response, and the other dampens it. The sympathetic nervous system creates a short-term mobilizing response, and the parasympathetic nervous system dampens it in the long term.

Describe the meaning and importance of sympathetic tone and parasympathetic tone?
Both your sympathetic and parasympathetic neurons have a constant rate of firing under normal conditions. This is called their "tone", and it maintains the normal rate of your heartbeat, keeps your blood pressure within a normal range and such to maintain homeostasis. Of course, the sympathetic and parasympathetic firing rate changes greatly during fight-or-flight responses and such.
What does adrenergic mean?
Adrenergic-- Activated by adrenalin (norepinephrine), loosely applied to the sympathetic nervous system responses.
Why is it that when you cry mucous secretions coming from the nose are also present?
When you cry, your lacrimal glands produce tears. These tears drain into the nasolacrimal duct, which is connected to your nose. As a result, the excess tears can enter your nasal cavity, causing an increase in mucous secretions and leading to a runny nose. This is a normal physiological response to emotional or physical distress.
When dealing with a life crisis what are the five emotional responses?
The five standard emotional responses to a life crisis are: 1) Denial 2) Anger 3) Bargaining 4) Depression 5) Acceptance These may not occur in order or may happen multiple times.
What are alpha receptor antagonists?
If they are also known as alpha-adrenergic blocking drugs (i'm not sure if they are), then they prevent norepinephrine from producing sympathetic responses.

Are sweat glands parasympathetic or sympathetic?
They are sympathetic but an exception - ACh is released as a post-synaptic neurotransmitter rather than Adrenaline/Noradrenaline.Illicitinga parasympathetic response will not stimulate these neurons and therefore sweating is not a parasympathetic side effect.However, as post-synaptic sweat glands contain Muscarinic receptors and not adrenoceptors the administration of a non-selective Muscarinic agonist would result in both a parasympathetic response such as constriction of the pupil or decreased heart rate as well as sweating due to the activation of these sympathetic post-synaptic MAChR in the sweat glands.Atropine would reduce all parasympathetic responses and stop sweating.
Initiates the rest-and-digest or feed-and-breed responses?
Parasympathetic
Responsibility of the autonomic nervous system?
All the unvoluntary things.... You have the parasympathetic nervous and the sympathetic nervous system. Parasympathetic nervous system: Long pre-g, short post-g aka the craniosacral nervous system - The slow responses.... like slow heart rate by vagus nerve Sympathetic nervous system: Short preg-, long post-g aka the thoracolumbar nervous system - Fight or flight responses like increase heart rate . Pre-g nicotinic stimulation to adrenal medulla which releases adrenaline (epinephrine)
Is the parasympathetic system controls the fight or flight responses?
The Parasympathetic Division is in charge of "rest and digest" and has a calming effect on many body functions. The sympathetic division is in charge of the "fight or flight" increasing breathing rate allowing more oxygen intake, and increase of heart rate allowing more blood to flow throughout body.
Explain the difference between sympathetic and parasympathetic reactions as they occur in the autonomic nervous system?
The sympathetic nervous system is most active when you are in an emergency, exercising, or an exciting or embarrassing situation. It is often referred to as the "fight-or-flight" system. It increases the heart rate, blood pressure, and blood glucose levels. It also dilates the bronchioles of the lungs, and dilates the blood vessels of the skeletal muscles. This nervous system enables the body to cope rapidly with situations. The parasympathetic nervous system is active when the body is resting. It is referred to as the "resting-and-digesting" system. It conserves your body's energy by slowing the heart rate. It also promotes digestion.sypmathetic is the "fight or flight" response and the parasympathetic is the "rest and digest" responses
Why are sympathetic responses generally widespread?
Sympathetic responses are more widespread because of the way the efferent nerves (from spinal cord outward) are positioned. The autonomic system has two neurons between its spinal cord and the organ that it is modulating whereas the somatic system has only one. The difference between the sympathetic and the parasympathetic is that in the case of sympathetic, the first nerve out of the spinal cord, called the preganglionic fiber is extremely short and ends relatively close to the spinal cord. Here, the preganglionic fiber synapses with on average of 10 postganglionic fibers which then moves onto effect a variety of different organs. On the other hand, in the parasympathetic division the preganglionic nerve are extremely long and extends until it is almost at the organ. From there, it synapses with a very short post-synaptic nerve that then synapses an organ. The ratio in this case can be about 1:3 but usually is 1:1. To sum things up, in the sympathetic division, the preganglionic fiber terminates very early and therefore has the "opportunity" to interact with a variety of nerves. On the other hand, the parasympathetic division has such a long preganglionic fiber that by the time it synapses its post ganglionic fiber, it is pretty much at the organ. NE and epinephrine are secreted into the blood as part of the sympathetic response.
Does the hypothalamus control emotional responses?
Yes
What is the division of the autonomic nervous system that controls the series of physiological responses that are called rest-and-digest?
Parasympathetic.
Are the the thermoregulatory responses to increased heat are mediated by the sympathetic nervous division?
yes
What has the author Emily M Masson-Guipe written?
Emily M Masson-Guipe has written: 'The effects of exercise training on sympathetic and parasympathetic nervous system responses to a novel stressor in Sprague-Dawley rats' -- subject(s): Zoology, Rats, Cardiovascular system, Exercise, Physiological aspects
What do the nerves in the autonomic nervous system do?
The autonomic system regulates contraction and secretion within the body.It regulates/controls:cardiac and smooth musclesecretions of the exocrine glandit controls some endocrine secretionsit controls some adipose tissue
