It is perhaps best known for mediating the neuronal and hormonal stress response commonly known as the fight-or-flight response.
What responses does the sympathetic nervous system produce?
sympathetic nervous system, division of the nervous system that functions to produce localized adjustments (such as sweating as a response to an increase in temperature) and reflex adjustments of the cardiovascular system.
What is an example of a sympathetic response?
The sympathetic nervous system directs the body’s rapid involuntary response to dangerous or stressful situations. A flash flood of hormones boosts the body’s alertness and heart rate, sending extra blood to the muscles.
What does the sympathetic nervous system control quizlet?
The sympathetic nervous system arouses the body and expends energy. It is responsible for our fight and flight response.
Which of the following is an action of the sympathetic nervous system quizlet?
The sympathetic nervous system increases arousal of the muscles, organs and glands and prepares the body for vigorous activity. Arouses us for defensive action. Pupils dilate, heart accelerates, bladder constricts, lungs increase, adrenal glands release adrenalin, stomach decreases contractions.
Is an example of a sympathetic response quizlet?
An example of a sympathetic response can be pupillary dilation, increased heart rate, increase in blood pressure, dilation of blood vessels, and an increase in glucose production.
What is sympathetic with examples?
The definition of sympathetic is feeling compassion for someone or a situation, or connected by a mutual feeling or passion. An example of sympathetic is a person who feels badly for a friend who lost her job.
What is the function of the sympathetic nervous system quizlet psychology?
The sympathetic nervous system’s role is to stimulate the “fight or flight” response. It does so by accelerating heart rate and respiration, increasing muscle blood flow and tension, dilating pupils and suppressing digestion.
When your sympathetic nervous system is activated you quizlet?
When the Sympathetic Nervous System is triggered, glycogen is broken down to glucose to provide more energy. The Parasympathetic Nervous System is triggered to act by exposure to epinephrine. You just studied 25 terms!
When the sympathetic system is activated which of the following occur?
In the heart (beta-1, beta-2), sympathetic activation causes an increased heart rate, the force of contraction, and rate of conduction, allowing for increased cardiac output to supply the body with oxygenated blood.
Which response would be expected from stimulation of the sympathetic nervous system quizlet?
When stimulated, the sympathetic nervous system prepares the body to flee or to turn and fight (Figure 29.3). Cardiovascular activity increases, as do blood pressure, heart rate, and blood flow to the skeletal muscles.
Which of the following are controlled by the autonomic nervous system quizlet?
Autonomic nervous system controls smooth muscle, cardiac muscle, and glands.
Which is the following is a function of the nervous system?
The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.
What stimulates the sympathetic nervous system quizlet?
Epinephrine stimulates the sympathetic nervous system in response to mental stress or physical injury.
What are the functions of sympathetic and parasympathetic nervous system?
The sympathetic system controls “fight-or-flight” responses. In other words, this system prepares the body for strenuous physical activity. The events that we would expect to occur within the body to allow this to happen do, in fact, occur. The parasympathetic system regulates “rest and digest” functions.
Which action belongs to the sympathetic division of the nervous system quizlet?
General responses to increase sympathetic activity include heightened mental alertness, increased metabolic rate, reduced digestive and urinary functions, activation of energy reserves, increased respiratory rate and dilation of respiratory passageways, elevated heart rate and blood pressure, and activation of sweat …
What activity would likely activate the sympathetic nervous system the most?
The correct answer is c) Weeping at a funeral. The sympathetic nervous system excites us whereas the parasympathetic nervous system calms us.
What effect does the sympathetic nervous system have on attention?
What effect does the sympathetic nervous system have on attention? The sympathetic nervous system helps an individual to focus attention on one item at a time.
What is the effect of sympathetic nerve stimulation quizlet?
sympathetic nerve stimulation increases heart rate.
Which of the following is an effect of the sympathetic nervous system stimulation quizlet?
Sympathetic nervous system stimulation causes vasoconstriction, thereby elevating blood pressure.
Which of the following does not occur with stimulation of the sympathetic nervous system quizlet?
Stimulation of the sympathetic nervous system results in all of the following EXCEPT: Decreased rate of cellular metabolism.
Which of the following will result from sympathetic stimulation?
Stimulation by the sympathetic system nerves results in an increase of heart rate, as occurs during the “fight-or-flight” response.
Which best describes autonomic nervous system control?
The correct answer is (c) Controls and maintains homeostasis. The autonomic nervous system consists of the sympathetic and parasympathetic nervous systems, which control the unconscious processes that help maintain homeostasis, or stable, internal conditions.
What’s the difference between parasympathetic and sympathetic nervous system?
The autonomic nervous system comprises two parts- the sympathetic and parasympathetic nervous systems. The sympathetic nervous system activates the fight or flight response during a threat or perceived danger, and the parasympathetic nervous system restores the body to a state of calm.
What are the 3 major functions of the nervous system?
First, the basic functions of the nervous system are sensation, integration, and response. Secondly, control of the body can be somatic or autonomic—divisions that are largely defined by the structures that are involved in the response.
