Which effect could result from activation of the sympathetic nervous system?

What happens when sympathetic nervous system is activated?

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 of the following effects would result from activation of the sympathetic nervous system?

For example, the sympathetic nervous system can accelerate heart rate, widen bronchial passages, decrease motility of the large intestine, constrict blood vessels, increase peristalsis in the esophagus, cause pupillary dilation, piloerection (goose bumps) and perspiration (sweating), and raise blood pressure.

What is an effect of the sympathetic nervous system quizlet?

The sympathetic nervous system helps regulate body temperature in three ways: *By regulating blood flow to the skin, sympathetic nerves can increase or decrease heat loss. By dilating surface vessels, sympathetic nerves increase blood flow to the skin and therby accelerate heat loss.

What triggers sympathetic nervous system?

After the amygdala sends a distress signal, the hypothalamus activates the sympathetic nervous system by sending signals through the autonomic nerves to the adrenal glands. These glands respond by pumping the hormone epinephrine (also known as adrenaline) into the bloodstream.

How does the sympathetic nervous system affect blood pressure quizlet?

The sympathetic nervous system will activate an increase in blood pressure by increasing the heart rate, causing the heart to contract more forcefully and constricting some blood vessels, which increases the resistance of vessels.

What effect does the sympathetic nervous system have on digestive processes?

In general, sympathetic stimulation causes inhibition of gastrointestinal secretion and motor activity, and contraction of gastrointestinal sphincters and blood vessels. Conversely, parasympathetic stimuli typically stimulate these digestive activities.

Is lacrimation sympathetic or parasympathetic?

A useful acronym to summarize the functions of the parasympathetic nervous system is SLUDD (salivation, lacrimation, urination, digestion, and defecation). The parasympathetic nervous system may also be known as the parasympathetic division.
