Sympathetic Nervous System


What neurotransmitter is used by most postganglionic sympathetic neurons?

At the effector end (nerve to effector organ junction) the transmitter is Nor Adrenaline. However, at the nerve-nerve junctions (ganglions) the transmitter is Acetyl Choline.


How does the autonomic nervous system regulate the body's response to stress, specifically through the activation of the sympathetic or parasympathetic branch?

The autonomic nervous system helps the body respond to stress by activating either the sympathetic or parasympathetic branch. The sympathetic branch triggers the "fight or flight" response, increasing heart rate and releasing stress hormones. The parasympathetic branch helps the body relax after stress, slowing heart rate and promoting digestion.


Is the autonomic nervous system primarily sympathetic or parasympathetic in its function?

The autonomic nervous system has two main branches: sympathetic and parasympathetic. The sympathetic branch is responsible for the "fight or flight" response, while the parasympathetic branch is responsible for the "rest and digest" response. Both branches work together to maintain balance in the body's functions.


When the sympathetic branch is activated?

When the sympathetic branch is activated, it initiates the body's fight-or-flight response by increasing heart rate, dilating the airways, and releasing stress hormones like adrenaline. This response helps the body prepare to deal with perceived threats or dangers.


What are the major components in the Autonomic nervous system?

The basic components of the ANS are the sympathetic and parasympathetic branches. The sympathetic branch, or SNS, is responsible for the flight-or-fight response and the parasympathetic, or PNS, is called the rest-and-digest system.parasympathethic and sympathetic nervous system


What are sympathetic nerve paths?

Sympathetic nerve paths are part of the sympathetic nervous system, which is responsible for the body's "fight or flight" response. These nerve pathways originate in the spinal cord and branch out to various organs and tissues in the body to help respond to stress or danger by increasing heart rate, dilating pupils, and redirecting blood flow.


These physical reactions are triggered by what system?

These physical reactions are triggered by the autonomic nervous system, which controls involuntary bodily functions such as heart rate, digestion, and respiration. The sympathetic branch of the autonomic nervous system is responsible for the "fight or flight" response, while the parasympathetic branch helps the body to relax and recover.


What is flow transmitter?

pressure transmitter


When blood pressure falls which branch of the autonomic nervous system will become active?

Low blood pressure is an abnormal, and dangerous condition that triggers the bodies "fight or flight" reaction. This is regulated by the sympathetic branch of the nervous system.
