sympathetic nervous system.
The sympathetic nervous system originates in the spinal cord and its main function is to activate the physiological changes that occur during the fight-or-flight response.
The hypothalamus and the sympathetic nervous system are primarily associated with the general adaptation syndrome. The hypothalamus initiates the stress response, while the sympathetic nervous system activates fight-or-flight reactions in response to stress.

sympathetic nervous system.
The autonomic nervous system, particularly the sympathetic and parasympathetic branches, regulates physiological changes that accompany an emotional response. The sympathetic nervous system is responsible for the "fight or flight" response by increasing heart rate, dilating pupils, and releasing adrenaline, while the parasympathetic nervous system helps return the body to a state of rest and relaxation after the emotional response subsides.
The sympathetic nervous system still allows us to have a fight or flight response, but it can also lead to an excessive stress response.
Sympathetic inhibition refers to a decrease in the activity of the sympathetic nervous system, which is responsible for the fight-or-flight response. This can result in a decrease in heart rate, blood pressure, and overall stress levels in the body. Sympathetic inhibition is often associated with relaxation, rest, and recovery.
Sympathetic nervous system response/ baroreceptor response
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 sympathetic division of the autonomic nervous system controls the fight or flight response. This response triggers physiological changes that prepare the body to either confront or escape from a threatening situation, such as increased heart rate, dilated pupils, and enhanced alertness.
