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.
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

...sympathetic nervous system. When faced with a threat, this system triggers a series of physiological changes to prepare the body to either confront the danger or flee from it. Key components of the fight or flight response include increased heart rate, heightened senses, and the release of stress hormones like adrenaline.
Response to acute pain is made by the sympathetic nervous system (the nerves responsible for the fight-or-flight response of the body).
Parasympathetic nervous system (flight or fight response)
The components of the SNS (Sympathetic Nervous System) include nerve fibers originating in the thoracic and lumbar regions of the spinal cord, neurotransmitters such as norepinephrine, adrenergic receptors on target tissues, and the fight or flight response it elicits in the body.
The fight or flight response is coordinated by a part of the brain called the amygdala, which is responsible for emotional processing and memory. It triggers the release of stress hormones like adrenaline to prepare the body for action in response to perceived threats. Additionally, the hypothalamus and the autonomic nervous system play crucial roles in initiating the physiological changes associated with fight or flight.
The Sympathetic and Parasympathetic nervous systems are the divisions of the ANS. The sympathetic is where "fight or flight" comes in, and the parasympathetic is what calms us down afterward -- they work to balance each other.
