The nervous system consists of three main nerve types. Sympathetic nervous system. Our nervous system consists of three nerve types: sensory nerves, motor nerves, and autonomic nerves. Two functions: 1. Sensory nerves supply humans with the ability to see, hear, smell, taste and feel. Counterbalancing the activities of the sympathetic nervous system after fight or flight response (calming down).

2. Motor nerves allow our brain to command and order our muscles to move (or not move). It controls the sex organ known as the penis . Autonomic nerves help regulate our internal organs and how they function. The sympathetic nervous systems stimulate the adrenal glands triggering the release of catecholamines, which include adrenaline and noradrenaline. The sympathetic nervous system (SNS) is a part of the autonomic nervous system (ANS) which is that part of the nervous system which controls most of our automatic bodily functions. Sensory nerves allow us to hear, see, smell, taste and feel. The sympathetic nervous system controls functions like increasing the heart rate and blood pressure, as well as slowing digestion. Keeps bodily systems functioning effectively in … Autonomic nerves regulate the function of the internal organs. The autonomic nervous system is the part of the nervous system that supplies the internal organs, including the blood vessels, stomach, intestine, liver, kidneys, bladder, genitals, lungs, pupils, heart, and sweat, salivary, and digestive glands.
The autonomic nervous system has two components, the sympathetic nervous system and the parasympathetic nervous system.

Now lets take a look at the Right Hemisphere of the brain. The central nervous system is the brain and spinal cord. It communicates with your central nervous system (CNS) which is comprised of your brain and spinal cord and also interacts with your immune system. The autonomic nervous system has two parts: the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system (SNS) can adjust circulatory, metabolic, and visceral activity depending on the postural and musculoskeletal demands. Sympathetic nervous system. The brain is the enlarged, head end of the central nervous system; it occupies the cranium, or brain case. In other words those that take place without us having to ‘think’ about them like pumping of the heart and breathing. It triggers the fight-or-flight response, providing the body with a burst of energy so that it can respond to perceived dangers.
It does this through the use of chemical nerve signals called neurotransmitters .

Author: Adrian Rad BSc (Hons) • Reviewer: Elizabeth Johnson PhD • Last reviewed: June 09, 2020 The autonomic system is made up of two divisions, the sympathetic and parasympathetic systems.They usually work antagonistically … Your stress response is linked to your autonomic nervous system (ANS), which is a part of your peripheral nervous system (PNS). Your ANS oversees vital and basic body functions such as blood sugar, breathing, heart rate, and blood pressure/blood flow..

What Happens During the Fight-or-Flight Response .

The sympathetic nervous system prepares the body for sudden stress, like if you witness a robbery.

Colloquially, the SNS governs the "fight or flight" response while the PNS controls the "rest and digest" …

When you look at the brain it is the Left Hemisphere that predominately controls this response.
