The sympathetic nervous system is the part of the autonomic nervous system originating in the thoracic and lumbar regions of the spinal cord that in general inhibits or opposes the physiological effects of the parasympathetic nervous system, as in tending to reduce digestive secretions, speeding up the heart, and contracting blood vessels.

∙ 13y agoThe sympathetic nervous system is part of the autonomic nervous system and it acts best described as "fight or flight". It stimulates your body into preparing itself against something.
You're autonomic response for sympathetic nervous system:
So your body senses the environment and that signal through your spinal cord and to your brain. Your brain identifies and figures out what it wants to do and sends out another signal out through the spinal cord and to the rest of your body. Within the spinal cord this area of nerves that correspond to the autonomic nervous system is called intermediolateral horn (IML). The afferent nerves have axonal varicosities which are areas where it releases neurotransmitters (more specifically norepinephrine) to the effector organ (which have adrenergic receptors, alpha 1, beta 1, beta2).
E.g. Somebody surprises and scares you. In response your heart rate will rise. This is a result of your body reaction to the sympathetic nervous system activating. The surprise will tell your brain that you need to get going and it activates the sympathetic nervous system. The effect of the sympathetic nervous system on the heart specifically, is that it increases heart rate.

How the endocrine system and nervous system work together when the body is under stress?
the endocrine and the nervous systems work together to maintain homeostasis
The sympathetic and parasympathetic nervous systems work together to maintain a balanced state called?
The sympathetic and the parasympathetic nervous systems work together to maintain in a balanced state of homeostasis. The sympathetic takes care of the arousal and the parasympathetic handles the calming.
Difference between parasympathetic and enteric nervous systems?
There really is no difference between these two levels of classification of the nervous system, but rather the parasympathetic and enteric division of the nervous system work with the sympathetic division to control smooth muscles, cardiac muscles, and glands in the body. They are both components of the autonomic nervous system.
What is the nervous system connected to?
The nervous system work very closelly to the endocrine system (hormones).
What two systems work with the muscular system?
The two systems that work with the muscular system is nervous system and circulatory system:) ur welcome
How does the sympathetic nervous system work for an against us in today's world?
The sympathetic nervous system still allows us to have a fight or flight response, but it can also lead to an excessive stress response.
The autonomic nervous system includes which of these major components?
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.
The system of nerves that work automatically is called?
the Autonomic nervous system, split into the sympathetic and parasympathetic divisions.
How the endocrine system and nervous system work together when the body is under stress?
the endocrine and the nervous systems work together to maintain homeostasis
Which has more specific local control the sympathetic or parasympathetic division of the autonomic nervous system?
The parasympathetic system has more control, as the sympathetic system includes hormonal effectors that work across the entire body.
While you are waiting to begin a foot race you can feel your heart rate go up. This is the at work.?
sympathetic nervous system
The sympathetic and parasympathetic nervous systems work together to maintain a balanced state called?
The sympathetic and the parasympathetic nervous systems work together to maintain in a balanced state of homeostasis. The sympathetic takes care of the arousal and the parasympathetic handles the calming.
How nervous system help maintain homeostatis?
The Nervous System has two separate control system the sympathetic and the parasympathetic stimulation. Both parts of the system work in opposition to each other. The sympathetic nervous system stimulates the heart, blood vessels, lungs and the metabolic system to prepare for the activity. The parasympathetic system is in control of rest and leisure periods, it also works to conserve energy. As you work out the sympathetic system takes over and act on both the heart and the release of hormones to stimulate the body into workout mode. The nervous system maintains homeostasis by sending signals to the brain and to the rest of the body.
Which of these endocrine glands produce hormones that work with the sympathetic nervous system and cause the fight or flight response?
adrenal glands!
Ito is on the swim team. When he is standing on the edge of the pool waiting to hear the starter gun his body is speeding up. This is the work of his system.?
