The autonomic nervous system also has two divisions: the sympathetic division and the parasympatheticdivision. These two divisions have antagonistic (opposing) effects on the internal organs they innervate (send nerves to act on).
The sympathetic division, shown at the left, is the emergency system. It prepares the body to put out energy and to protect it from effects of injury. It shuts the gut down, speeds up the heart, increases blood pressure, dilates (makes bigger) the pupils of the eyes, makes more glucose (blood sugar) available in the blood for energy, etc. Cannon described these reactions as preparation for fight or flight (running away).
The parasympathetic division, shown at the right, is the "housekeeping" division. It acts to replace and recover from the activities of living. Its action is (almost always) the opposite of the sympathetic division. It activates the gut for digestion, slows the heart rate, decreases the blood pressure, etc.

∙ 11y agoThe 2 functional components of the peripheral nervous system include:
- The Somatic Nervous System that sends motor innervation to skeletal muscles and from skin and somatic tissues.
- The Autonomic Nervous System that innervates smooth muscle, blood vessels and viscera. The 2 divisions of the autonomic nervous system include the sympathetic and parasympathetic nervous systems.
The peripheral nervous system contains many nerves that originate from the brain, brainstem, and spinal cord. These nerves can be divided into:
- Cranial nerves that exit the cranium but originate from the brain, brainstem, or upper spinal cord.
- Spinal nerves that originate from the spinal cord and exit neural foramina in the spine.

∙ 14y agoDo you mean the network of sensory and motor nerve fibers that spread out thru the whole body, this comes from the Central Nervous System which controls all basic body functions responds to keep body temperature even..... which is also a form of homeostasis

The system of the nerves that work automatically is called what?
The Autonomic Nervous System.
What part of the brain is responsible for helping you run and catch the bus?
That part is called as hypothalamus. It is supposed to be highest centre for the autonomic nervous system. You need the sympathetic nervous system to run and catch the bus. Sympathetic nervous system is the part of the autonomic nervous system.

Sympathetic
The Motor Division of the peripheral nervous system is divided into two functional divisions called the what and what nervous system?
The sympathetic and the parasympathetic divisions of the autonomic nervous system.
What nervous system is a division of the peripheral nervous system that deals with involuntary movement of smooth and cardiac muscles?
That system is called as autonomic nervous system. It is composed of sympathetic and parasympathetic nervous systems.
What is the third part of the nervous system called?
Autonomic nervous system
Branches that sometimes occur along the length of an axon are called what?
Collaterals are branches that sometimes occur along the length of an axon. Parasympathetic branch is the branch of the autonomic nervous system causes increased secretion by digestive glands.
What is the functions of the autonomic nervous system?
The involuntary nervous system that is involved with organ regulation is called the Autonomic nervous system (ANS) and is comprised of the Sympathetic nervous system and the Parasympathetic nervous system.
The system of the nerves that work automatically is called what?
The Autonomic Nervous System.
What is another name for the visceral motor nervous system?
Another name for the autonomic nervous system (ANS) is the visceral nervous system.& u can also called it vegetal nervous system....
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
The part of the autonomic nervous system that is responsible for reacting to stressful events and bodily arousal is called?
The sympathetic nervous system
