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.
What else can I help you with?
The Motor Division of the peripheral nervous system is divided into two functional divisions called the what and what nervous system?
The Motor Division is divided into the Somatic and Autonomic Nervous System. The Somatic Nervous System controls voluntary movements of skeletal muscles, while the Autonomic Nervous System regulates involuntary functions like heart rate and digestion.
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.
The system of the nerves that work automatically is called what?
The system of nerves that work automatically is called the autonomic nervous system (ANS). It regulates involuntary bodily functions such as heart rate, digestion, and sweating. The ANS consists of two main divisions: the sympathetic nervous system and the parasympathetic 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 does the autonomic nervous system direct?
The autonomic nervous system is the system by which the body controls the processes required to survive that happen without the body having to think about them. This includes processes such as breathing, digestion, heart rate and salivation.
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 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

What is the first motor neuron in an autonomic pathway called?
The first motor neuron in an autonomic pathway is called a preganglionic neuron. It originates in the central nervous system and synapses with a postganglionic neuron in an autonomic ganglion.
The system of the nerves that work automatically is called what?
The system of nerves that work automatically is called the autonomic nervous system (ANS). It regulates involuntary bodily functions such as heart rate, digestion, and sweating. The ANS consists of two main divisions: the sympathetic nervous system and the parasympathetic nervous system.
The division of the autonomic nervous system that controls the series of physiological responses that are collectively called the rest-and-digest response?
parasympathetic nervous system
What is the functions of the autonomic nervous system?
