autonomic nervous system refers to visceral organs that we are unable to control. these organs control actions such as breathing, heart rate, etc. that occur without having to be thought about

Is the sympathetic nervous system same as central nervous system?
Autonomic nervous system is that part of the nervous system that controls the body function that are not consciously controlled by the human brain like breathing, heartbeat, and digestive processes. Autonomic nervous system is a part of the peripheral nervous system. It works along with the somatic nervous system to regulate the body functions.
How does your smooth muscles benefit you?
They are responsible for digestion. They are also part of the autonomic nervous system, so you do not have to consciously control them.
What is the function of the autonomic nervous system?
The function of the autonomic nervous system is to control involuntary actions, or body functions that must operate even without conscious awareness of those functions. It regulates heart activity, acting like brakes and accelerators to decrease or increase the heart rate.
What division of the autonomic nervous system mediates the reflex release of saliva?
The parasympathetic nervous system stimulates salivary gland secretion, and accelerates peristalsis, so, in keeping with the rest and digest functions, appropriate PNS activity mediates digestion of food and indirectly, the absorption of nutrients. Source: Wikipedia: http://en.wikipedia.org/wiki/Autonomic_nervous_system enteric nervous system is responsible for the pupillary light reflex
Why is it so important for the cardiac muscles to be controlled by the autonomic nervous system?
Since continuous blood flow is necessary to keep us alive, if the cardiac muscles were NOT controlled by the autonomic nervous system, we would die as soon as we fell asleep and quit thinking about making the muscle move. Sweet Dreams...
What describes the autonomic nervous system?
The nervous system (NS) can be divided into the central nervous system (CNS) which is the brain and spinal cord and the peripheral nervous system (PNS) which is the rest of the body. One of the general functions of the NS is Motor function. Motor function uses peripheral neurons so this particular function belongs to the PNS. Motor functions can be divided into two categories: (1) As motor functions of the Somatic Nervous System and (2) as motor functions of the Autonomic Nervous System. The Somatic nervous system is voluntary and controls skeletal muscle. The autonomic nervous system, or ANS, is that part of the peripheral nervous system that is involuntary. The ANS controls and regulates smooth muscle, cardiac muscle and glands. Most neuron axons in the ANS are unmyelinated and myelinated axons are rare. It's not possible to describe the ANS without also describing the SNS and mentioning at least one of the functions (Motor function)of the nervous system. You need to see how they all fit together.
What body parts make up of the nervous system?
Depending on what nervous system you are talking about and how complicated you want to get, there can be many answers. In the central nervous system it is comprised of the brain and spinal cord. The Peripheral nervous system is comprised of everything outside of that... so that means all of your nerves and such going to and from sensory and motor locations of the body. there are two more divisions of the peripheral nervous system. autonomic and somatic nervous systems The autonomic includes heart and breathing an stuff like that. Somatic is divided once more into sympathetic and parasympathetic which controls the rest of everything that is happening.
What does the parasympathic nervous system do?
Parasympathetic is a subcategory of autonomic in CNS. They used to said that Parasympathetic control "rest" and "digest" . So whatever activities deal w/ those 2 conditions, you can tell it is controlled by the parasympathetic Nervous system
What does the voluntary nervous system control?
the somatic system control everything
Do all nerves have a myelin sheath?
Some nerve cells are unmyelinated, specially from autonomic nervous system. Why it is so, is not clear to the contributor. Expert comment is needed on this topic.
What are the two main divisions of the nervous system and what makes up both of them?
Anatomical Divisions are the... CNS (central nervous system) which consists of the brain and spinal cord. the cns is the bodys neural control center, it receives incoming info (impulses), analyzes and organizes it, and initiates appropriate action. PNS (peripheral nervous system) which is located outiside of the CNS and consists of nerves and sensory receptors, the PNS carries impulses formed by receptors, such as pain and sound receptors, to the CNS and it carries impulses from the CNS to effectors, glands and muscles that carry out actions directed by the CNS Functional Divisions are... Sensory division which carries impulses from sensory receptors to the CNS Motor division , which carries impulses from the CNS to effectors the motor division can also be divided into the SNS (somatic nervous system) which is involved in the voluntary control of the skeletal muscles ANS (autonomic nervous system) which is involved in the involuntary control of cardiac muscle, smooth muscle and glands
What system or systems are involved in neurological disorders?
Neurological disorders affect the nervous system which is divided into two parts, the autonomic nervous system and the somatic nervous system. They are spread throughout the entire body and relate to many other systems such as the digestive system, heart rate and sexual arousal. Because these systems are so intertwined a neurological disorder could affect multiple body systems.
