What else can I help you with?
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.

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 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 describes the autonomic nervous system?
The autonomic nervous system controls involuntary bodily functions like heart rate, digestion, and breathing. It is divided into the sympathetic and parasympathetic nervous systems, which work in opposition to regulate different physiological responses.
What does the voluntary nervous system control?
the somatic system control everything
What are the similarities between the autonomic nervous system and the somatic nervous system?
The two are made up of nerves, and they work together as a system, so together they are said to comprise the overall nervous system.The Central Nervous System (CNS) is the command center for the body; the Peripheral Nervous System (PNS) provides the CNS with sensory information, and also conveys activation signals to muscles from the CNS to help the organism move and survive.
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 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.
