yes, the heart has its own pacemaker. The autonomic nervous system, while it can effect the heartbeat, cannot initiate it. That's the job of the Sinoatrial node located in the right atrium. It triggers an electrical impulse that travels down the right atrium, between the ventricles, and up the sides of the heart. This electrical impluse is what causes the heart to beat.

Most people just are nervous of what other people think also they could just have stage fright.
Could you survive without platelets?
The platelets help to stem bleeding. Without them, it may be difficult to stop bleeding from a wound.
Is the heart apart of the circulatory system?
The heart is not considered a part of the digestive system. However you do have to remember that all organ systems are very inter-connected. For example, nutrients that diffuse through the walls of the the small intestine go directly into the bloodstream and are transported the the appropriate part of the body. That blood is pumped by the heart. The organs that are directly involved in digestion, like the stomach or liver, could not stay alive without the constant pumping of blood by the heart. Without the heart, digestion could not occur. On that same token, digestion could not take place without the brain, or the lungs. However neither the heart, the brain, nor the lungs are considered a part of the digestive system.
Where can someone find the definition for Autonomic Nervous System?
Someone can find the definition of the Autonomic Nervous System in libraries. They could also ask a scientist for the definition, they could help you figure out everything you need to know about the Autonomic Nervous System.
What nervous system is responsible for the involuntary processes of the human body?
You are probably referring to "involuntary body functions" - and the answer would be the autonomic nervous system. This system could be further divided into the sympathetic nervous system and the parasympathetic nervous system.
Is the autonomic nervous system under conscious control?
The nervous system controls many things, almost everything in our bodies. Here is a list that probably could be much longer:BehaviorCognitionMemoryEmotionsMetabolismHomeostasisDigestionRespirationHeart rateBlood pressureand much more...
What part of the nervous system controls all body activities?
The central nervous system is the part of the nervous system that controls all body activities, but it could not work without the peripheral nervous system.
How many cells in a nervous system?
You could say there are 2, The Central Nervous System(CNS), & the Peripheral Nervous System (PNS).To be more inclusive, here is a list of human nervous systems:The Central Nervous System (CNS), the Peripheral Nervous System (PNS),the Somatic Nervous System (SNS), the Autonomic Nervous System, the Sympathetic Nervous System, and the Parasympathetic Nervous System.That would make a total of 6, although the Sympathetic and Parasympathetic are parts of the Autonomic Nervous system, which could mean a total of 4, and the Autonomic is itself a part of the Peripheral Nervous System, which would bring the total back to 2.The Central Nervous System is comprised of the brain and the spinal cord;the Peripheral Nervous System connects the CNS to other parts of the body, and is comprised of the Somatic Nervous System and the Autonomic Nervous System;the Somatic Nervous System includes all the nerves controlling the body's muscular system, and sensory nerves;the Autonomic Nervous System consists of motor neurons which control internal organs, and is comprised of two sub-systems, the Sympathetic Nervous System, and the Parasympathetic Nervous System;the Sympathetic Nervous System is involved in the fight-or-flight response, and the Parasympathetic Nervous System is involved in relaxation.
What are the four parts of the nervous system?
You could define the 5 major parts of the nervous system by saying they are:the central nervous system, and the somatic, sympathetic, parasympathetic and entericnervous systems.However, a better way of describing the parts of the nervous system is todivide it into two main parts and then sub-parts:the main parts:the Central Nervous System (CNS, brain & spine),and the Peripheral Nervous System (PNS, all the nerves and neurons outside the brain and spine).Then the peripheral nervous system is divided intothe somatic nervous system (nerves which control the voluntary muscles) andthe autonomic nervous system (nerves which control visceral functions or organs like the heart or stomach);and the autonomic nervous system is itself divided into thesympathetic (fight-or-flight emergency response),parasympathetic (relaxation),and enteric (digestive) nervous systems.
Could any other body system function without the nervous system?
Perhaps the heart would continue to pump as it has cells that "beat" on their own without any nervous stimulation.
How could damage to the nervous system affect another body system?
none of the other body systems could function without direction from the nervous system or energy provided by the digestive and circulatory systems.

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.
What organ system reacts to stimuli?
The respiratory system is responsible for bringing gases into and out of the body. It could not perform this exchange, however, without the circulatory system.
What nervous system function contributes to thinking?
The nervous system functions do not form thoughts but it could contribute to them. Arousal, which is a nervous system function, could lead to desire.
