All the muscles of the heart are controlled by the nervous system.

No, most cardiac muscles are not directly controlled by the nervous system. The cardiac muscles have their own intrinsic pacemaker called the sinoatrial (SA) node that generates electrical impulses and coordinates the contraction of the heart. While the nervous system can influence the rate and strength of the heart's contractions, it does not have direct control over the cardiac muscles.

What muscles are controlled by the autonomic nervous system and operate the internal organs?
Smooth muscles
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 controlled by the somatic division of the PNS?
Somatic nervous system
What body system allows your body's movement?
Muscles.
The portion of the nervous system that most closely associated with the contraction of cardiac muscle is The?
The portion of the nervous system that is most closely associated with the contraction of the cardiac muscle is the autonomic nervous system.
3 kinds of muscles?
The three kinds of muscles are the smooth, cardiac and the skeletal. The smooth muscles are controlled by the autonomic nervous system. The cardiac muscles are in the heart and the skeletal help move our bodies.
What nervous system innervates cardiac and smooth muscles and glands?
They are controlled by the autonomous nervous system.== ==
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 is Skeletal muscles controlled by?
Skeletal muscles are controlled by motor neurons in the somatic branch of the peripheral nervous system, which is controlled by the central nervous system.
These muscles are controlled by the nervous system?
All muscles, all three types; skeletal muscle that moves your body, smooth muscle of the internal organs, and cardiac muscle of the heart.
Voluntary muscles are controlled by which nervous system?
Voluntary muscles are controlled by the central nervous system.
What is the classification of the muscular system?
The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture, and circulates blood throughout the body. The muscular system in vertebrates is controlled through the nervous system, although some muscles (such as the cardiac muscle) can be completely autonomous.There are three distinct types of muscles: skeletal muscles, cardiac or heart muscles, and smooth (non-striated) muscles. Muscles provide strength, balance, posture, movement and heat for the body to keep warm.CARDIAC MUSCLE:Heart muscles are distinct from skeletal muscles because the muscle fibers are laterally connected to each other. Furthermore, just as with smooth muscles, they are not controlling themselves. Heart muscles are controlled by the sinus node influenced by the autonomic nervous system.SMOOTH MUSCLE:Smooth muscles are controlled directly by the autonomic nervous system and are involuntary, meaning that they are incapable of being moved by conscious thought. Functions such as heart beat and lungs (which are capable of being willingly controlled, be it to a limited extent) are involuntary muscles but are not smooth muscles.
What kind of Eye muscles are controlled by the autonomic nervous system?
intrinsic eye muscles are controlled by the autonomic nervous system
Is every movement in your body controlled by your muscles?
No. they are controlled by your nervous system.
What muscles are controlled by the autonomic nervous system and operate the internal organs?
Smooth muscles
The involuntary muscles of the arteries are controlled by the system?
nervous system
What part of the body is controlled by the nervous system?
Every part of the body is controlled by the nervous system, either directly or indirectly.
