The medulla oblongata.
When a person is startled there is often an involuntary reaction of a twitch or small jerking movement. Eyes also blink involuntarily when something suddenly approaches them. Many other actions such as gasping, laughing, or yawning, can happen involuntarily.
No!!! Your body has both voluntary and involuntary muscles. The voluntary ones are the ones that you can freely move yourself. Bending your arm, pick up heavy objects ect. The involuntary muscles are the ones you have no control over. For example the beating of your heart, inhaling and exhailing or vomitting are among some of the involuntary muscles.
The somatic nervous system controls the voluntary movement of skeletal muscles, such as when you move your arm. The autonomic nervous systems controls the involuntary actions of internal organs and glands. The beating of your heart is controlled by this system. The autonomic nervous system is further broken up into two parts: the sympathetic, which controls arousal (think fight-or-flight), and the parasympathetic, which controls calming (think rest and digest).
The autonomic nervous system, dividing into sympathetic and parasympathetic nervous systems, controls the involuntary life-sustaining functions of the body. It controls heart rate (keeping the heart beating properly), blood pressure (through vasoconstriction and vasodilation), adrenaline release for glycogen breakdown to glucose to aid fight-or-flight responses, digestive system parastalsis, and even glandular release for digestion, immune response, etc., interacting with other hormone systems. The central nervous system interacts with the skeletomuscular system via motor control, as well as reflex feedback. It receives sensory input, processes it, and responds. Since a critical part of the brain is the hypothalamus, and the hypothalamus interacts with and controls the pituitary gland (the master gland of the endocrine system that controls all of the body's hormone systems), the brain also controls the endocrine system.
Involuntary muscles perform the work of internal organs. In the case of the digestive tract, peristaltic muscles are smooth muscle that surrounds the intestines; the heart uses cardiac muscle, a special kind of striated muscle.
Two kinds of body movement are voluntary and involuntary. Voluntary movements are consciously controlled, such as raising an arm to wave. Involuntary movements occur without conscious control, like the beating of the heart.
The whole structure is called the brain stem. The brain stem is divided up into three sections: midbrain, pons, and medulla oblongata. Regulation of vital functions occurs in your medulla oblongata. The medulla oblongata is sometimes referred to as the vital center.

Nope- that is why they are involuntary. You cannot will your heart to beat- or stop beating.
involuntary muscles
It's involuntary, but some do have a limited degree of control.
Yes, its like the heart beat it's always beating because of the involuntary muscles When you sleep the involuntary muscles make you breath
yes, an heart beating is an invoulantary muscle because you don't have to think about making it beat.
powerful, beating, drumming, strong controls

Involuntary muscle movement includes peristalsis in the GI tract and the beating of your heart. Generally involuntary muscles are smooth muscles (intestines, blood vessels), but the cardiac muscles are sometimes categorized as striated due to their structural similarities to skeletal muscles.
Involuntary, because we don't think about our hearts beating.
