What is meant by involuntary muscle?

Muscles that contract or move voluntarily are known as involuntary muscles. Involuntary muscle action is controlled by the autonomic nervous system. The internal organs or viscera that exhibit consistent, gradual contractions and involuntary motions are typically connected with these muscles. The heart is one such uncontrollable muscle.The autonomic nervous system, hormones, and local variables can cause the involuntary activity of the majority of involuntary muscles by neural stimulation. But in other muscles, such as the walls of visceral organs, extending the muscle can cause an involuntary muscle contraction.

Therefore, option (C) is correct.

A. Insulator, semiconductor, conductor
B. Conductor, semiconductor, insulator
c. Semiconductor, insulator, conductor
O D. Semiconductor, conductor, insulator

Answers

The correct option that lists materials in order by their ability to allow the flow of electrons, from least easily to most easily, is Insulator, Semiconductor, and Conductor, which is in Option A.

What are an electron, an insulator, etc.?

The ability of a material to conduct electricity depends on the number of free electrons that are available to move through the material. In an insulator, there are very few free electrons, which means that the material does not conduct electricity very well. Insulators are typically used to prevent the flow of electricity, for example, in electrical wiring, where plastic or rubber coatings are used to insulate the copper wires.

Hence, the correct option that lists materials in order by their ability to allow the flow of electrons, from least easily to most easily, is Insulator, Semiconductor, and Conductor, which is in Option A.
