What is the difference between voluntary muscle and involuntary muscle?

Voluntary muscle is muscle tissue that is under the conscious control of the central nervous system. This type of muscle is used for body movement, such as walking, running, and talking. Voluntary muscles are also known as skeletal muscles because they are attached to the bones of the skeleton.

Involuntary muscle is muscle tissue that is not under the conscious control of the central nervous system. This type of muscle is found in the walls of internal organs, such as the stomach, intestines, and heart. Involuntary muscles are also known as smooth muscles because they have a smooth appearance under a microscope.

The main difference between voluntary and involuntary muscle is the type of control that the central nervous system has over them. Voluntary muscles can be consciously controlled, while involuntary muscles cannot. This difference is due to the different types of nerve cells that innervate the two types of muscle tissue. Voluntary muscles are innervated by somatic nerve cells, while involuntary muscles are innervated by autonomic nerve cells.

Here is a table summarizing the key differences between voluntary and involuntary muscle:

| Feature | Voluntary Muscle | Involuntary Muscle |

|---|---|---|

| Control | Conscious | Unconscious |

| Location | Attached to bones | Walls of internal organs |

| Appearance | Striated | Smooth |

| Innervation | Somatic nerve cells | Autonomic nerve cells |

Functions of voluntary and involuntary muscle

Voluntary muscles are used for a variety of body movements, including:

* Walking

* Running

* Jumping

* Throwing

* Lifting

* Speaking

* Writing

Involuntary muscles are used for a variety of functions, including:

* Digestion

* Respiration

* Circulation

* Excretion

* Reproduction

Disorders of voluntary and involuntary muscle

There are a number of disorders that can affect voluntary and involuntary muscles. Some of these disorders include:

* Muscular dystrophy

* Myasthenia gravis

* Parkinson's disease

* Multiple sclerosis

* Stroke

These disorders can cause a variety of symptoms, including muscle weakness, fatigue, pain, and stiffness. Treatment for these disorders depends on the specific condition and may include physical therapy, medication, and surgery.
