Question

What are involuntary muscles? Provide Examples?

Answer 1

Hint: Muscle is a type of contractile tissue that is organized into systems for greater efficiency. Muscle systems in humans are classified based on their gross appearance and cell location. striated (or skeletal), cardiac, and smooth muscles are the three types of muscles (or non striated).

Complete answer:
Myogenesis is the process by which muscle tissue is produced from the embryonic mesodermal germ layer. There are three types of muscle: striated muscle, cardiac muscle, and smooth muscle. Muscle action is divided into two categories: voluntary and involuntary. Cardiac and smooth muscle contractions are involuntary, whereas skeletal muscle contractions are voluntary.
Unstriped or non-striated muscles are other names for involuntary muscles. The muscles that function or contract without conscious control and are controlled by the autonomic nervous system are known as these muscles. Uninucleate, small, spindle-shaped involuntary muscles are found in the abdominal muscles, cardiac muscles, locomotory muscles, middle ear muscles, and the diaphragm.
The involuntary muscles' role is to cause changes in the shape or inner diameter of the organs (movement of substances inside the body, favoring possible passageways or the exclusion of contents). The autonomic nervous system controls their contraction. The heart is an example of an involuntary muscle.
The contraction of involuntary muscles is slower and more rhythmic than that of voluntary muscles. Involuntary Muscles include Cardiac Muscles, Smooth Muscles, and Skeletal Muscles.
Thus, Unstriped or non-striated muscles are another names for involuntary muscles. These muscles are those that function or contract without conscious control and are controlled by the autonomic nervous system. . Involuntary Muscles include Cardiac Muscles, Smooth Muscles, and Skeletal Muscles.

Note: When viewed under a microscope, the cardiac muscle has striations, but its contractions are not controlled by the will. The autonomic nervous system is a part of the peripheral nervous system that is responsible for the involuntary action of smooth and cardiac muscles. These involuntary muscles are stimulated by the autonomic nervous system.
