Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.

Question

What do you mean by innervation of smooth muscles?

Expert Solution

Smooth muscles

Smooth muscles are present all over the body. They are involuntary in functions and are non-striated in appearance. Smooth muscles are present in a variety of organs like the stomach, intestines, blood vessels, etc. In the stomach and intestines, smooth muscles help in digestion, whereas in the blood vessels, they help in increasing and decreasing the diameter of the blood vessels.
