Biceps muscles, respiratory, alimentary and urogenital tracts are the places where voluntary muscles are found, while abdominal muscles, locomotory muscles, middle ear muscles, Diaphragm are the examples of the involuntary muscles.

Smooth muscle fibers are located in walls of hollow visceral organs, except the heart, appear spindle-shaped, and are also under involuntary control.

Muscles that are under your conscious control are called voluntary muscles. Muscles that are not under your conscious control are called involuntary muscles.

Involuntary Muscles:

Some examples of voluntary muscles include the biceps, the triceps, the quadriceps, diaphragm, pectoral muscles, abdominals, hamstrings, etc. Some examples of involuntary muscles include the cardiac muscle and smooth muscle lining the intestinal tracts, blood vessels, urogenital tracts, respiratory tract, etc.

You can control some muscle movements. However, certain muscle movements happen without you thinking about them. Muscles that are under your conscious control are called voluntary muscles. Muscles that are not under your conscious control are called involuntary muscles.
