Unlike involuntary muscles voluntary muscles are attached to bones. For example the human eyes exhibit several types of involuntary movement such as the constriction of the pupil in bright light or the expansion of it in dim light. What are voluntary muscles. Involuntary muscles are visceral.

The voluntary muscle contains multinucleated cells while the involuntary muscle has no initiation. Voluntary muscle is under the control of the autonomic nervous system while the involuntary muscle is under the control of the somatosensory nervous system. Voluntary muscles or striated muscles are those which work according to the one s desire or are under control whereas involuntary muscles are not under one s control. Diaphragm pharynx abdominal wall tongue muscles of middle ear muscles underneath the skin are few examples of voluntary muscles blood vessels alimentary tracts ducts of glands urogenital tracts respiratory tracts are few examples of involuntary muscles.

The muscle cells in the voluntary muscles are long cylindrical and unbranched with the nucleus located towards the periphery of the cell. The main difference between voluntary and involuntary muscles is that voluntary muscles are innervated by the somatic nervous system whereas involuntary muscles are innervated by the autonomic nervous system.
