What is the difference between involuntary muscle and cardiac muscle?

Answer 1

Voluntary (or skeletal) muscle cells, involuntary (or smooth) muscle cells, and cardiac (or heart) muscle cells, all have thick and thin filaments (myosin and actin, respectively), for their sliding filament mechanism, enabling movements However, since their funscions are different, there are significiant differences in their structures: shapes, sizes, proportion of filaments, their response to stimulus, and the kind of stimulus itself, for example.

Answer 2

The involuntary muscles of the body are smooth muscle and cardiac muscle. Skeletal muscle is the only voluntary muscle. So, there is no difference, but rather, cardiac muscle is a kind of involuntary muscle. Recall that involuntary muscles are innervated by the autonomic nervous system. Think of all the effects of the parasympathetic and sympathetic response on target organs. If the organ (e.g. the heart, digestive tract, etc.) is affected by the autonomic nervous system, it is composed of involuntary muscle. In summary, if the muscle can't be consciously controlled it is said to be involuntary.

Answer 3

its involuntary because it moves by its self we don't move it ~^.^~
