involuntary
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.
we can identify the types of muscle based on structure and function. like voluntary and involuntary, and also striped or nonstriped
the heart is an involuntary muscle thats keeps the whole body alive and functioning
Voluntary muscle movements are the result of conscious effort by the brain. Involuntary muscles such as the heart or smooth muscles in the gut and vascular system contract as a result of non-conscious brain activity or stimuli proceeding in the body to the muscle itself.Your answer: The heart and smooth muscles in the gut and vascular system (lungs) are muscles that work "without thinking about it" -- we call these "involuntary" muscles.
Skeletal muscle
well it depend what you mean i can kind of controll it voluntary or involintary i do it involuntary when riding but starting i do it voluntary for most people ints voluntary
The heart is made up of 3 layers of cardiac muscle (different to voluntary and smooth muscle). Epicardium, myocardium and endocardium.
involuntary muscle
Voluntary Smooth Muscle
You can control voluntary muscles.
The heart essentially is a muscle. Myocardium or cardiac muscle forms the majority of the heart and its chambers. It is It is an involuntary muscle, that is opperates on an automatic/unconcious level. It differs by several characteristics from smooth muscle (found in places such as the intestinal tract, stomach etc) and skeletial muscle (the muscle's you can EASILY see on body builders).
