Involutary muscles are muscles that you can not control. Examples are smooth muscle (in the esophagus, iris, intestines, etc) and cardiac muscle.
almost any muscle spasms are caused many times by a lack of hydration. drink water, add electrolytes from like a gatorade, and take potassium supplements. if this doesn't help, try an ibuprofen or two and stretch the muscles as much as possible. biggest causes are vitamin, water, and electrolyte deficiencies.
Smooth muscle (unlike skeletal muscle) consists of individual cells (leiomyocytes), each cell with its own nucleus.
The function of smooth muscle also differs substantially from that of striated muscle.Each smooth muscle cell (or "muscle fiber") is just a few microns in diameter but may be two hundred microns long. The nucleus is also elongated, often cigar-shaped. The appearance, or visual texture, of smooth muscle varies dramatically depending on the orientation of the fibers with respect to the plane of section. Note especially the appearance of smooth muscle nuclei.an involintary muscle found in you're skin blood vessles and organs
