Kaye
the heart is made of smooth muscle as are the linings of arteries,the uterus and the bladder
the muscles that work on the skeletal system, your breathing muscles, facial expression muscles, eye muscles, etc are striated muscles and work differently, are affected differently by medications and other compounds.
That is why they can paralyze a patient's (striated) muscles during surgery or when a patient is on a ventilator, yet the patient's heart keeps beating
Hope this helps!
