Quick question....

Cardiac muscle which is also striated like Skeletal muscle, is it mononucleated? or more than one?

Destroyer tells me its mononucleated....

KBB and datqvault are telling me more than one nuclei

multi-nucleated. Skeletal muscle is formed by the fusion of myoblasts, each of which has its own nucleus. Therefore a skeletal muscle will have many nuclei.

Jab check this out, I used this as one of my flashcards:


Cardiac Single Nucleus Involuntary Striated
Smooth Single Nucleus Involuntary Non-Striated
Skeletal Multi Nucleus Voluntary Striated

So as you can tell cardiac and smooth are the same except when it comes to stridiations; thats when Cardiac and Skeletal are the same.

Cardiac muscles can be multinucleated, but mostly mononucleated. I recall from Physiology, my instructor said just to assume mono for cardiac and multi for skeletal.

For cardiac, the way you answer would depend on how the question is asked and what your choices are. If it asks which is multinucleated and you can only pick one, then you have to pick skeletal. If the question asks which is ALWAYS mononucleated then it'll be smooth, even if smooth and cardiac is one of the answer choices.

I guess it's possible to get a Q that asks which "is/are" multinucleated and the answer choices have every possible choice and combo. Then, it's kind of a coin toss, but I'd lean towards what's technically true instead of what's true most of the time.
