Most of study guides shows that cardiac muscle has one or two nucleaus. If question asks, cardiac muscle is multi-nucleated then would you say true or false?

Yes, cardiac muscle is multi-nucleated, on the other hand, smooth muscle is just that "smooth" because it's nucleus is the head cheese!

so on a question went it asked which one is/are multicleated? would it be both skeletal and cardiac because this question came up several times for me and i usually answer cardiac as monocleated because it often referred as that in the question and i've been getting these questions rite. i've looked it up and cardiac muscle are normally monocleated in human. there are exception to other species but i think that we're supposed to treated as normally monocleated unless specifies exactly which type of species. rite??

Original question goes similar to this.

Cardiac muscle is
a. is innervated by the somatic motor neuron system
b. is not straited
c. is multi-nucleated
d. has voluntary contaction
e. doesn't require Ca

To me none of them are answer unless there is typo on the question.

Cardiac muscle can be mono or multi nucleated, so the BEST answer for this question is C.

Ditto.

Um... ok however, the answer indicated that it's D. So I thought they miss typed "involuntary" to "voluntary".

Is this question from the Kaplan book's practice test? I remember it, and I had the same problem. I think it's a typo...all of them are wrong.

No. Cardiac muscle can have more than one nucleus, so answer C is not wrong.
