Statement : It provides quick, powerful, and rhythmic contractions to the heart.
Read the following statements:
(i) Smooth muscles may show striations.
(ii) Striated muscles are branched, syncytial and fusiform.
(iii) Smooth muscle fibers are uninucleated and taper at both ends.
(iv) Cardiac muscles have gap junction and intercalated discs.
Which of the above statements are correct?
Distinguish between:
(b) Cardiac muscle and striated muscle.
Identify true (T) and (F) among the following statements and choose the correct option:
(i) Smooth muscle fibers are uninucleate and involuntary.
(ii) Due to presence of very few gap junctions, the cardiac muscles contract together as a unit.
