As the name suggests, Cardiac muscles are the muscles of heart. Many cardiac muscle cells assemble in a branching pattern to form a cardiac muscle. Based on appearance, cardiac muscles are striated. They are involuntary in nature as the nervous system does not control their activities directly.
Assertion (A): Cardiac muscles have unique characteristics among muscle types. Reason (R): Cardiac muscles are striated and voluntary like skeletal muscles.
Correct answer: C — If assertion is true but reason is false.
NCERT confirms cardiac muscles have unique characteristics (Assertion true). However, NCERT states “Based on appearance, cardiac muscles are striated. They are involuntary in nature as the nervous system does not control their activities directly” - cardiac muscles are striated but involuntary, not voluntary like the Reason claims.
