Question

Cardiac muscles are

• A. striated, voluntary with syncytial condition
• B. unstriated and involuntary
• C. striated, involuntary with intercalated discs
• D. involuntary and unstriated

Answer 1

The correct option is C striated, involuntary with intercalated discs

Cardiac muscles are found in the wall of heart. Cardiac muscle cells are striated as they have dark bands and light bands (striations). The working of these muscles is not under the conscious will of the organism, hence these are called involuntary muscles. The characteristic feature of these muscles is presence of intercalated discs which are communication junctions and allow the cells to contract as a unit.
