Solution
The correct option is D All four
All four statements are wrong.
Visceral muscles are the smooth muscles. They are unstriated, spindle-shaped and with a single nucleus. They perform all involuntary actions.
Intercalated discs are the characteristic feature of cardiac muscles.
Sarcosomes are the mitochondria of muscles fibres. Calcium stores are present in the smooth endoplasmic reticulum of the muscles fibres, called sarcoplasmic reticulum.
