Question

Involuntary muscle fibres are found in

• A. Diaphragm; eye muscles; intercostal muscle
• B. Urinary bladder; blood vessels
• C. Both A and B
• D. None of the above

Answer 1

The correct option is C Both A and B

Involuntary muscles are those, which are not under our control. Diaphragm muscles are internal muscle, that divides the thorax and the abdomen and are involuntary. The walls of large organs like stomach, intestines, uterus and urinary bladder are involuntary.
Thus, the correct answer is option (C), 'Both (A) and (B)'.
