Assertion : Smooth muscles are known as involuntary muscles Reason : Smooth muscles are controlled by autonomic nervous system
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect

Cardiac muscle cells differ from striated muscle cells in having
1 Myofibrils
2 No sarcoplasmic reticulum
3 A centrally located nucleus
4 Fewer mitochondria
Explanation:
The cardiac muscle fibres are uninucleate and their nuclei are centrally placed. Striated muscle fibres are multinucleate and their nuclei lie at irregular intervals.

Muscles of intestine and blood vessels are
1 Voluntary and smooth
2 Involuntary and smooth
3 Voluntary and striated
4 Involuntary and striated
Explanation:
The wall of internal organs such as the blood vessels, stomach and intestine contains smooth muscle tissue. Smooth muscles are 'involuntary' as their functioning cannot be directly controlled

Skeletal muscle are found in
1 Heart
2 Stomach
3 Biceps
4 Intestine
Explanation:
Skeletal muscle tissue is closely attached to skeletal bones. In a typical muscle such as the biceps, striated (striped) skeletal muscle fibres are bundled together in a parallel fashion.
