A. Skeletal and Cardiac — voluntary
B. All three voluntary
C. Only Smooth — voluntary
D. Skeletal — voluntary; Cardiac and Smooth — involuntary ✓ Correct
Solution: Only skeletal muscle is voluntary; both cardiac and smooth muscle are involuntary.
Q7 — Muscular Tissue · easy · numerical

A. Smooth (unstriated) muscle ✓ Correct
B. Cardiac muscle
C. Skeletal (striated) muscle
D. Voluntary striated muscle
Solution: Smooth muscle has tapering unstriated fibres and works involuntarily; it forms the walls of the alimentary canal, blood vessels and other internal organs.
Q8 — Muscular Tissue · easy · numerical
Skeletal muscle fibres are described as striated and voluntary because they:
A. Lack any bands and are found only in the heart wall
B. Are branched, uninucleate and beat rhythmically on their own
C. Are spindle-shaped and contract without conscious control
D. Show alternating light and dark bands and contract under conscious control ✓ Correct
Solution: Skeletal muscle shows cross-striations from regularly arranged actin/myosin and is under voluntary (conscious) control, being attached mainly to bones.
Q9 — Muscular Tissue · easy · numerical
Which combination correctly identifies cardiac muscle?
A. Striated, involuntary, branched fibres joined by intercalated discs ✓ Correct
B. Unstriated, involuntary, branched fibres without discs
C. Striated, voluntary, long unbranched fibres
D. Unstriated, voluntary, spindle-shaped fibres
Solution: Cardiac muscle is striated but involuntary, with branched fibres linked at intercalated discs that allow synchronised contraction of the heart.
Q10 — Muscular Tissue · medium · numerical
Assertion (A): Cardiac muscle can contract in a rhythmic, coordinated wave even though it is not under our will. Reason (R): The branched cardiac fibres are joined end to end by intercalated discs that permit rapid spread of excitation. Choose the correct option.
A. A is false but R is true
B. Both A and R are true and R is the correct explanation of A ✓ Correct
C. A is true but R is false
D. Both A and R are true but R is not the correct explanation of A
Solution: Intercalated discs electrically couple adjacent cardiac fibres so an impulse spreads quickly, giving the heart its rhythmic, coordinated involuntary beat; R explains A.
Q11 — Muscular Tissue · medium · numerical

B. (i)-p, (ii)-q, (iii)-r
C. (i)-q, (ii)-r, (iii)-p
D. (i)-r, (ii)-p, (iii)-q
Solution: Skeletal fibres are long, cylindrical, unbranched and striated; smooth fibres are spindle-shaped and unstriated; cardiac fibres are branched with intercalated discs.
Q12 — Muscular Tissue · medium · numerical
Which of the following statements about muscular tissue is INCORRECT?
A. Skeletal muscle is mostly attached to bones through tendons
B. Muscle cells are elongated and contain contractile proteins actin and myosin
C. Cardiac muscle fatigues far less readily than skeletal muscle
D. Smooth muscle fibres possess prominent cross-striations like skeletal muscle ✓ Correct
Solution: Smooth muscle is unstriated (no cross-striations); the other statements are correct, making the striation claim the incorrect one.

C. Skeletal muscle in the heart wall, cardiac muscle in the gut, smooth muscle in the limbs
D. Smooth muscle attached to bones, skeletal muscle in the iris, cardiac muscle in the intestine

Solution: Skeletal muscles are striated and voluntary (not involuntary), so only 'striated in appearance' is correct.
Q22 — Muscular Tissue · hard
Which of the following statements wrongly represents the nature of smooth muscle? (1) These muscles are present in the wall of blood vessels. (2) These muscles have no striations. (3) They are involuntary muscles. (4) Communication among the cells is performed by intercalated discs.

D. (ii), (iii), (iv) and (v)
Solution: True: (i), (ii), (v). False: (iii) and (iv) refer to cardiac muscle - intercalated discs are communication junctions of cardiac (not skeletal) muscle that let cells contract as a unit.
Q26 — Muscular Tissue · medium
Assertion: Cardiac muscle cells contract as a unit. Reason: Cell junctions or intercalated discs fuse the plasma membranes of cardiac muscle cells and make them stick together.
A. Assertion and reason both are true but reason is not correct explanation of assertion.
B. Assertion and reason both are wrong.
C. Assertion is true but reason is wrong.
D. Assertion and reason both are true and the reason is correct explanation of assertion. ✓ Correct
Solution: Both are true: intercalated discs/communication junctions fuse adjacent cardiac cells so the impulse spreads and they contract as a single functional unit, so R correctly explains A.
Q27 — Muscular Tissue · medium
Assertion: Both skeletal muscles and cardiac muscles have a striated appearance. Reason: Cardiac muscles are involuntary in nature.
A. Both assertion and reason are true, and reason is the correct explanation of assertion.
B. Both assertion and reason are true, but reason is not the correct explanation of assertion. ✓ Correct
C. Both assertion and reason are false.
D. Assertion is true, reason is false.
Solution: Both skeletal and cardiac muscle are striated (A true) and cardiac muscle is involuntary (R true), but being involuntary has nothing to do with striation, so R does not explain A.
Q28 — Muscular Tissue · hard
The type of muscle present in our
A. Heart is involuntary and unstriated smooth muscle. ✓ Correct
B. Thigh is striated and involuntary.
C. Intestine is striated and involuntary.
D. Upper arm is smooth muscle and fusiform in shape.
Solution: Only the heart statement correctly identifies it as involuntary; cardiac muscle is involuntary (option 1 is the intended key). Intestinal muscle is smooth, and thigh/upper-arm muscles are striated and voluntary.
