A biopsy from the wall of the urinary bladder reveals non-striated, spindle-shaped cells with a single nucleus. The tissue is identified as:

A. Skeletal muscle
B. Cardiac muscle
C. Smooth muscle
✓
D. Tendon

📝 Explanation

Correct: Smooth muscle consists of spindle-shaped, non-striated, uninucleate cells found in hollow organs. A: Skeletal muscle is striated and multinucleated. B: Cardiac muscle is branched and found only in the heart. D: Tendons are connective tissue. Concept: Identification of smooth muscle.
