Under a light microscope, how does a cross-section of smooth muscle appear compared to a longitudinal section?
Show answer and explanation
Correct answer: It shows profiles of varying size, some without nuclei
Because smooth muscle cells are spindle-shaped and staggered, a cross-section will cut through the wide centers of some cells (showing a nucleus) and the narrow ends of others (appearing as small, non-nucleated circles of varying diameter).
