Muscle growth is due to increases in protein content within muscle cells.

◐Partially SupportedMuscles can undergo healthy increases in cell size (hypertrophy), unlike epithelial cells.

✕Not SupportedThe contribution of increased muscle fiber size to strength gains after approximately 3-4 weeks is a view that has recently been challenged.

◐Partially SupportedHyperplasia does not play a significant role in muscle growth in adults.
