What tissue separates the short, thin muscle fiber bundles known as myotomes in fish flesh?
Answer
Myosepta
The fundamental difference in texture between fish and terrestrial meats stems from the organization of the muscle structure. Fish flesh is segmented into short, thin bundles of muscle fibers called myotomes. These segments are separated from each other by thin layers of connective tissue known specifically as myosepta. Because this connective tissue is relatively weak and dissolves easily, particularly when exposed to gentle heat, the muscle fibers separate effortlessly, leading to the characteristic flakiness associated with cooked fish. This contrasts sharply with land animals where muscle fibers are longer and bound more tightly by stronger connective tissue.
