Describe the organization of the locomotor white muscles of fish as well as the direction of the contractile forces

What will be an ideal response?


Answer: The white muscle fibers are organized into embryologically derived myotomes separated by thin layers of connective tissue called myopsepta. Tendons connect each myotome to the posterior; the skin acts as a sheath to connect the different myotomes. During contraction, force is transmitted from one myotome to the next across myosepta to the caudal fin along the tendons and to the skin.
