Question

Is the organization and numbers of myofilaments the same as or different than skeletal muscle?

1) Same
2) Different

Answer 1

The organization and numbers of myofilaments are different in skeletal muscle compared to other muscle types.

Step-by-step explanation:

The organization and numbers of myofilaments are different in skeletal muscle compared to other muscle types.

In skeletal muscle, each fiber consists of bundles of myofibrils, which are composed of protein filaments called actin and myosin. These filaments are arranged in repeating units called sarcomeres, which give skeletal muscle its striated appearance.

In contrast, smooth muscle lacks striations and sarcomeres but does contain actin and myosin filaments. Cardiac muscle, although also striated, has a different arrangement of filaments than skeletal muscle.
