Myofibrils are organized into groups called fascicles, which are bundles of muscle fibers. Each myofibril consists of repeating units called sarcomeres, the functional units of muscle contraction. These sarcomeres contain thick and thin filaments that slide past one another during contraction. The grouping of myofibrils and their organization within fascicles allows for efficient force generation and muscle movement.
What else can I help you with?
What is the smallest myfibril myofilament muscle fiber or fascicles?
The smallest unit among myofibrils, myofilaments, muscle fibers, and fascicles is the myofilament. Myofilaments are the microscopic protein filaments (actin and myosin) within myofibrils that are responsible for muscle contraction. Myofibrils are bundles of myofilaments, muscle fibers are composed of many myofibrils, and fascicles are groups of muscle fibers.

Can camphor and NaCl be saparated by sublimation?
Yes, because camphor is very volatile.
