Question

Name the gross anatomy of the muscle from largest to smallest...

Answer 1

The order of the units within a skeletal muscle from smallest to largest is sarcomere, myofibril, muscle fiber, and fascicle.

Step-by-step explanation:

The proper order of the units within a skeletal muscle from smallest to largest is:

1. Sarcomere: The sarcomere is the basic contracting and functional unit of skeletal muscle. It is the smallest unit of organization in the muscle and is composed of actin and myosin filaments.
2. Myofibril: Myofibrils are made up of a linear arrangement of sarcomeres and are responsible for muscle contraction. They run parallel to each other within a muscle fiber.
3. Muscle fiber: Muscle fibers, also known as muscle cells, are long, cylindrical cells that make up the muscle. Multiple myofibrils run within each muscle fiber.
4. Fascicle: Fascicles are bundles of muscle fibers and are surrounded by connective tissue. They give muscles their distinct shape and allow for coordinated movement.
