Under the microscope, the myofibrils appeared as distinct, striated bundles running the length of the muscle fiber.

Under the electron microscope, each myofibril showed distinct banding patterns that reflected its sarcomere organization.

My research focuses on myofibrillar adaptations in skeletal muscle following resistance training.

The researcher examined the myofibrillary structure under the electron microscope to understand muscle contraction.

Recent studies on muscle development have shed light on the molecular mechanisms driving myofibrillogenesis.

Recent studies have shed light on the mechanisms of myofibrilogenesis during muscle development.
