The average length of skeletal muscle cells in humans is about 3 cm (sartorius muscle up to 30 cm, stapedius muscle only about 1 mm). Their diameters vary from 10 to 100 µm. Skeletal muscle fibres contain many peripherally placed nuclei.

Nuclear movement and positioning is driven by cytoskeletal networks of microtubules (MTs), actin and/or intermediate filaments. In most cases these movements involve a connection between the cytoskeleton and the nuclear envelope. 3 Each cytoskeletal family exerts force on the nucleus in various ways.
Web11 de jun. de 2024 · In skeletal muscle fibers, the nuclei are distributed along the cell to maximize their internuclear distances. This myonuclear positioning is crucial for cell function. Although microtubules, microtubule associated proteins, and motors have been implicated, mechanisms responsible for myonuclear positioning remain unclear.
