Examples of myocyte in the following topics:
- Myocytes, sometimes called muscle fibers, form
the bulk of muscle tissue.
- The sarcolemma of myocytes contains numerous invaginations
(pits) called transverse tubules which are usually perpendicular to the length
of the myocyte.
- Each myocyte contains multiple nuclei due to their
derivation from multiple myoblasts, progenitor cells that give rise to
- These myoblasts asre located to the periphery of the myocyte and flattened so
as not to impact myocyte contraction.
- Each myocyte can contain many thousands of myofibrils.
- Muscle cells,
or myocytes, contain myofibrils comprised of actin and myosin myofilaments
which slide past each other producing tension that changes the shape of the
- Numerous myocytes make up muscle tissue and the controlled production
of tension in these cells can generate significant force.
skeletal myocytes are elongated and tubular and appear striated with multiple peripheral
- Cardiac myocytes
are shorter than skeletal equivalents and contain only one or two centrally
- Smooth muscle
myocytes are spindle shaped with a single centrally located nucleus.
- However, when multiplied by the number of sarcomeres in a myofibril, myofibrils in a myocyte and myocytes in a muscle, the amount of force and movement generated is significant.
