Gross and Microscopic Structure of Skeletal Muscle Including Ultrastructure of a Myofibril ...
Skeletal muscle is made of long fibers whose contraction provides the force of locomotion and other voluntary body movements.
skeletal muscle
Striated muscle generally responsible for the voluntary movements of the body.

skeletal muscle Muscle that is generally attached to the skeleton and causes body parts to move; consists of muscle ?bers. Voluntary muscle cells that have a striated appearance.
Skeletal Muscle Structure
Muscle fibers are multinucleated, with the nuclei located just under the plasma membrane. Most of the cell is occupied by striated, thread-like myofibrils. Within each myofibril there are dense Z lines.
Skeletal muscle or "voluntary muscle" is anchored by tendons to bone and is used to affect skeletal movement such as locomotion and in maintaining posture.
Skeletal Muscles / Striated Muscles
Skeletal muscles are usually attached to bones. They are often called striated muscles, because of their striated, or striped appearance.
Skeletal Muscle (striated) Unlike cardiac muscle, skeletal muscle can develop a sustained condition known as tetany through high frequency stimulation, resulting in overlapping twitches and a phenomenon known as wave summation.
Skeletal Muscle
Cardiac muscle resembles skeletal muscle in the regularity of the structural elements and the last of individual cells. However, it is not under voluntary control.
skeletal muscle Type of muscle tissue found in muscles attached to skeletal parts.
skin The outer integument or covering of an animal body, consisting of the dermis and the epidermis and resting on the subcutaneous tissues.

The individual muscle cells are joined through a junctional complex known as the intercalated disc and are not fused together into multinucleate structures as they are in skeletal muscle.
Preliminary studies have focused on cataloguing the features characteristic of skeletal muscle specific enhancers and promoters. Being able to determine the time and place of gene expression would be a useful step toward understanding its function.
An isoenzyme (an enzyme that appears in multiple forms) found in high concentrations in heart and skeletal muscles, and, in smaller amounts, in brain tissue. Each form of CK is predominant in specific tissues.
myogenesis - differentiation of skeletal muscle.
myxamoeba - in Dictyostelium discoideum, the solitary haploid cell of the vegetative life cycle that lives on bacteria and reproduces by binary fission until the food supply is exhausted.
