Muscle is composed of many long cylindrical-shaped fibres from 0.02 to 0.08 mm in diameter.
Each of the connective tissue sheaths found throughout skeletal muscle is composed of collagen, a structural protein that provides strength and support to the muscles.
Skeletal muscle is composed of fibrils whose organization defines functionality.
The iliopsoas muscle is composed of the psoas and iliacus muscle [1].
Skeletal muscle is composed of post-mitotic, multinucleated fibres.
Skeletal muscle is composed of two basic fiber types.
As the EDL muscle is composed almost entirely of fast-twitch (type II) fibres [24], one would expect that shifts towards slower-twitch properties would be more apparent in this muscle.
In all vertebrate organisms, including humans, skeletal muscle is composed of a variety of muscle fiber types, each with specialized roles that support the body's skeleton and enable the organism to perform a wide range of movements [1].
While studying the effects of estrogen and ERs in culture warrants merit and has yielded important information, intact skeletal muscle is composed of fused myotubes, is multi-nucleated, and innervated.
Similarly, mammalian skeletal muscle is composed of syncytial myotubes.
