... muscle. The perimysium is a connective tissue layer that surrounds each
fascicle. ... The dark bands within a muscle fiber are called A bands, while the ...
Slow fibers are also called red fibers because they contain the red pigment
Skeletal muscles are composed of striated subunits called sarcomeres, which are
... Each myofibril is composed of numerous sarcomeres, the functional ...
The multiple nuclei arise from the fact that each muscle fiber develops from the
fusion of many cells (called myoblasts). ... Anything that lowers the level of
myostatin also leads to an increase in fiber size.
