Skeletal muscle fiber is a muscular tissue that is attached to the skeletal system. the skeletal muscle fibers are striated muscles i.e have striations in their structure. The skeletal muscle fibers are voluntary muscles i.e they can be controlled.
Motor unit is a composed of a motor nerve cell attached to a muscle fiber with its axon terminals. Motor nerve cells or neurons are the types of neurons that send impulses from the central nervous system to the responding organ. The muscle fiber may be attached to many neurons not only one neuron. Collectively, all the neurons attached to the same muscle fiber are called motor pool.
A skeletal muscle twitch is the contraction of a muscle fiber in response to the minimum stimulation.
The electrical stimulus is the stimulation of a skeletal muscle fiber by using external electrical impulses. The electrical stimulus is important in many sporting and medical situations.
A latent period is a period between applying a stimulus to a muscle fiber and the response of this muscle fiber by contraction.

Well I know that many diseases break down in the cell communication and cell cycle is how cells move or their stages
Because the area on Earth that's inside the tip of the moon's shadow is
usually only a couple of hundred miles wide at most, and it's moving along
the Earth's surface at thousands of miles an hour, and only the people who
happen to be inside that little area see the total solar eclipse.
Over a substantial period of time, the numbers of solar and lunar eclipses
are equal. For example, during the 100 years of the 20th Century, there
were 128 solar eclipses, and 129 lunar ones.
The difference is that during a lunar eclipse, everybody on the night side of
Earth can see it, but during a solar one, you have to be in just the right place
on the day side.
Another way to look at it:
A lunar eclipse happens on the Moon, and anybody who can see the Moon
can see the eclipse. But a solar eclipse happens on the Earth, and in order
to see it, you have to be where the eclipse is.
