Functioning of Muscular System in Movement of Knee Joints
Role of muscular system in movement
Muscular system refers to an organ system that consists of smooth, skeletal and cardiac
muscles. It allows movement of the body, circulates blood and maintains posture throughout the
body. In addition, the muscular system refers to the set of tissues within body with the capability
to change shape. It is composed of the specialised cells that are called muscle fibres. Muscles,
attached to internal organs or bones and blood vessels, are dependable for movement. Practically,
all movement inside the body is the output of muscle contraction. The integrated action of bones,
joints, and skeletal muscles makes obvious movements such as running and walking. Therefore
muscular system in the body plays an important role for an individual who are interested in
sports and daily basis exercise (Asano and et. al., 2016).
There are different characteristics of Muscular system which helps human to movement
their body easily. These characteristics are muscles are attaches to bones by tendons, three types
of muscles are cardiac, smooth and skeletal, four functions of muscle contraction are posture,
joint stability, movement and heat production, muscle features such as shape, size, direction of
fibbers, number of origin, origin and insertion location and action are frequently used in naming
muscles etc. These are effective characteristics of Muscular system which will be beneficial for
those who have interested in sports and exercise. Along with this, one of the most main
characteristics of muscular system is its contractility as well as nearly all movement inside the
body is the better output of muscle contraction. Every muscle fiber is delimited by endomysium.
The fibbers are gathered into bunches covered by perimysium. A lot of bunches, or fasciculi, are
wrapped jointly by the epimysium to shape a whole muscle (Asano, Okada and Inaba, 2017).
One of the main roles of Muscular system is to permit movement. The Muscular system
can be divided into three forms of muscles which are cardiac, skeletal and smooth. The muscles
inside the body help to maintain posture, support movement and circulates flow of blood and
many other substances throughout the body. There are different roles or functions of Muscular
system in human body, especially spotters. These ate mobility, stability posture, circulation,
respiration, digestion, urination, childbirth, vision, organ protection and temperature regulation.
All these are main roles that were played by Muscular system in body. These roles will support a
person in walking, running, excising and many other activities. The muscular system’s main role
