I'm a newly appointed technical assistant by a large sports and fitness company and in this
assignment, I will explain the structure and the functions of the human musculoskeletal system that
supports mobility, leverage, organ protection, and blood cell formation, and mineral storage. In order
to succeed in this criteria, I need to use a scientific language and technical terminology to outline the
normal anatomy and physiology of the six major joints and must include bones, muscle groups,
tendons and ligaments that are involved in bringing about normal movement. In addition, I must also
explain the disorder that occurs in the skeletal system such as symptoms, treatments, and side
effects of the disorder.
Skeleton system
The skeletal system has a variety of functions such as allowing movement, producing blood cells and
providing protection of body organs and storing minerals. The musculoskeletal system consists of the
skeleton, muscles, joints, tendons, cartilage, ligament and other types of connective tissue which
allows for stability and movement. The bone tissue is composed of bone cells which are called
osteocytes and bone matrix which is made up of organic components such as collagen and inorganic
components such as calcium. This is because collagen gives bone flexibility while calcium provides
stiffness and without calcium, the bone would be soft and can easily be bent. Therefore, the skeleton
system plays an important role in our body by protecting the body's organs, maintaining the body's
weight, and giving the body form. The skeleton is made up of the body's bones, the adult skeleton has
206 bones while the infant has 300 bones. This is because certain bones fuse together between
childhood and adulthood to produce an adult bone. Therefore, the skeleton's primary function is to
generate a hard, internal structure capable of supporting the body's weight. As a result, the skeletal
system provides four vital purposes in our bodies such as mobility, protection, support, storage, and
the creation of blood cells and minerals.
● Movement - the skeletal system allows the body to move and the bones from the joints act as
a lever which allows them to pull in order to produce movement.
● Protection - the skeletal bones provide protection for internal organs such as the heart, brain
and other organs as it reduces risk and damage to the organs in the body. The rib cage, for
example, protects the lungs and heart, while the skull shields the brain from any harm. Finally,
the vertebrae support and protect the spinal cord.
● Support - The skeletal system holds the body upright and provides a shield or framework to
protect muscle and tissue attachments. The skeleton's bones act as a surface for muscle
attachment.
● Storage and production of mineral and blood cells - The red blood cell, white blood cells and
platelets are produced inside the bone which is called bone marrow and is made up of
minerals that act as storage for calcium and phosphorus.
The major function of the skeletal system is to provide a framework that can sustain the body’s
weight. As well as a structure which provides protection of the body's organs and also muscles may
be used to produce a physical movement such as biceps and triceps because triceps and biceps
enable arm extension. The lower part of the skeleton system is known as the appendicular system
which provides stability while running, walking and motion, whereas the upper part of the skeleton
system is called the axial system which has more mobility, ranges of motion, and lifting objects. As a
result, the skeletal system supports and protects the internal organs such as the lungs, heart, brain,
spinal cord, pelvic and other organs. Moreover, the skeleton bones are the major storage place for
essential minerals including calcium and phosphorus. In addition, the bone marrow also stores fat
and generates white and red blood cells and platelets to fight against any infection.
