Unit 8 Learning Aim A - Musculoskeletal System
P1 – Explain the functional role of the musculoskeletal system in the human body.
P2 – Describe the effect of disorder of muscles and joints and possible corrective treatment(s).
M1 – Compare how disorders of the musculoskeletal system can affect how muscles bring about
movement of joints and the importance of corrective treatment.
D1 – Evaluate the effect of corrective treatment(s) associated with a musculoskeletal disorder.
P1
I have been “employed by a large sports and fitness company as a trainee Health Care Assistant
within an Occupational Health Department (OHD). My employers are concerned that a significant
number of working days are lost due to employee absence through musculoskeletal disorders. They
hope that by liaising with other Health Care professionals, the OHD will be able to create support
programmes that offer employees education and guidance regarding the structure and function of
the musculoskeletal system, the clinical management of common musculoskeletal disorders. The
company’s management team hope that this initiative will reduce absences by expediting employees
return to work in the shortest possible time.” As a result of this, my role is to carry out research in
order to produce information that will be used to educate the employees. Within my report, I will
firstly be explaining the functional role of the musculoskeletal system in the human body (P1). Then,
I will be describing the effect of disorder of muscles and joints and possible corrective treatment(s)
(P2). Furthermore, I will compare how disorders of the musculoskeletal system can affect how
muscles bring about movement of joints and the importance of corrective treatment (M1). To
conclude the report, I will evaluate the effect of corrective treatment(s) associated with a
musculoskeletal disorder (D1).
The musculoskeletal system is a system that
contains two organ systems: the muscular
and skeletal systems. They work
simultaneously to support and provide
movement for the body, stability, and shape.
The musculoskeletal system is therefore a
crucial unit of physiology. All types of
muscles in the body are used in the muscular
system. In fact, skeletal muscles are the ones
that operate on the joints of the body to
generate movements. The muscular system,
in addition to the muscles, involves the
tendons that connect the muscles to the
bones. The principal part of the skeletal system is the bone. Bones connect with each other and form
the joints, giving a hard-core, but flexible, skeleton to our bodies. The stability and function of the
bones and joints are supported by the skeletal system's accessory structures; articular cartilage,
bursae, and ligaments.
The musculoskeletal system has numerous other roles in addition to its primary purpose to provide
the body with stabilisation and mobility; the skeletal component plays an important role in other
homeostatic functions such as mineral storage (e.g., calcium) and haematopoiesis, while the

muscular system retains most carbohydrates in the form of glycogen in the body. It also provides
protection for the vital organs within the body.
The musculoskeletal system is important for the structure and stability of the body and for securing
the organs within it. The skeletal system is important for storing calcium, phosphorus, and critical
components of the haematopoietic system. The musculoskeletal system is made up of bones,
muscles, joints, tendons, ligaments, as well as the axial and appendicular skeletons. These parts all
work together to provide support, protection, and movement in the body. There are two main
systems involved within the musculoskeletal system, these are: the muscular and skeletal system.
They both play a part in the structure, stability, and movement of the body.
Bones provide our bodies with support and help to construct our shape. Though exceptionally light,
the bones in our bodies are large enough to carry all our weight. Bones even shield the organs of the
body. The skull shields the brain and produces the outline of the face. Body support, facilitation of
motion, security of internal organs, preservation of minerals and fat, and haematopoiesis are the
main purposes of the bones. Tough connective tissues called tendons bind skeletal muscles to the
skeleton. The ends of bones that intersect at a joint are connected to several skeletal muscles. The
muscles span and link the bones around the joint. They tug on the bones as the muscles contract,
forcing them to move. By contracting and then releasing, muscles move body parts, they can pull
bones, but they cannot force them back to the original location, so they work in pairs of flexors and
extensors. To bend an arm at a joint, the flexor contracts.
Ligaments are short bands of strong, elastic tissue composed of many individual fibres linking the
bones of the body together. It is likely to find ligaments linking most bones in the body. A ligament's
purpose is to provide a passive restriction to the amount of motion between the bones. There are
approx. 900 ligaments in the human body. Structures are secured and prevented from bending,
twisting, or breaking by the tight connective tissue in the ligaments. Ligaments tend to preserve
stability in the body, regardless of whether they attach bones or organs to each other, which is why
they are one of the essential aspects of the skeletal system.
A tendon is a connective fibrous tissue that connects bone to muscle. Tendons can bind muscles to
components like the eyeball as well. A tendon serves
to move the bone or structure. The primary function
of the tendons is to transfer forces from the muscle
to the bone and absorb external forces to avoid
muscle damage. This function can become overly
complicated when the tendon operates from a very
cooperative tissue (the muscle) to a ridged stiff one
(the bone), which can lead to strain localised at the
site of merging tissues. This can be a prevalent place for injuries. Tendons are important as they
connect our muscles to our bones, thus allowing us to be able to move.
The bone is live, developing tissue, mainly composed of collagen. Collagen is a protein that creates a
soft foundation and a mineral that gives strength and hardens the structure is calcium phosphate.
This collagen and calcium mix makes the bone sturdy and resilient enough to survive tension. The
bone also contains blood vessels and nerves that nourish it. To sustain healthy bones and to perform
certain significant tasks, the body requires calcium. In bones and teeth, nearly all calcium is stored
where it maintains their structure and hardness. For muscles to move and for nerves to pass signals
from the brain and any body part, the body also needs calcium. Bone remodelling includes the
removal through osteoclasts of mineralized bone accompanied by the development of bone matrix
