Unit 8: Physiology of Human Body Systems
Unit A: Understand the impact of disorders of the
musculoskeletal system and their associated and
corrective treatments.
Musculoskeletal disorders:
In this assignment I will be writing a report on the musculoskeletal systems, what is
good about them, some disadvantages and some examples of disorders. The
disorders I will be discussing are carpel tunnel syndrome, tendinitis and rheumatoid
arthritis.
The Musculoskeletal System:
All the bones in the body are involved in the skeletal system. This includes cartilage,
ligaments, tendons and connective tissue. The skeleton provides a framework for the
muscles and other soft tissues. The functions for the body are protection, movement
and support. The axial skeleton consists of bones, of the head and trunks of the
vertebrate. The bones of the appendicular skeleton make up the rest of the skeleton.
These are called appendicular as they are appendages of the axial skeleton. The
appendicular skeleton includes the bones of the shoulder girdle, the upper limbs, the
pelvic girdle, and the lower limbs.
Protection, movements and support:
The skeletal system supports the body by enabling movement with a support
structure and protects the vital organs of the body. The skeletal system offers a
scaffold and supports the weight of the whole body. Without a skeleton there would
be a mess of muscle and skin on the floor. Bones give the facility of movement by
acting as anchors of support and attachment points for muscle. Bones also protect
the vital organs by surrounding them with a hard cover. They protect the brain with
the cranium and ribs protect the lungs and heart.
,Mineral and fat storage, blood cell formation:
Bone tissue has many functions. Bones store important minerals such as
phosphorus and calcium. These minerals can be released into the body as needed.
Calcium is needed for muscle contraction and involved in nerve impulse
transmission.
Bones also store fat and make blood cell production. The connective tissues within
the bone are known as bone marrow.
There can be two type of bone marrow, one can be red and the other yellow. Yellow
contains adipose tissues and is a source of fat energy for the body, this can be
released as the body requires. The blood cells are produced in the red bone marrow.
These include white, red bloods cells and platelets.
The distribution of red and yellow bone marrow change with age.
The Bone:
When we are born a new baby has 270 soft bones. As the person ages, some of
these bones fuse and adults have 206 bones in total. The femur is the largest bone
in body and the smallest bone is the stapes which is in the middle ear and is about
3mm in length.
The bones are mainly made up of collagen, which is a type of protein. This acts as a
framework on which calcium phosphate mineral is placed, this then hardens to give
the bone strength. About 99% of the body’s calcium is stored in our bones and teeth.
The internal structure of bones is like a honeycomb. This makes the bones inflexible,
strong and very light weight.
