1.03 Understand the functions and disorders of
the skeletal system
Essential Standards:
Functions of the Skeletal System
What functions of the skeletal system are demonstrated in this picture?
1.03 Understand the functions and disorders of the
skeletal system 4
Functions of the Skeletal System
Discuss hemopoiesis- is the production of Red Blood Cells---RBC’s live about 120 days-
so production is constant- about
3 million created every second.
1.03 Understand the functions and disorders of the
skeletal system 5
Functions of the Skeletal System
Which minerals are stored in the skeletal system? Calcium and phosphorus
What is the relevance to your health? Makes bones strong

Arthritis
Define the term based on the meaning of its parts.arthr/o itis
Arthritis is inflammation of one or more joints. A joint is the area where two bones meet. There are over 100 different types of arthritis. Symptoms: Arthritis causes joint pain, swelling, stiffness, and
limited movement ...1.03 Understand the
functions and disorders of the skeletal system 12
Disorders of the Skeletal System
Arthritis Osteoarthritis
What is the cause? is the most common joint disorder, which is due to aging and Is due to aging and wear and tear on a Joint. If the cartilage breaks down and wears away, the bones rub
together. This away the bones rub together and causes pain, swelling, and stiffness.
Treatment: Medications, lifestyle changes, PT braces

Disorders of the Skeletal System
Arthritis Rheumatoid arthritis Discuss the characteristics of
rheumatoid arthritis. What is the relevance to health?
1.03 Understand the functions and disorders of the

Disorders of the Skeletal System
Arthritis Compare rheumatoid arthritis and
osteoarthritis. RA- chronic autoimmune Osteoarthritis-degenerative, aging What is the relevance to health? Both
affect motility, affects psychologicallly
1.03 Understand the functions and disorders of the
skeletal system 15
Disorders of the Skeletal System
Rheumatoid arthritis (RA) is a long-term disease that leads to inflammation of the joints and surrounding tissues. It can also affect other organs. Symptoms: RA usually affects joints on both sides of the body equally. It is an autoimmune disease, which means the body's immune system mistakenly attacks healthy tissue.

skeletal system 16
Gout Discuss gout.-metabolic disease ,
overproduction of uric acid-
deposits in joints
What causes gout? excessive
protein ingestion, possibly
inherited, 95% male , onset after
age of 30, 1.03 Understand the
functions and disorders of the skeletal system 18
Disorders of the Skeletal System
Gout Which joint is most often
effected? Big Toe
What other joints might be
affected? Ankles, hands
How is gout treated? Dietary
restrictions of protein, analgesics,
anti-inflammatory drugs.1.03 Understand the

Rickets
Discuss rickets.- a pediatric condition caused by lack of Vit. D leading to impaired Calcium absorption and calcification.
What causes rickets? Lack of Vit. D in diet.
Who is most often effected? Children.. 1.03 Understand the
functions and disorders of the skeletal system 23
Disorders of the Skeletal System
Normal legs
Rickets How is rickets treated?-
Dietary correction to increase Vit D.
How does rickets impact a person’s healthy function?
Is this a health concern in the U.S.? Why/why not?
