The Skeletal System APPLIED ANATOMY AND PHYSIOLOGY Flashcards
Name the 14 bones we need to know.
Cranium Vertebrae Scapula Humerus Ribs Sternum Radius Ulna Pelvis Femur Patella Tibia Fibula Talus
What are the functions of the skeleton?
Support Protection Movement Structural shape and point of attachment Mineral storage Production of white blood cells.
Describe support as a function of the skeletal system.
The bones are solid and rigid. They keep us upright and hold the rest of the body, muscles and organs in place.
Describe protection as a function of the skeletal system.
Certain parts of the skeleton enclose and protect the body’s organs from external force (eg the heart and lungs are protected by the ribs).
Describe movement as a function of the skeletal system.
Helps the body move by providing anchor points for the muscle to pull against.
Describe shape as a function of the skeletal system.
Gives us a general shape such as height/build (somatotypes).
Describe mineral storage as a function of the skeletal system.
Bones store minerals including calcium and phosphorus which can be released into the blood.
Describe production of white and red blood cells as a function of the skeletal system.
Inner marrow of the long bones and ribs produce red and white blood cells. Red to carry oxygen and white to fight infection.
What are the 4 bone classifications?
Flat bones
Long bones
Short bones
Irregular
Describe flat bones.
Large and usually protect vital organs eg ribs and pelvis
Describe long bones.
Enable gross movement (large) eg femur.
Describe short bones.
Enables finer, controlled movements eg carpals and phalanges.
Describe irregular bones.
Specifically shaped to protect eg vertebrae designed to protect the spinal cord.
