Applied Anatomy and Physiology Flashcards
What are the 6 functions of the skeleton?
Support Protection Movement Shape/Structure Mineral Storage Blood Cell Production
What is meant by Support in the function of the skeleton?
Support= The muscles and vital organs are all kept in place and supported by various parts of the skeleton.
What is meant by protection in the function of the skeleton?
Protection= This is mainly provided by the flat bones, protects vital organs,
What is meant by movement in the function of the skeleton?
Movement= The different types of joints allow different types of movement, as do the types of bones.
What is meant by shape/structure in the function of the skeleton?
Shape/structure is provided by the skeleton and the two types of bones also affect the amount of movement. Short bones enable finer controlled movements. Long Bones enable gross movements.
What is meant by mineral storage in the function of the skeleton?
Mineral Storage= the bones themselves are made of minerals and act as a mineral store for calcium and phosphorous, which can be given up if the body requires the minerals for other functions.
What is meant by blood cell production in the function of the skeleton?
Blood Cell Production= this takes place in the bone marrow where red blood cells are formed.
What is a synovial joint?
freely movable joints
What do Synovial joints allow us to do?
allow us the free movement to perform skills and techniques during physical activity.
What are tendons in a synovial joint?
Tendons= Very strong cords that attach the muscle to the bone.
What is the cartilage in a synovial joint?
Cartilage= tough, but flexible smooth elastic tissue which prevents friction and stops bones from rubbing together.
What is the Joint capsule in a synovial joint?
encloses and supports
What is the Bursae in the synovial joint?
Bursae= Sacks of fluid which reduce friction.
What is the synovial membrane in a synovial joint?
Synovial Membrane= Secretes synovial fluid
What is the synovial fluid in a synovial joint?
Synovial Fluid= provides lubrication tot he joint
What is the ligaments in a synovial joint?
Ligaments= bands of fibre which attach bone to bone
What are articulating bones?
Articulating Bones= Where two or more bones meet to allow movement at a joint.
What is a joint?
Joint- A connection point between two bones where movement occurs
What is abduction?
Abduction= Movement away from the mid line of the body
