Skeletal System Flashcards
Name the two types of synovial joints
Hinge
Ball and socket
What are flat bones?
Often large and usually protect vital organs
What are long bones?
Enable gross (large) movements
What are short bones?
Enable finer, controlled movements
What are irregular bones?
Irregular bones are specifically shaped to protect. E.g. Vertebrae designed to protect the spinal cord
What are the functions of the skeleton?
Support Protection Movement Structural shape Blood cell production Storage of minerals
What is the function of support?
Keep the body upright
What is the function of protection?
The bones of the skeleton protect the internal organs and reduce the risk of injury on impact. When you head the ball in football, you are protecting the brain.
What is the function of movement?
The bones act like levers and also form joints that allows muscles to pull on them and produce joint movements
What is function of structural shape?
The skeleton provides the human shape and determines the height of a shape
What is the function of blood cell production?
Certain bones in the skeleton contain red bone marrow and the bone marrow produces red blood cells, white blood cells and platelets.
What is the function of storage of minerals?
The bones themselves are made of minerals and act as a mineral store for calcium and phosphorus
