The Skeletal System Flashcards
Name the five functions of the skeletal system
- Movement
- Protection
- Support
- Mineral storage
- Blood cell formation
What does the term articulation mean?
The joining of two or more bones
What is a tendon and what does it do?
A fibrous cord made up of collagen (a structural protein) that connects muscle to find.
It helps to absorb forces within the skeletal muscle and transfer these forces to bone to generate movement
What are ligaments? What is their purpose?
They are a fibrous band that primarily connects bone to bone.
By connecting bone to bone they help form a joint and keep that joint stabilised and supported during motion, preventing excessive joint articulations
What is connective tissue? What is it’s uses?
Tissue found all around the body that links body parts and other tissues (such as skin and muscle) together.
It also supports, protects and insulates and transports blood
What are the three types of joints?
Fibrous
Cartilaginous
Synovial
Describe what a fibrous joint is and an example
These are immovable joints, there is no movement between bones of fibrous joints. An example would be the joints that hold together the kill.
Describe cartilaginous joints and what is an example of one?
These joints allow for the connection of bones. Connection is entirely by cartilage. These joints allow for some degree of movement, more than fibrous joints but less than synovial joints. An example of this type of joint is the intervertebral discs of the spine
What are synovial joints and what is an example?
Synovial joints are highly moveable joints that make up most of he joints in the body. An example is relegated hip joint
What are the four types of synovial joints?
Pivot
Hinge
Saddle
Ball and socket
(Study and memorise the skeletal structure and major muscles on the two handouts)
Keep going over these until they become familiar
