Flashcards in the role of the skeletal system Deck (7)
What type of joints are there?
Freely movable — the majority of joints fall into this category and are known as synovial.
Slightly movable — a good example of this is the vertebrae in the spine.
Immovable — there is no movement here, such as the bones that make up the skull.
What are the names given to the specific movements?
Flexion; extension; abduction; adduction; rotation.
What is flexion?
The decreasing of an angle at a joint, such as bending the arm at the elbow.
What is extension?
The opposite movement to flexion where the angle at a joint is increased, such as straightening the arm at the elbow.
What is abduction?
The movement of a bone or limb away from the midline of the body, such as the first movement of a star jump with the arms and the legs.
What is adduction?
The opposite movement to abduction where the bone or limb moves towards the body, such as the return of the movement of the arms and legs when performing a star jump.
