Skeletal System Flashcards
How does the skeletal system create movement?
The skeleton provides an anchor point for the muscles to attach to.
Tendons join muscles to bones.
When bones meet they create a joint, this helps to create movement.
How is the skeletal system used for mineral storage?
The bones store minerals such as calcium and phosphorus and they are released into the blood stream. This helps maintain health.
How does the skeletal system provide protection?
Flat bones protects the vital organs to help prevent impact and injury whilst playing sport. For example, heading a football the cranium protects the brain.
How does the skeletal system provide support?
The bones are solid and rigid.
They keep us upright and hold the muscles and organs in place.
How do bones produce blood cells?
The inner marrow of long bones produces red and white blood cells.
Red blood cells carry oxygen to the muscles.
White blood cells help fight against infections.
What are synovial joints?
They are specifically designed to allow movement and prevent injury.
Two main types are ball and socket and hinge joints.
They consist of the bone, cartilage, tendon, muscle, bursae, ligament.
What movements does a ball and socket joint do?
Flexion- decrease of angle
Extension- increase of angle
Abduction- movement of a limb away from the midline of the body.
Adduction- movement of a limb towards midline of the body.
Circumduction- circular movement around the joint.
Rotation- turning around an axis/ fixed point.
What movement can be made at a hinge joint?
Flexion- decrease an angle
Extension- increase an angle
What movement can be made at the ankle joint?
Plantar flexion- angle of the joint increasing at the ankle
Dorsi flexion- angle of the joint decreasing at the ankle
