The Skeletal System Flashcards
What Are Long Bones ?
- Long bones are strong and are used by muscles to assist movement, e.g the humerus in the arm.
- Used for larger gross movements, e.g moving the leg at the hip.
What Are Short Bones ?
- Support the weight of the body - they’re weight-bearing, e.g the tarsals in the foot.
- Used in some small and fine movements, e.g moving the hand at the wrist.
What Are Irregular Bones ?
- Are suited to protection and muscle attachment, e.g the vertebrae of the spine.
What Are Flat Bones ?
- They protect internal organs.
- Their broad surface also allows muscle attachment, e.g the ribs.
What Type Of Bone is Cranium & What Does It Protect ?
- Flat Bone
- Protects the brain
What Type Of Bone Are Both The Sternum & The Ribs And What Do They Protect ?
- Flat Bones
- Protect the heart and lungs.
- The ribs also protect the kidneys.
What Type Of Bone Is The Pelvis & What Does It Protect ?
- Flat Bone
- Protects the reproductive organs as well as the bladder.
- It also has many muscles attached to it, helping leg movement.
What Type Of Bone Are Carpals & What Does It Do ?
- Short Bones
- They form the wrist and give it stability allowing movement of the hand.
What Type Of Bones Are Tarsals & What Do They Do ?
- Short Bones
- Bear the body’s weight when on foot, e.g during standing and running
What Type Of Bone Is The Patella & What Does It Protect ?
- Sesamoid Bone
- Protects the tendon that crosses the knee joint by stopping it rubbing against the femur.
What Type Of Bone Is The Clavicle & What Does It Do ?
- Long Bone
- Forms part of the shoulder joint to assist arm movement.
What Type Of Bone Is The Humerus & How Is It Used ?
- Long Bone
- Used by muscles to move the whole arm, e.g swinging a badminton racket.
What Type Of Bones Are Both The Ulna And The Radius & How Are They Used ?
- Long Bones
- Used by muscles to move the lower arm, e.g bending at the elbow.
What Type Of Bone Is The Femur & How Is It Used ?
- Long Bone
- Used by muscles to move the whole leg, e.g when running.
What Type Of Bones Are Both The Fibula And The Tibia & How Are They Used ?
- Long Bones
- Used by muscles to move the lower leg, e.g to kick a football.
What Type Of Bone Is The Metacarpals & How Is It Used ?
- Long Bone
- Used by muscles to allow the hand to grip, e.g to hold a cricket bat.
What Type Of Bone Is The Phalanges & How Is It Used ?
- Long Bone
- Used by muscles to move and bend the fingers and toes.
