THE SKELETAL SYSTEM

Question 1

WHAT ARE THE DIFFERENT FUNCTIIONS OF THE SKELETON

Answer 1

1) SUPPORT/SHAPE
2) PROTECTION
3) MOVEMENT
4) MAKING BLOOD CELLS/PLATELETS
5) MINERAL STORAGE

Question 2

HOW DOES THE SKELETON SUPPORT AND SHAPE

Answer 2

1) THE SKELETON IS A RIGID BONE FRAME FOR THE REST OF THE BODY, OUR SHAPE IS MAINLY DUE TO OUR SKELETON
3) THE SKELETON SUPPORTS THE SOFT TISSUES LIKE SKIN AND MUSCLD
4) IT HELPS YOU TO HAVE A GOOD POSTURE WHICH IS ESSENTIAL IN LOADS OF SPORTS

Question 3

HOW DOES THE SKELETON MOVE

Answer 3

1) MUSCLES, ATTACHED TO BONES BY TENDONS, CAN MOVE BONES AT JOINTS
2) THIS MOVEMENT IS ESENTIAL FOR GOOD PERFORMANCE IN SPORT
3) THERE ARE DIFFERENT TYPES OF MOVEMENT AT THE VARIOUS JOINTS, WHICH ARE IMPORTANT IN DIFFERENT SPORTS

Question 4

HOW DOES THE SKELETO PROTECT

Answer 4

1) BONES ARE VERY TOUGH- THEY PROTECT VITAL ORGANS LIKE THE BRAIN, HEART AND LUNGS
2) THIS ALLOWS TO PERFORM WELL IN SPORT WITHOUT FEAR OF SERIOUS INJURY

Question 5

HOW DOES THE SKELETON MAKE BLOOD CELLS/PLATELETS

Answer 5

1) SOME BONES CONTAIN BONE MARROW, WHICH MAKES THE COMPONENTS OF BLOOD- PLATELETS AND RED AND WHITE BLOOD CELLS
2) RED BLOOD CELLS ARE REALLMY IMPORTANT DURING EXERCISE BECAUSE THEY TRANSPORT OXYGEN THAT MUSCLES NEED. TO MOVE
3) ATHLETES WITH MORE RED BLOOD CELLS PERFORM BETTER

Question 6

HOW IS THE SKELETON A MINERAL STORAGE

Answer 6

1) BONES STORE MINERAKS LIKE CALCIUM AND PHOSPHORUS
2) THESE HELP WITH BONE STRENGTH SO YOU ARE LESS LIKELY TO BREAK A BONE
3) THEY ARE ALSO NEEDED FOR MUSCLE CONTRACTION SO THAT THE BODY CAN MOVE

Question 7

WHAT ARE THE DIFFERENT TYPES OF BONE IN THE SKELETON

Answer 7

1) LONG BONES
2) SHORT BONES
3) IRREGULAR BONES
4) FLAT BONES

Question 8

CHARACTERISTICS OF LONG BONES

Answer 8

LONG BONS FOR EXAMPLE (HUMERUS IN THE ARM) ARE STRONG AND ARE USED BY MUSCLES TO ASSIST MOVEMENT

Question 9

CHARACTERISTICS OF SHORT BONES

Answer 9

SHORT BONES FOR EXAMPLE THE TARSALS IN THE FOOT, SUPPORT WEIGHT OF THE BODY

Question 10

CHARACTERISTICS OF IRREGULAR BONES

Answer 10

IRREGULAR BONES, FOR EXAMPLE VERTEBRAE OF THE SPINE, ARE SUITED TO PROECTION AND MUSCLE ATTACHEMENT

Question 11

CHARACTERISTICS OF FLAT BONES

Answer 11

FLAT BONES, FOR EXAMPLE THE RIBS, PROTECT INTERNAL ORGANS, THEIR BROAD SURFACE ALLOWS MUSCLE ATTACHEMENT

Question 12

THERE ARE DIFFERENT KINDS OF JOINT MOVEMENT, WHAT ARE THE EIGHT JOINT MOVEMENT:

Answer 12

1) FLEXION
2) EXTENSION
3) ADDUCTION
4) ANDUCTION
5) ROTATION
6) CIRCUMDUCTION
7) PLANTAR-FLEXION
8) DORSI-FLEXION

Question 13

WHAT IS FLEXION

Answer 13

CLOSING A JOINT- EG: WRIST MOVEMENT DURING A BASKETBALL THROW

Question 14

WHAT IS EXTENSION

Answer 14

OPENING A JOINT- EG: KICKING A FOOTBALL

Question 15

WHAT IS ADDUCTION

Answer 15

MOVING TOWARDS AN IMAGINARY CENTRE LINE- EG: SWINGING A GOLF CLUB

Question 16

WHAT IS ABDUCTION

Answer 16

MOVING AWAY THE IMAGINARY CENTRE LINE- EG: BRINGING BACK A TENNIS RACKET BEFORE SWINGING IT

Question 17

WHAT IS ROTATION

Answer 17

CLOCKWISE OR ANTICLOCKWISE MOVEMENT- EG: THE LEG MOVEMENT DURING A TURNOUT IN BALLET

Question 18

WHAT IS CIRCUMDUCTION

Answer 18

MOVEMENT OF A LIMB, HAND OR FOOT IN A CIRCULAR MOTION- EG: THE BOWL A CRICKET BALL

Question 19

WHAT IS PLANTAR-FLEXION

Answer 19

EXTENSION AT THE ANKLE- EG: POINTING TOES DURING GYMNASTICS

Question 20

WHAT IS DORSI-FLEXION

Answer 20

FLEXION AT THE ANKLE- EG: LIFTING TOES DURING GYMNASTICS

Question 21

WHICH ARE THE FOUR JOINT IMPORTANT TYPES

Answer 21

1) BALL AND SOCKET- HIP, SHOULDER
2) HINGE- KNEE, ANKLE, ELBOW
3) CONDYLOID- WRIST
4) PIVOT- NECK

Question 22

WHICH ARE THE THREE IMPORTANT CONNECTIVE TISSUES

Answer 22

1) CARTILAGE
2) LIGAMENTS
3) TENDONS

Question 23

WHAT IS THE CARTILAGE

Answer 23

IT ACTS AS A CUSHION BETWEEN BIONES TO PREVENT DAMAGE DURING JOINT MOVEMENT

Question 24

WHAT ARE LIGAMENTS

Answer 24

THEY HOLD BONES TOGETHER TO HELP MAINTAIN THE STABILITY OF THE SKELETON DURING MOVEMENT

Question 25

WHAT ARE TENDONS

Answer 25

THEY ATTACH MUSCLES TO BONES (OR TO OTHER MUSCLES) TO ALLOW BONES TO MOVE WHEN MUSCLES CONTRACT
