The Musculo-Skeletal System ( Paper 1) (Miss Kieser)

Question 1

What are the 5 different types of joints ?

Answer 1

• Ball and Socket Joint
• Hinge Joint
• Gliding Joint
• Condyloid Joint
• Pivot Joint

Question 2

Give me some information about the Gliding joint ?

Answer 2

occurs between the surfaces of 2 flat bones that are held together by ligaments. It is important for sports as these joints are used for flexibility
and movement in the hands, feet and back regions

Question 3

Give me some information about the Condyloid Joint ?

Answer 3

allow small movement in all directions, these joints are important when a sport involves gripping a ball

Question 4

Give me some information about the Pivot Joint ?

Answer 4

allows rotation only, important for sport because this joints allow for small movements that support a larger sporting action.

Question 5

Give me some information about the ball and socket joint ?

Answer 5

these are found in the hips and shoulders and allows for all type of movement to occur.

Question 6

Give me some information about the hinge joint ?

Answer 6

these are found in the elbows and knees and they allow flexion and extension

Question 7

What is a agonist ?

Answer 7

the contracting muscle responsible for causing movement.

Question 8

What is a antagonist ?

Answer 8

the lengthening muscles which allows the movement to occur

Question 9

What is a isometric contraction ?

Answer 9

this is when the muscles contracts without lengthening or shortening

Question 10

What is a Isotonic contraction ?

Answer 10

this is when the muscle lengthens or shortens when contracts

Question 11

What is a concentric contraction ?

Answer 11

this is where the muscles shortens when contracts

Question 12

What is an eccentric contraction ?

Answer 12

this is where the muscles lengthen when it contracts

Question 13

Describe the movement extension ?

Answer 13

involves an increase in the angle that occurs around a
joint.

Question 14

Describe the movement flexion ?

Answer 14

involves a decrease in the angle that occurs around a
joint.

Question 15

Describe the movement plantar flexion ?

Answer 15

It involves bending the foot downwards, away from the tibia.

Question 16

Describe the movement dorsi flexion ?

Answer 16

is bending the foot upwards towards the Tibia.

Question 17

Describe the movement adduction ?

Answer 17

Movement towards midline of the body

Question 18

Describe the movement abduction ?

Answer 18

Movement away from midline of the body

Question 19

Describe the movement horizontal adduction ?

Answer 19

Movement of the arm across the body in the horizontal plane.

Question 20

Describe the movement horizontal abduction ?

Answer 20

Movement of the arm away from the body in the horizontal
planeWhat

Question 21

What are the 3 planes ?

Answer 21

• Sagittal
• Frontal
• Transverse

Question 22

What is the sagittal plane ?

Answer 22

divides the body into left and right sides, it allows forwards and backwards movements

Question 23

What is a sporting example of a sagittal plane ?

Answer 23

front somersault

Question 24

What is a frontal plane ?

Answer 24

this divides the body into front and back. It allows side to side movements

Question 25

What is a sporting example of a frontal plane ?

Answer 25

a star jump

Question 26

What is a transverse plane ?

Answer 26

divides the body into lower and upper halves. It allows for rotational or turning movements.

Question 27

What is a sporting example of a transverse plane ?

Answer 27

ice skating spin

Question 28

What are the 3 different axes ?

Answer 28

• Sagittal axis
• Longitudinal axis
• Transverse axis

Question 29

What it is a longitudinal axis ?

Answer 29

runs through the body vertically from top to bottom

Question 29

What is a sagittal axis ?

Answer 29

it runs through the body horizontally from back to front

Question 30

What is a transverse axis ?

Answer 30

runs through the body horizontally from left to right
