60
Q

What type of joint movement is it when the angle at a joint decreases?

A

Flexion

61
Q

What type of joint movement is it when the angle at a joint increases?

A

Extension

62
Q

In which 2 types of joint does flexion occur?

A

Hinge Joints and Ball and Socket joints

63
Q

In which 2 types of joint does extension occur?

A

Hinge Joints and Ball and Socket joints

64
Q

FLEXION: Give an example of a sport and a skill in that sport and a joint where flexion occurs. Also describe what happens to body parts on either side of the joint.

A

Football, at the knee, preparing to kick a ball. As the ANGLE DECREASES as it does in FLEXION movement, the LOWER part of the LEG, gets CLOSER to the UPPER part of the LEG. Visualise your leg moving and it becomes common sense!

65
Q

EXTENSION: Give an example of a sport and a skill in that sport and a joint where extension occurs. Also describe what happens to body parts on either side of the joint.

A

Football, at the knee, following through after kicking a ball. As the ANGLE INCREASES as it does in EXTENSION movement, the LOWER part of the LEG, gets FURTHER AWAY from the UPPER part of the LEG. Visualise your leg moving and it becomes common sense!

66
Q

What happens to the bones that form a joint when FLEXION occurs? Also say what happens to the ANGLE at the joint.

A

When FLEXION occurs, the angle at the joint DECREASES which means that the bones in the joint move CLOSER TOGETHER.

67
Q

What happens to the bones that form a joint when EXTENSION occurs? Also say what happens to the ANGLE at the joint.

A

When EXTENSION occurs, the angle at the joint INCREASES which means that the bones in the joint move AWAY FROM EACH OTHER.

68
Q

What does range of movement mean? Give an example.

A

Range of movement means that there is more than one type of movement. For example, the range of movement at the elbow is flexion to extension.

69
Q

What type of movement is the movement of a limb away from the body?

A

Abduction

70
Q

What type of movement is the movement of a limb towards the body?

A

Adduction

71
Q

What type of movement is when the bone at a joint moves around its own axis (single axis) in a circular movement?

A

Rotation. Be careful not to confuse with circumduction which is the combination of 4 types of movement and therefore along MORE THAN 1 axis. Rotation occurs on ONE AXIS, only.

72
Q

What type of joint is a circular movement that is the combination of several types of movement?

A

Circumduction

73
Q

In which type of joint does ABDUCTION occur?

A

Ball and Socket

74
Q

In which type of joint does ADDUCTION occur?

A

Ball and Socket

75
Q

In which type of joint does ROTATION occur?

A

Ball and Socket

76
Q

In which type of joint does CIRCUMDUCTION occur?

A

Ball and Socket

77
Q

Give an example of a sport, the joint, and a skill in that sport where ABDUCTION happens.

A

Netball or Basketball, shoulder, reaching out sideways to intercept the ball

78
Q

Give an example of a sport, the joint, and a skill in that sport where ADDUCTION happens.

A

Javelin, hip, cross-over leg action when throwing

79
Q

Give an example of a sport, the joint, and a skill in that sport where ROTATION happens.

A

Swimming, shoulder, arm rotating forward

80
Q

Give an example of a sport, the joint, and a skill in that sport where CIRCUMDUCTION happens.

A

Cricket; shoulder, bowling

81
Q

What type of movement is the bending of the foot downwards away from the tibia?

A

Plantarflexion

82
Q

What type of movement is the bending of the foot upwards away from the tibia?

A

Dorsiflexion

83
Q

At which joint does PLANTARFLEXION occur?

A

The ankle

84
Q

At which joint does DORSIFLEXION occur?

A

The ankle

85
Q

Give an example of an action in a sport that involves PLANTARFLEXION.

A

Football; Striking ball with instep

86
Q

Give an example of an action in a sport that involves DORSIFLEXION.

A

Football, Bending the foot upwards to trap the ball with the side of your boot.

87
Q

At which joint does ELEVATION occur?

A

The shoulder

88
Q

At which joint does DEPRESSION occur?

A

The shoulder

89
Q

ELEVATION and DEPRESSION are two types of joint movements that occur in which TYPE of joint. (Say the TYPE, not the joint itself.)

A

Ball and socket. (Specifically the shoulder.)

90
Q

What range of movement can happen at the ankle?

A

PLANTARFLEXION and DORSIFLEXION. Remember: RANGE OF MOVEMENT discussions have to have two or more types of joint movements in order for it to be a ‘range’.

91
Q

Give an example of an action in a sport that involves ELEVATION and DEPRESSION.

A

Weightlifting. Standing up, holding the free weights or bar weight at your shoulder. Press up so that arms are straight up uses ELEVATION of the shoulder joint, and bringing it back down uses DEPRESSION of the shoulder joint.

92
