Movements at synovial joints

Question 1

the angle between the two bones decreases ~(movement and example)

Answer 1

Flexion - EG, elbow on the upwards phase of a bicep curl.

Question 2

The angle between the two bones increase

Answer 2

Extension - EG, knee - straightening the leg when kicking a football

Question 3

the angle between the front of the leg and foot increases/decreases

Answer 3

Plantarflexion/dorsiflexion - EG, Ankle - taking off on jump/pulling toes towards knees during a jump

Question 4

sideways movement away from the midline of the body

Answer 4

lateral flexion - EG, Vertebrae, bending sideways to make a save

Question 5

movement of a body part across the body away from the midline

Answer 5

horizontal extension - eg, shoulder movement of arm forward

Question 6

movement of a body part across the body horizontally towards the midline

Answer 6

horizontal flexion - Eg, Shoulder - movement of arm forwards in flexionwhen bowling underarm

Question 7

the angle between two bones is increased beyond the normal range of motion

Answer 7

Hyperextension - EG, vertebrae, beding backwards to make a tennis smash

Question 8

a body part is moved away from the midline

Answer 8

abduction - Eg, shoulder/hip while doing starjumps

Question 9

a body part is moved towards the midline of the body

Answer 9

adduction - Eg, shoulder/hip while doing starjumps

Question 10

the movement of a body part around its axis

Answer 10

rotation - Eg, hip, externally turning foot outwards to receive a pass

Question 11

circular motion of a limb at a joint

Answer 11

circumduction - shoulder during butterfly stroke

Question 12

functions of synovial fluid ?

Answer 12

lubrication for the joint, nourishes
reduces friction between bones by stopping them rubbing together
used as a shock absorber
