hinge joint
located at the knee and elbow. movement = flexion and extension
1 of 22
ball and socket joint
located at the hip and shoulder. movement = flexion, extension, rotation, abduction, adduction
2 of 22
flexion
WHEN THE ANGLE AT A JOINT DECREASES. this happens when the bones forming the joint move closer together. occurs at a hinge joint and a ball and socket joint.
3 of 22
extension
WHEN THE ANGLE AT A JOINT INCREASES. this happens when the bones forming the joint move away from each other. occurs at hinge joints and ball and socket joints
4 of 22
abduction
THE MOVEMENT OF A LIMB AWAY FROM THE MIDLINE OF THE BODY. occurs at ball and socket joints
5 of 22
adduction
THE MOVEMENT OF A LIMB TOWARDS THE MIDLINE OF THE BODY. occurs at ball and socket joints
6 of 22
rotation
WHEN THE BONE AT A JOINT MOVES AROUND ITS OWN AXIS, SO MAKING CIRCULAR MOVEMENT.
7 of 22
SIMPLE FRACTURE
or closed fractures, are where the bone does not break the skin
8 of 22
compound fracture
or open fractures, are where the broken bone causes the skin to break, adding an additional complication of possible infection
9 of 22
stress fracture
are injuries commonly caused by over-use. this is where a small crack forms in the bone.
10 of 22
greenstick fracture
are common in younger children. this is where the bone bends on one side and breaks on the other side.

tennis elbow
IS A JOINT INJURY WHERE THE TENDONS ARE INFLAMED. pain is felt on the OUTSIDE of the elbow. it can be caused by poor technique or over-use.
12 of 22
golfer's elbow
IS A JOINT INJURY WHERE THE TENDONS ARE INFLAMED. pain is felt on the INSIDE of the elbow. can be caused by poor technique or over-use
13 of 22
dislocation
IS WHERE ONE OF THE BONES AT A JOINT COMES OUT OF PLACE. it is very painful. often caused by a fall or blow to the area
14 of 22
sprain
IS A JOINT INJURY WHERE SOME OF THE FIBRES OF THE LIGAMENTS ARE TORN. happens when the joint goes througha greater range of movement that normal, tearing some of the fibres.
15 of 22
torn cartilage
IS A JOINT INJURY WHERE SMALL TEARS APPEAR IN THE CARTILAGE THAT ACTS AS A CUSHION TO THE END OF THE BONE. can occur from: forceful twisting, sudden impact/stopping. symptoms include: pain, swelling and stiffness at the joint
16 of 22
RICE
Rest Ice Compression Elevate = treatment for joint injuries to reduce pain and swelling
17 of 22
ANTAGONISTIC PAIRS
SKELETAL MUSCLES WORK TOGETHER TO PROVIDE MOVEMENT OF THE JOINTS. while one muscle CONTRACTS, another RELAXES to create movement
18 of 22
isotonic muscle contractions
THESE ARE CONTRACTIONS THAT RESULT IN MOVEMENT
19 of 22
isometric muscle contractions
THESE ARE WHERE THE MUSCLES CONTRACT BUT THERE IS NO VISIBLE MOVEMENT.
20 of 22
soft tissue injury
An injury to a muscle is called a MUSCLE SPRAIN. muscles can also suffer form deep bruising
21 of 22
muscle atrophy
can occur if muscles are not used due to injury or inactivity, this is where muscle mass decreases (the opposite to hypertrophy)
