SYNOVIAL JOINTS

SYNOVIAL JOINTS

• YEAR 10 GCSE

2
Lesson Objectives

• You will know five different synovial joints.
• You will be able to identify where in the body
  these synovial joints are.
• You will understand how these joints help our
  body to move.
• You will be able to identify synovial joints on a
  sports person.

3
CONDYLOID JOINT

• Movement is possible in two planes.
• The rounded end of one bone fits into the hollow
  of another.
• Movement is back and forward and side- to side.
• Ligaments prevent rotation.
• Example wrist

4
PIVOT JOINT

• Only rotation is possible because it has a ring
  on a peg structure.
• Example between the atlas and axis vertebrae in
  the neck.

5
HINGE JOINT

• Movement in one plane only.
• Will open until it is straight.
• Movement is limited because of the shape of the
  bones and the position of the ligaments.
• Example elbow.

6
BALL SOCKET JOINT

• Moves freely in all directions.
• Ligaments are often used to keep the joint
  stable.
• Examples hip shoulder.

7
GLIDING JOINT

• One bone slides on top of another.
• A little movement is possible in all directions.
• Ligaments limit the movement.
• Example Carpal Bones (hand).

8
Your Task

• Label the 5 synovial joints neatly onto the
  sports person with a full description. Use page
  19 to help you!
• Add the range of movement the joint allows. Use
  the table on page 20 to help you!
• eg hinge flexion extension.

9
Muscular System

• Complete Muscle Sheet (Page 23).
• Add different colours to make different muscles
  stand out.
• Revise muscles for short test at the start of
  next lesson.
