Question 7

Plane joint

Answer 7

Synovial joint
Multiaxial gliding joint with flat articulating surface
Lesser ability to move than ball and socket because more bones and ligaments are in the way

Question 8

Muscle action analysis

Answer 8

1. Locate muscle and bony attachments
2. Determine joints crossed
3. Determine the type of joint and possible axes of rotation/movement
4. Determine the position of the muscle attachment in relation to the axes of rotation at the joint to determine possible movement and mechanical advantage
