slight movement

Question 5

What is the functional classification of synovial?

Answer 5

a lot of movement

Question 6

What is the structural class of fibrous joints? + examples

Answer 6

• fibrous connective tissue
• joints are held in place therefore very strong
• bone will break first before joint gives way
• e.g. sutures, gomphosis
