Question 8

syndesmoses

Answer 8

joined by sheet of fibrous tissue band

e.g. interosseous ligament

Question 9

sutures

Answer 9

interlocking projections of adjacent bone plates, joined by a thin layer of fibrous tissue

Question 10

gomphoses

Answer 10

joint connected by a layer of fibrous tissue - peridontal membrane
e.g. tooth

usually temporary - during growth
between epiphysis and diaphysis

Question 15
