synarthrosis/ fibrous joints

Answer 1

joints that do not move –> locked in place

Question 2

sutures (synathrosis)

Answer 2

• joints that closely connect things
  –> skull sutures

Question 3

syndesmosis (synarthrosis)

Answer 3

joints that join 2 bones by a membrane between them
–> the radius and ulna or the fibula and tibia

Question 4

amphiarthrosis/cartilaginous

Answer 4

joints that are somewhat moveable

Question 5

synchondroses (amphiarthrosis)

Answer 5

bones connected by hyaline cartilage
–> between ribs and sternum

Question 6

symphyses (amphiarthrosis)

Answer 6

bones connected by fibrocartilage
–> pubic symphysis

Question 7

diarthrosis/synovial

Answer 7

joints that are freely moveable

Question 8

synovial fluid (diarthrosis)

Answer 8

thick fluid found in the joint cavity that prevents friction between joints during movement

Question 9

joint cavity (diarthrosis)

Answer 9

space where two bones touch, holds synovial fluid

Question 10

bursae
