Answer 1

1. Presence or absence of a joint cavity

2. Type of tissue uniting bones

Question 2

Suture

Answer 2

3. No joint cavity

(Example, Coronal suture)

Question 3

Gomphosis

Answer 3

1. Periodontal ligament
2. Small amount of dense connective tissue holding a tooth to its socket.
3. Synarthrotic

Question 4

Syndesmosis

Answer 4

1. Large amount of dense connective tissue
2. Amphiarthrotic

(Example: distal tibiofibular)

Question 5

Interosseous Membrane

Answer 5

1. Substantial sheet of dense conective tissue binding parallel long bones
2. Amphiarthrotic

(Example: between radius/ulna diaphyses and tibia/fibula diaphyses).

Question 6

Amphiarthrotic

Answer 6

Permitting slight movement in the joint

Question 7

Synarthrotic

Answer 7

Permitting no movement in the joint

Question 8

Synchondrosis

Answer 8

1. Hyaline cartilage unites bones
2. Synarthrotic

(Example: epiphyseal plate and between sternum/Rib 1)

Question 9

Symphysis

Answer 9

1. Fibrocartilage unites bones
2. Amphiarthrotic

(Example: Public symphysis and annulus fibrosis)

Question 10

Diarthrotic

Answer 10

Permitting free movement in the joint
