Question 1

Three Principal Types of Joints

Answer 1

1) Fibrous
2) Cartilaginous
3) Synovial

Question 2

Suture

Answer 2

The bones are connected by a dense layer of fibrous tissue that binds to the periosteum of each element. These are found in the skull.

Question 3

Syndesmosis

Answer 3

The bones are connected by short collagenous interosseous ligaments. Examples are the shafts of the radius and ulna, the shafts of the tibia and fibula, and the distal ends of the tibia and fibula.

Question 4

Gomphosis

Answer 4

This joint is between the teeth and the bones of the face (maxilla and mandible). The tooth root is connected to the walls of its socket by periodontal ligaments.

Question 5

Synchondrosis

Answer 5

The bones are connected by a plate of hyaline cartilage. This kind of joint is found between the metaphysis and epiphysis of a growing bone. The intervening hyaline cartilage forms the growth plate.

Question 6

Symphysis

Answer 6

The bones are connected by a pad of fibrocartilage, which permits a limited amount of movement. Examples are the public symphysis of the pelvis and the intervertebral discs.

Question 7

Fontanelles

Answer 7

Soft spots which decrease in size as the infant’s head grows.
