Lecture Exam 2 - Joints

Question 1

The functional classifications of joints

Answer 1

Synarthroses
Amphiarthroses
Diarthroses

Question 2

Synarthroses

Answer 2

immovable joints

Question 3

Amphiarthroses

Answer 3

slightly movable joints

Question 4

Diarthroses

Answer 4

Freely movable joints

Question 5

the structural classifications

Answer 5

fibrous
cartilaginous
synovial

Question 6

fibrous joints types

Answer 6

suture
syndesmosis
gomphosis

Question 7

suture

Answer 7

held together with very short, interconnecting fibers and bone edges interlock
• Only in the skull

Question 8

syndesmosis

Answer 8

held together by a ligament. Fibrous tissue can vary in length but is longer than in sutures
• Fibula + tibia
• Little to no movement allowed (short fibers), lots of movement (long fibers)

Question 9

gomphosis

Answer 9

peg-in-socket fibrous joint. Periodontal ligament holds tooth in socket
• Teeth

Question 10

types of cartilaginous joints

Answer 10

Synchondroses

symphyses

Question 11

synchondroses

Answer 11

bones united by hyaline cartilage
• Epiphyseal plates
• Between the first rib’s costal cartilage and the manubrium of the sternum

Question 12

symphyses

Answer 12

bones united by fibrocartilage, slightly movable joints that provide strength with flexibility
• Intervertebral discs, pubic symphysis of pelvis, articular cartilage on bony surfaces
• Articular cartialges – reduce friction between the bones during movement
