Chapter 9 Quiz Questions

Question 1

What are the 3 structural classification joints?

FCS

Answer 1

1. Fibrous joint
2. Cartilaginous joint
3. Synovial joint

Question 2

What are the 3 types of functional joints?

Answer 2

1. Synarthroses (immovable)
2. Amphiarthroses (slightly movable)
3. Diarthroses (Freely movable joints)

Question 3

Describe a fibrous joint, and identify its three types.

SSG

Answer 3

It is a joint where the adjacent bones are united by fibrous connective tissue.

1.Suture
2. Syndesmosis
3. Gomphosis

Question 4

What are two types of cartilaginous joints and examples of them?

4 syllables + think of photosynthesis

Answer 4

1. Synchondrosis (Epiphyseal Plate)
2. Symphysis (Intervertebral disks)

Question 5

Identify 2 layers that make up the articular capsule of a synovial joint

Think of card #1 (1 and 3)

Answer 5

1. Outermost fibrous membrane of dense irregular connective tissue
2. An inner synovial membrane of areolar connective tissue.

Question 6

What is articular cartilage?

Answer 6

The hyaline cartilage that covers the articulating surfaces of the bones in a synovial joint.

Question 7

What are articular disks? What is their function?

Answer 7

They are pads of fibrocartilage found in some synovial joints. They help to stabilize the joint.

Question 8

What are the 5 types of movements?

Answer 8

1. Gliding
2. Flexion
3. Extension
4. Rotation
5. Dorsiflexion

Question 9

Describe each type of movement.

Answer 9

Gliding –> movement of one surface over another w/o angular or rotational movement.

Flexion –> Involves a decrease in angle between anterior surfaces of articulating bones.

Extension –> Usually involves an increase in the angle between anterior surfaces of articulating bones.

Rotation –> Movement around a longitudinal axis

Dorsiflexion –> Flexion of foot at the ankle
