Chapter 8 - Articulations

Question 0

Classification of functional movements?

Answer 0

1. Synathrosis - immovable
2. Amphiarthrosis - slightly movable
3. Diarthrosis - very movable

Question 1

What are the different ways to classify articulations/joints?

Answer 1

Functional and structural

Question 2

Classification of structural articulations bases on presence/absence of synovial cavity?

Answer 2

1. Fibrous joints - no synovial cavity held together by fibrous CT
2. Cartilage joints - no synovial cavity held together by cartilage
3. Synovial joints - held together by articulations capsule

Question 3

What are the types of fibrous joints?

Answer 3

1. Sutures - between bones of skull (serrated, squamous, plane)
2. Syndesmosis - held together by interosseous membrane
3. Gomphosis - between teeth and bone, cone shaped

Question 4

What are the types of cartilaginous joints?

Answer 4

1. Synchondrosis - hyaline cartilage (between first rib and sternum)
2. Symphysis - flat disc (vertebrae)

Question 5

What are the synovial joints?

Answer 5

• articulations cartilage : covers bone ends (hyaline cartilage)
• articular capsule : sleeve-like structure (fibrous outside, synovial inner)

Question 6

What are factors that affect movement?

Answer 6

Fit of bones, ligaments, muscles, apposition of soft body parts

Question 7

What are the types of movements?

Answer 7

1. Gliding
2. Angular - changes in anatomical position
3. Rotation - movement of bone around own axis
4. Circumspection - distal end moves in a circle
