Types Of Joints

Question 1

Fibrous Joints

Answer 1

• Immovable

- Held together by strong, fibrous connective tissue

Question 2

Examples of Fibrous joints

Answer 2

Sutures where the cranial bones meet

Question 3

Synovial Joints

Answer 3

• Contain fluid

- Freely movable

Question 4

Examples of Synovial Joints

Answer 4

Shoulder, elbows, wrists, hips, knees, ankles

Question 5

Cartilaginous Joints

Answer 5

• Slightly movable

- Held together by cartilage which allows partial movement

Question 6

Examples of Cartilaginous Joints

Answer 6

Joints between vertebrae

Question 7

Name the types of Synovial Joints

Answer 7

• Ball and socket joint
• Hinge joint
• Pivot joint
• Gliding joints

Question 8

Ball and socket joint

Answer 8

Bone with ball shaped head fits into the concave socket of the 2nd bone
Ex. Shoulders and hips

Question 9

Hinge joints

Answer 9

Move in one direction or plane

Ex. Knees, elbows, phalanges

Question 10

Pivot joints

Answer 10

Those with an extension rotate on a 2nd, arch shaped bone

Ex. Radius, ulna, atlas, and axis

Question 11

Gliding joints

Answer 11

Flat surfaces glide across each other

Ex. Carpals, tarsals

Question 12

How are Synovial Joints held together?

Answer 12

Ligaments (bands of connective tissue) hold the bones together at the joints. This prevents erosion from friction, there is a lubricating substance (“Synovial fluid”) in the joints
