Question 0

Diarthrosis or synovial joint

Answer 0

Bone connected by a hallow sleeve of connective tissue proper.

• more common
• more mobile

Question 1

Synarthroses- what are its 2 subcategories? What are their functions?

Answer 1

Fibrous joints- solid mass. Least mobile joint. Connective tissue proper
-meniscus

Cartilage joints- bone connected by a solid mass of cartilage

Question 2

Interosseous membrane.

Answer 2

Bone joined by sheets of dense connective tissue.
-very strong
Found in radius, ulna, tibia, and fibula

Question 3

Syndesmosis

Answer 3

Bones joined by bands or thin layers of dense connective tissue.
Gomphosis- thin tissue that holds teeth together (in place).

Question 4

Sutures

What are the 4 types?

Answer 4

Plates that hold the skull together( where bones come together).
Shock absorption zones

4 types:
Plate sutures
Squamous sutures
Serrate sutures
Denticulate sutures

Question 5

Synchondrosis

Answer 5

Epiphyseal growth plate- held together with cartilage and found only in children.
~Allows bones to lengthen
~weakest part of the bone in a child
~can stunt growth if damaged.

Question 6

Symphysis
What are the 2 types?
What’s their functions?

Answer 6

Intervertebral discs- found in the spine

Symphysis pubis- found in pubic bone

Fibro cartilage
Absorbs shock
Strongest

Question 7

Synovial fluid

Answer 7

Lubricates and supply’s avascular articular cartilage with needed nutrients.

Question 8

Synovial membranes

Answer 8

Involved in secreting and absorbing the synovial fluid that is essential for the smooth operation of joints.
-Has blood in it

Question 9

Fiberous membrane or capsular ligament

Answer 9

Thickened continuation of the periosteum. Collagenous surrounding the spaces between neighboring bones.

• binds one bone to another
• connective tissue

Question 10

Ligaments

Answer 10

• Connects bone to bone
• does not contract
• dense regular
• all over

Question 11

Bursae

Answer 11

• small bags
• Outer Fibrous membrane
• dense irregular
• reduces friction between neighboring tissues

Question 12

Retinaculum

Answer 12

Collagenous bands of connective tissue that form tunnels through which multi joint tendons pass as they course into the hands and feet.
-holds the tendon in place and prevents it from being displaced.

Question 13

Synovial sheath

Answer 13

Protects the tendon from damage as it rubs against the neighboring bone and Retinaculum.
