Question 1

reduction in bone density due to deossifiwcation, most prevalent in middle aged and elderly women

Answer 1

osteoporosis

Question 2

2 types of caritalage

Answer 2

hyaline and fibrocartilage

Question 3

3 components of articulations

Answer 3

bones, cartilage, fibrous (dense) connective tissue

Question 4

articulations are classifies by

Answer 4

degree of movement

Question 5

immovable

Answer 5

synarthrosis

Question 6

slightly movable

Answer 6

amphiarthrosis

Question 7

freely movable

Answer 7

diarthrosis

Question 8

bones fastened together by thin bands of fibrous connective tissue

Answer 8

fibrous structure

Question 9

joint consists of broad fibrous bands to form interosseous ligament; movement classification = amphiathorosis

Answer 9

syndesmosis

Question 10

only between flat bones of the skull (sutural ligament); movement classification = synarthrosis

Answer 10

suture

Question 11

articulation between tooth root and bony socket (periodontal ligament); synarthrosis

Answer 11

gomphosis

Question 12

connection consist of hyaline cartilage and/or fibrocartilage

Answer 12

cartilaginous

Question 13

bones united by a plate of hyaline cartilage; movement classification = synarthrosis (1st rib and sternum)

Answer 13

synchondrosis

Question 14

bone articular surfaces covered by hyaline cartilage, which in turn is attached to a thick pad of fibrocartilage; classification = amphiarthrosis

Answer 14

symphysis

Question 15

space between articulating bones filled with synovial fluid

Answer 15

synovial space

Question 16

articular ends of bone covered with thin layer of hyaline cartilage

Answer 16

articular cartilage

Question 17

fibrous outer layer contiguous with periosteum of bones

Answer 17

fibrous joint capsule (fibrous layer, capsular ligament)

Question 18

thin inner layer covering all non cartilaginous surfaces

Answer 18

synovial membrane

Question 19

secreted by synovial membrane, filling synovial cavity

Answer 19

synovial fluid

Question 20

fibrocartilage pad located between articular surfaces

Answer 20

articular disk (meniscus of the knee)

Question 21

closed fluid-filled sac

Answer 21

bursa

Question 22

globular /spherodial surface of one bone articulates with a cup shaped surface of another bone; triaxial

Answer 22

ball and socket (a.k.a. spherodial)

Question 23

convex oval-shaped of one bone articulates with a concave elliptical surface of another nine; biaxial

Answer 23

condyloid (a.k.a. ellipsoidal)

Question 24

articulating surfaces have both concave and convex regions; surface of one bone fits complimentary surface of another; biaxial

Answer 24

saddle (a.k.a. sellar)
