Answer 1

skull, vertebra, ribs, sternum

Question 2

parts of appendicular skeleton

Answer 2

limbs

Question 3

fibrous joint

Answer 3

immovable, bones are united by fibrous tissue
(between skull bones, splint and cannon bones)

Question 4

cartilaginous joint

Answer 4

slightly movable
(between 2 halves of pelvis, mandible, and adjacent vertebrae)

Question 5

characteristics of cartilage (4)

Answer 5

-dense connective tissue
-absorbs shock
-protects the ends of bones
-no nerves or blood supply (resistant to pain)

Question 6

synovial joint

Answer 6

freely movable, majority of joints in body (shoulder and stifle joints)

Question 7

synovial joint characteristics (5)

Answer 7

-articular surfaces
-articular cartilage
-joint cavity
-joint capsule
-ligaments

Question 8

types of synovial joint movements (6)

Answer 8

-flexion
-extension
-abduction
-adduction
-rotation
-circumduction

Question 9

flexion joint movement

Answer 9

making the angle between bones smaller

Question 10

extension joint movement

Answer 10

making the angle between bones larger

Question 11

abduction joint movement

Answer 11

moving away from median plane

Question 12

adduction joint movement

Answer 12

moving towards median plane

Question 13

rotation joint movement

Answer 13

twisting motion of a part on its own axis

Question 14

circumduction joint movement

Answer 14

motion of an extremity in a circle

Question 15

hinge joint

Answer 15

only allows flexion and extension

Question 16

Types of Synovial Joints

Answer 16

-hinge
-gliding/rocking
-pivot
ball and socket

Question 17

gliding/rocking joints

Answer 17

joint surfaces relatively flat, allow flexion, extension (livestock), adduction (minimal in livestock), and abduction

Question 18

pivot joints

Answer 18

one bone pivots or rotates around another
(joint between 1st and 2nd vertebrae in neck, shaking head “no”)

Question 19

ball and socket joints

Answer 19

allows most extension
