joints

Question 1

synovial joints

Answer 1

allow motion to occur between two bones, which makes synovial joints much less stable than either fibrous or cartilaginous joints

Question 2

cartilaginous joints

Answer 2

bones united by cartilage, which may be hyaline cartilage or fibrocartilage.

Question 3

plane joint

Answer 3

flat articular surfaces that allow the bones to glide past one another

Question 4

condyloided joint

Answer 4

fits into the concave surface of another bone

Question 5

saddle joint

Answer 5

resemble condyloid joints but permit a greater range of motion

Question 6

hinge joint

Answer 6

the convex articular surface of one bone fits into a concave articular surface of another bone.

Question 7

pivot joint

Answer 7

consist of one bone with a rounded projection that fits into a groove of another bone

Question 8

ball and socket

Answer 8

ball-like end of one bone that fits into the concave “socket” of another bone

Question 9

articular cartilage

Answer 9

covers articulating ands of bones

Question 10

joint capsule

Question 11

ligaments

Answer 11

cords of dense collagenous connective tissue, which further reinforce the joint.

Question 12

articular discs

Answer 12

fibrocartilage pads that improve the fit of two bones to prevent dislocation

Question 13

non axial joint

Answer 13

bones glide past eachother

Question 14

uniaxial joint

Answer 14

allow motion in one plane or direction around a single axis

Question 15

biaxial joint

Answer 15

Joints that allow motion in two planes around two axes of motion

Question 16

multiaxial joints

Answer 16

allow motion in multiple planes around all three axes

Question 17

symphois

Answer 17

the bones are joined by a tough cartilaginous pad. Examples include the intervertebral joints and the pubic symphysis.

Question 18

Synchondroses

Answer 18

consist of bones joined by hyaline cartilage

Question 19

Ligaments

Answer 19

bones in a synovial joint are held together by ligaments, cords of dense collagenous connective tissue, which further reinforce the joint

Question 20

Anterior cruciate ligament

Answer 20

extends from the anterior tibial plateau to the posterior part of the lateral femoral condyle

Question 21

Posterior cruciate ligament

Answer 21

extends from the posterior tibial plateau to the anterior part of the medial femoral condyle. It crosses under the ACL, and the two together form an “X.”

Question 22

Tibial collateral ligament

Answer 22

extends from the medial tibia to the medial femur. It resists stresses that pull the tibia laterally on the femur.

Question 23

Fibular collateral ligament

Answer 23

extends from the lateral fibula to the lateral femur. It resists stresses that pull the tibia medially on the femur.
