Chapter 9: joints; types of synovial joints associated with movement

Question 1

Types of synovial joints

Answer 1

shapes of bone surfaces at joint determines types of movements allowed

Question 2

Nonaxial synovial joint (non axial movement)

Answer 2

plane joints, relatively flat articular surfaces that are gliding or sliding over each other over no particular axes. These are the most common types of synovial joints

examples; intercarpal joints, intertarsal joints, intervertebral joints between superior and inferior articular processes

Question 3

uniaxial movement synovial joint

Answer 3

there are two types hinge joints and pivot joints.

The only allow free movement over 1 axis. They are the most limited synovial joints in range of possible movements

Question 4

patellar ligament/tendon (knee joint structure)

Answer 4

from patella to tibial tuberosity

Question 5

Quadriceps tendon (knee joint structure)

Answer 5

from quadriceps muscles to patella

Question 6

Hinge joints (uniaxial movement synovial joint)

Answer 6

allow flexion and extension movements over 1 axis;

examples: elbow joints, interphalangeal joints, knee joints

Question 7

fibular/lateral collateral ligament (knee joint structure)

Answer 7

from femur to fibula

Question 8

tibial/medial collateral ligament

Answer 8

from femur to tibia

Question 9

anterior cruciate ligament/ACL

Answer 9

helps tibia from slipping interiorly

Question 10

posterior cruciate ligament/PCL

Answer 10

helps tibia from slipping posteriorly

Question 11

lateral and medial meniscus

Answer 11

form articular disc of knee joint

Question 12

Pivot joints (uniaxial movement)

Answer 12

allow for rotation movements over 1 axis

examples: proximal radioulnar joints, atlantoxial joint between atlas and axis

Question 13

Biaxial movement

Answer 13

allow for flexion, extension and adduction/abduction over 2 axes.

Question 14

how many types of biaxial movements are there?

Answer 14

two types

Question 15

Condylar joints (biaxial movement)

Answer 15

articular surfaces are oval in shape;

examples: metacarpophalangeal joints, wrist joints

Question 16

Saddle joints (biaxial movement)

Answer 16

articular surfaces are shaped like saddles;

examples: trapezium to metacarpal 1

Question 17

multiaxial movement

Answer 17

allow for free movement over 3 axes; flexion and extension, adduction and abduction, rotation

Question 18

ball and socket joints (multiaxial movement)

Answer 18

shoulder joints and hip joints
