Question 10

example of a saddle joint

Answer 10

radio-ulnur joint
atlas & axis in vertebrae

Question 11

parts of a joint

Answer 11

articulating cartilage
ligament
joint capsule
synovial fluid

Question 12

structure of articulating cartilage

Answer 12

glassy-smooth cartilage that is fairly spongy, which covers the end of the bones at a joint

Question 13

function of articulating cartilage

Answer 13

prevention of friction between yhe articulating surface, absorbes compression placed on the joint

Question 14

structure of ligaments

Answer 14

tough, fibrous connective tissue

Question 15

function of the ligament

Answer 15

connects one bone to another bone

Question 16

structure of a joint capsule

Answer 16

the outer layer is a tough fibrous layer called the fibrous capsule
inner layer= synovial memebrane

Question 17

function of a joint capsule

Answer 17

strengthens the joint so that the bones are not pulled apart.
secretes synovial fluid

Question 18

structure of a synovial fluid

Answer 18

protein rich fluid released from synovial membrane

Question 19

function of synovial fluid

Answer 19

reduces friction
nourish articulating cartilage
connects one bone to another

Question 20

types of joint movement

Answer 20

flexion
extension
pronation
rotation
abduction
Dorsi flexion
supernatant
plantar flexion
adduction
horizontal adduction
horizontal abduction
circumduction

Question 21

flexion

Answer 21

a decrease in joint angle, bending the joint

Question 22

extension

Answer 22

an increasing in joint angle, straightening the joint

Question 23

pronantion

Answer 23

Turing the palm of the hand down

Question 24

rotation

Answer 24

movement around the long axis of the body

Question 25

abduction

Answer 25

movement around the body's midline

Question 26

Dorsi flexion

Answer 26

bring the toes up towards the tibia

Question 27

supernation

Answer 27

turning the palm of the hand up s=holding a bowl of soup

Question 28

plantar flexion

Answer 28

pointing the toes downwards p=planting
