Large flat bones that usually protect vital organs e,g, cranium , ribs

Question 4

Define irregular bones

Answer 4

Specifically shaped bones designed to protect parts of the body e.g. virtibrae

Question 5

Answer 5

1. Movement
2. Mineral storage
3. Protection
4. Production of red blood cells
5. support
6. Shape

Question 6

How is movement created

Answer 6

When muscles contract they put on tendons which are attached to bones. this create movement

Question 7

Define joint

Answer 7

Place where 2 or more bones meet

Question 8

Define synovial joint

Answer 8

Its The most common type of joint which are specifically designed to allow movement and prevent injury

Question 9

What is synovial fluid used for

Answer 9

It lubricates the joint to reduce friction when moving

Question 10

Define bursae

Answer 10

Fluid filled bag that reduces friction

Question 11

Define synovial membrane

Answer 11

Lining of the joint that produces synovial fluid

Question 12

What is cartilage used for

Answer 12

It protects the end of bones and absorbs shock which therefore reduces friction

Question 13

What are ligaments used for

Answer 13

Ligaments attach bone to bone to help stabilise joints

Question 14

What do tendons attach too

Answer 14

Tendons attach muscle to bone

Question 15

Define hinge joints

Answer 15

Joints that allow body parts to achieve flexion and extension e.g. knee ankle elbow

Question 16

Define ball and socket joints

Answer 16

Joints that allow flexion, extension, adduction, abduction, circumduction and rotation e,g. Shoulder and hip

Question 17

Define plantar flexion

Answer 17

Pointing toes down

Question 18

Define dorsiflexion

Answer 18

Pulling toes up

Question 19

Define abduction

Answer 19

Moving away from midline of body

Question 20

Define adduction

Answer 20

Movement towards mid-line of body

Question 21

Define flexion

Answer 21

Angle joint decreases

Question 22

Define extension

Answer 22

Angle joint increases

Question 23

Define circumduction

Answer 23

Circular movement around the joint

Question 24
