The Skeletal System

Question 1

What does the skeleton provide the body with ?

Answer 1

Attachment for the muscular systems movement

Protection for the vital organs

Question 2

How are bones formed ?

Answer 2

Through a process called ossification

Question 3

How many bones are in the human body ?

Answer 3

206 bones

Question 4

What is ossification ?

Answer 4

This is also known as bone remodelling. It is the process of laying down new bone material by cells called osteoblasts

Question 5

What is the Skeleton divided into ?

Answer 5

Axial skeleton

Appendicular skeletons

Question 6

What is cartilage ?

Answer 6

This is a tough, flexible connective tissue that covers the ends of bones at joints.

Question 7

What does cartilage provide ?

Answer 7

Provides cushioning to reduce friction and absorb shock during movement.

This supports structures such as the nose, ears and trachea

Question 8

What cartilage is found at the end of the bone ?

Answer 8

Hyaline cartilage

Question 9

What is meant by articulation ?

Answer 9

Where bones meet at the joints

Question 10

Does cartilage have its own blood supply ?

Answer 10

No it doesn’t

This means regenerating or regrowing cartilage takes a substantial period of time.

Question 11

What bones articulate at the hip joint ?

Answer 11

The pelvis and femur

Question 12

What bones articulate at the knee joint

Answer 12

Femur and tibia

Question 13

What bones articulate at the shoulder joint ?

Answer 13

Scapula and humerus

Question 14

What bones articulate at the elbow joint ?

Answer 14

Humerus, radius and ulna

Question 15

What bones articulate at the ankle joint ?

Answer 15

Tibia, fibula and talus

Question 16

What bones articulate at the wrist joint ?

Answer 16

Carpals and radius

Question 17

How many types of bones are there ?

Answer 17

5

Question 18

What are the 5 types of bones ?

Answer 18

Flat

Long

Short

Irregular

Sesamoid

Question 19

Give an example for each type of Bone

Answer 19

Flat- scapula

Long- femur

Short- talus, carpals

Irregular- vertebrae

Sesamoid- patella

Question 20

What is the function of the long bones ?

Answer 20

Provide leverage for movement and acts as a site for red and white blood cell production

Question 21

What is the function of short bones ?

Answer 21

Provide stability, support and allows for some movement

Question 22

What is the function of flat bones ?

Answer 22

Protect vital organs and provide a large surface area for muscle attachment

Question 23

What is the function of irregular bones ?

Answer 23

Provide protection and support and allows for muscle attachment

Question 24

What is the function of Sesamoid bones ?

Answer 24

Acts of leverage for movement, reduces friction and protects tendons from over stress

Overall leverage and protection

Question 25

What is the function of the axial skeleton

Answer 25

Protection, ensuring posture and red blood cell production

Question 26

What is the functions of appendicular skeleton

Answer 26

Allows for movement and muscle attachment

Question 27

What bones are part of the axial skeleton ?

Answer 27

These bones form the central core of the body: Skull- Cranium, mandible Vertebral column- cervical, thoracic, lumbar, sacrum, coccyx and ilium Ribcage and sternum

Question 28

What bones are found in the appendicular skeleton ?

Answer 28

Consist of bones used for movement and limb attachment Upper limbs e.g clavicle, radius and carpals Lower limbs e.g femur, patella and tarsals

Question 29

How many sections to the vertebrae are there ?

Answer 29

5

Question 30

Name all 5 sections of the vertebrae and how many vertebrae they have

Answer 30

Cervical- 7 Thoracic- 12 Lumbar-5 Sacrum-5 fused Coccyx- 4 fused

Question 31

How much of the body’s height is made up of the vertebral column ?

Answer 31

2/5

Question 32

How many bones in the vertebrae column ?

Answer 32

33
