skeletal system

Question 1

what are the 6 functions of the skeletal system

Answer 1

protection, shape, blood production, calcium storage, support, movement

Question 2

what are the components of the skeletal system

Answer 2

bone, ligaments, tendons, cartilage

Question 3

what do the ligaments connect

Answer 3

bone to bone

Question 4

what do the tendons connect

Answer 4

muscle to bone

Question 5

where is the cartilage found

Answer 5

joints & growing bones

Question 6

what are the functions of the cartilage

Answer 6

1. reduces friction
2. firm and flexible (cushion effect)

Question 7

function of yellow bone marrow

Answer 7

stores fat

Question 8

function of red bone marrow

Answer 8

responsible for producing blood cells (hematopoiesis)

Question 9

state the 5 bone shapes

Answer 9

1. flat bones
2. long bones
3. sesamoid bones
4. irregular bones
5. short bones

Question 10

describe flat bones and give examples on where they may be found

Answer 10

• relatively thin, flattened shape
• eg. bones of the skull and sternum

Question 11

describe long bones and give examples on where they may be found

Answer 11

• longer than they are wide
• eg. upper and lower limb bones

Question 12

describe sesamoid bones and give examples on where they may be found

Answer 12

• small and round, are found embedded in tendons
• eg. patella

Question 13

describe irregular bones and give examples on where they may be found

Answer 13

• have shapes that do not fit readily into the other three categories
• eg. vertebrae and facial bones

Question 14

describe short bones and give examples on where they may be found

Answer 14

• bones that are more or less equal in length, width and thickness
• eg. the bones of the wrist and ankle

Question 15

components of a long bone

Question 16

function of the endosteum and where is it found

Question 17

what is the epiphyseal plate and where is it found

Question 18

what is the medullary cavity and where is it found

Question 19

what is the nutrient foramen and where is it found

Question 20

what is an osteon

Question 21

composition of the compact bone

Question 22

proportion of the compact bone

Question 23

3 functions of the compact bone

Question 24

structure of the compact bone (4)

Answer 24

Lamellar: Mature compact bone islayeredor lamellar in structure.
Haversian Systems: An intricate network ofinterconnecting vascular canalscalledhaversian systemspermeates compact bone. These canals supply blood to osteocytes.
Osteons: The bone is organized into concentric layers around haversian canals, forming structural units known asosteons.
Immature Compact Bone: Initially, compact bone lacks osteons and exhibits awoven structure (less organized). Over time, it transforms into mature bone through a process of remodeling.
