Question 1

3 main functions of skeletal system (sat morning mumps - MPS)

Answer 1

movement, protection and storage of minerals and fats

Question 2

functions of bones (think milk)

Answer 2

synthesize blood and immune cells, store calcium phosphate and lipids

Question 3

4 major types of bones

Answer 3

long, short, flat, and irregular

Question 4

ex. of long bone

Answer 4

femur

Question 5

marrow in a long bone (long yellow)

Answer 5

yellow marrow that stores lipids

Question 6

found at the end of long bones

Answer 6

red marrow, site of blood cell production

Question 7

growth plates

Answer 7

at the ends of long bones, where bone lengthens if it’s growing

Question 8

ex of short bones

Answer 8

square bones of wrists and ankles

Question 9

ex of flat bones and their function

Answer 9

protect vital organs - ribs

Question 10

flat bones contain…

Answer 10

red bone marrow and produce blood cells

Question 11

ex. of irregular bones

Answer 11

hips and parts of skull

Question 12

ligaments (leg to leg - bone to bone)

Answer 12

attach bones to other bones

Question 13

only bone in body not connected to other bones

Answer 13

hyoid-held only by muscle

Question 14

hyaline cartilage

Answer 14

covers articulating surface of bones so they don’t grind together

Question 15

ex. of synovial joints (balling is a sin)

Answer 15

ball and socket, hinge - usually capable of movement. knee hinges, have synovial fluid

Question 16

bone is synthesized in…

Answer 16

tubular structure call osteons

Question 17

osteons composed of…(apatite)

Answer 17

calcium and phosphate rich hydroxyapatite embedded in collagen

Question 18

haversian systems

Answer 18

osteons

Question 19

osteocytes are in…(hide from cyte)

Answer 19

cave like spaces called lacunae

Question 20

matrix forms around the…

Answer 20

central canal that contains blood vessels and nerves

Question 21

2 main types of bone cells (many clasts and one blast)

Answer 21

multinucleate osteoclasts and mononucleate osteoblasts

Question 22

osteoblasts do what?

Answer 22

replace cartilage and secrete mineral deposits that form the matrix

Question 23

nonliving substance of the bone

Answer 23

the matrix

Question 24

osteoblasts develop into…

Answer 24

osteocytes, which strengthen bone tissue and perform metabolic functions

Question 25

osteoclasts do what?

Answer 25

break down bone minerals of the matrix

Question 26

if osteoclasts break down bone faster than osteoblasts deposit minerals...

Answer 26

bone becomes weak, causing osteoporosis

Question 27

excessive withdrawal of minerals from bone can cause...

Answer 27

bone to lose rigidity and lead to osteoporosis

Question 28

arthritis

Answer 28

damages cartilage between joints.

Question 29

brittle bone disease (brittle w/out...)

Answer 29

osteogenesis imperfecta - genetic defect in the collagen matrix. the genes that code for collagen in the matrix are missing, and bone breaks easily

Question 30

muscle connects to bones with..

Answer 30

tendons, which is connective tissue

Question 31

prime mover

Answer 31

the contracting muscle

Question 32

antagonist

Answer 32

the relaxed muscle in the pair

Question 33

serve as functional units of compact bone

Answer 33

osteon

Question 34

has a high number of mitochondria

Answer 34

skeletal muscle

Question 35

flat red...

Answer 35

long yellow
