1

5 function of bones?

-form framework to support movement
-protects vital organs
-attach to muscles to provide movement
-help produce red & white blood cells
-store calcium supply in body

2

8 bones that form cranium

(1) frontal , (2) parietal , (2) temporal , (1) ethmoid, (1) occipital, (1) sphenoid

3

frontal bone (cranium)

forms forehead, orbital roof, anterior cranial floor

4

parietal bone (cranium)

roof / upper side of cranium

5

temporal bone (cranium)

forms side and base of cranium

6

ethmoid bone (cranium)

part of orbit floor of cranium

7

occipital bone (cranium)

forms the back/ base of cranium

8

sphenoid bone (cranium)

forms anterior base of skull and part of wall of orbit

9

26 vertebrae?

protect spinal cord and support head/trunk of body

10

what are the 26 vertebrates?

7 cervical (neck) , 12 thoracic (chest) , 5 lumbar (lower back), 1 sacrum (back/ pelvic girdle) , 1 coccyx (tail bone)

11

true ribs?

first 7 ribs, attached to sternum (breastbone)

12

false ribs?

next 3 ribs, attached to the cartilage of rib

13

floating ribs?

last 2 ribs, no attachment to the front of the body

14

small piece of cartilage attached to the sternum?

xiphoid process

15

three regions on each os coxae?

Illium, ischium, and pubis.

16

3 types of joints

diarthrosis, amphiarthrosis, synarthrosis

17

diarthrosis degree of movement? example?

-freely movable
- ball socket on shoulder

18

amphiarthrosis degree of movement? example?

-slightly movable
-attachment of rib to thoraci

19

synarthrosis degree of movement? example?

-immovable
-cranium

20

purpose of ligaments?

tissue that connects bone to bone.

21

arthritis?

inflammation of joints

22

fracture?

crack or break in bone

23

osteomyelitis?

bone inflammation

24

osteoporosis?

bones become brittle/ fragile from loss of tissue

25

sprain?

twisting actions tears ligaments of joints

26

bursitis?

inflammation of a bursae

27

dislocation?

bone forcibly displaces from joint

28

scoliosis?

abnormal lateral curvature of the spine

29

what body parts are the long bones?

bones in legs and arms

30

what do the long bones do? why important?

-provide support and strength
- important because red and yellow marrow

31

wheres red marrow found? what dose it do?

-found in proximal end of humerus (arm) and femur (leg) as well as vertebrae, ribs, cranium and sternum.
-makes RBC's, platelets and some WBC's

32

whats blood made up of?

48% RBC's, 2% WBC's, 50% plasma

33

yellow marrow?

fat cells

34

whats the skull used for? made up of?

-provides protection for are brain
- its made up of cranial bones and facial bones

35

how many bones make up the skull?

eight bones

36

sutures

area where cranial bones join together

37

whats the vertebral spinal column?

26 bones that make up the vertebral column, they protect the spinal cord and support the head and trunk of body

38

what are pads between vertebrates do?

act as disks as shock absorbers, allows you to twist and bend

39

joints?

area where two bones attach for purpose of motion in the body

40

greenstick fracture?

when the bone is bent, mostly in kids

41

comminuted fracture?

when bones shattered into a bunch of pieces

42

impacted fracture?

the ends of bone are driven into each other

43

pathologic fracture?

caused by disease that weekends the bones

44

grout?

type of arthritis that forms when too much uric acid builds up in the body, joints inflame and swell up alot

45

bursitis?

inflammation of a small fluid sac that's surrounding the joint.

46

ruptured disk

when disk slips out of place and puts pressure on the spinal cord
