Flashcards in Chapter 5: Osseus Tissue Deck (28):
1

name the two ways bones are classified

shape or type

2

name the five types of bone shapes

long, short, flat, irregular, sesamoid

3

examples of long bones

humerus, ulna, femur, tibia, fingers and toe bones

4

define long bones

greater in length than width

5

define short bones

almost equal length and width

6

exmaples of short bones

carpal bones and tarsal bones

7

define flat bones

thin, large surface areas for attachment

8

example of flat bones

skull, scapula, sternum, ribs

9

define irregular bones

complex shapes, all other shapes

10

irregular bone examples

vertebrae, calcaneous, coxal

11

define sesamoid bones

develop in tendons where friction occurs, number can vary

12

examples of where sesamoid bones can be found

patella, feet

13

define diaphysis

shaft of bone, thin and in the middle made of compressed compact bone (will sometimes have spongy bone)

14

define epiphysis

proximal and distal ends of the bone; made of spongy bone

15

define medullary cavity

cavity within diaphysis where marrow is located

16

this type of marrow is made in adule and made of this type of tissue

yellow marrow, made mostly of adipose tissue

17

this type of marrow is made in children and has a specific function to...

red marrow, makes new blood cells

18

define metaphysis

region between diaphysis and epiphysis

19

why can yellow marrow turn back to red?

when there is extreme blood loss or are at high altitudes, yellow converts to red to produce blood cells

20

define periosteum

the outer covering of the bone (except articular surfaces). It adheres with collagen fibers

21

define endosteum

lining of the medullary cavity

22

define articular cartilage

hyaline cartilage made to reduce friction

23

where is articular carilage found

articulating surfaces of long bones, at the end of the epipysis

24

define epipyseal plate

"growth plate," the line of hyaline between the diaphysis and epiphysis within the metaphosis

25

define Endochondral Ossification

cartilage replaced by bone tissue, the process of bones growing in length

26

what type of tissue is osseous tissue

connective

27

what is the extracellular matrix of osseous tissue made of

calcium phosphate and calcium hydroxide which make hydroxyapatite crystal and collagen fibers

28

what are the different cells of the osseous tissue

osteoprogenitor cells, osteoblast, osteocytes, and osteoclast
