The extra cellular matrix+bones

Question 1

function of ECM

Answer 1

provides structure and support of the body

Question 1

fibroblast

Answer 1

loose connective tissue -surrounding glands and blood vessels

Question 2

structure of fibroblast

Answer 2

collagen-is thick and elastin-is thin and mixing it together from the matrix

Question 3

chondrocyte- cartilage

Answer 3

tissue constructed of matrix -surround by cartilage cells

Question 4

cartilage cells

Answer 4

more dense and flexible than bone

Question 5

osteocyte

Answer 5

bone

Question 6

ECM 1st part

Answer 6

fibrous proteins:collagen and elastin -strength and flexibility

Question 7

ECM 2nd part

Answer 7

hydrated gel-like matrix: protein polycharrid, which are called proteogylacans-glycoprotiens with glycosaminglygen linkages

Question 8

collagen

Answer 8

rigid-contains collagen which are close together

Question 9

elastin

Answer 9

multiple polypeptide

Question 10

bones

Answer 10

structure support and attachment sites for body -helps store minerals

Question 11

osteogenesis

Answer 11

formation of bone-secretes matrix

Question 12

hydroxyapitate

Answer 12

calcium +phosphate crystals -are in collagen fibres made by osteocytes

Question 13

2 types of bone

Answer 13

1.cortical:compact -strong and dense
2.cancellous:spongy -network of trabecula less dense compared to cortical

Question 14

osteocytes

Answer 14

small chambers called lacunae and are linked by canaliculi and form rings called lamellae around haverian canal which houses blood vessels

Question 15

what makes up the bone

Answer 15

osetoclasts and osteoblasts

Question 16

where do osteoclasts come from

Answer 16

hematopoietic stem cells

Question 17

synarthroses

Answer 17

immovable joints

Question 18

amphiarthroses

Answer 18

slightly moveable joint

Question 19

diathroses

Answer 19

freely moveable

Question 20

fibrous joints

Answer 20

immovable

Question 21

cartilaginous joints

Answer 21

immoveable, slightly immovable

Question 22

synovial joints

Answer 22

freely moveable

Question 23

elastic cartilage

Answer 23

contains flexible type 3 collagen fibres and elastin

Question 24

what does mesenchymal stem cells differentiate to

Answer 24

chondroblast which make different chondrocytes
