tissues 2

Question 1

fluid connective tissie (bloo000dd)

Answer 1

matrix: plasma
-liquid and lacks fibers

Question 2

fluid connective tissue: Haemopoietic tissue

Answer 2

-forms blood cells
-found in bone marrow
-types of bone marrow -> red: surrounded by a framework of reticular fibres. produces red and white cless

yelllow - yeloow adipose tissue

Question 3

bone histology

Answer 3

Bone martix
->organic : collagen and proteoglycans
->inorganic: hydroxyapatite
-if mineral removed, bone –> bendable
-if collagen removed, bone —-> too brittle

Question 4

Bone cells (osteoblasts) create the martix

Answer 4

formation of bones through ossification

ossification is when osteoblasts communicate through gap junctions. cells surrond themselves by matrix

Question 5

osteocytes (stellate) maintain the matrix

Answer 5

mature bone cells. surrounded by martix but can make small amount of matrix to maintain it

Question 6

bone cells osteoclasts (break the matrix down for remodelling)

Answer 6

-resorption of bone

Question 7

woven and lamellar bone

Answer 7

woven bone - collagen fibres randomly formed
-during fetal development///during fracture repair

remodeling - removing old boen and adding new
-woven bone is remodeled into lamellar bone

lamellar bone - mature in sheets called lamellae.

Question 8

spongy bone

Answer 8

-trabeculae: interconnecting rods or plates of bone. like scaffolding.

Question 9

compact bone

Answer 9

-central canals: parallel to long axis
-osteon system: central canal, content, associated concentric lamellae and osteocytes
