BONE TISSUE AND MICROSCOPICAL STRUCTURE

Question 1

Bone tissue composition

Answer 1

Connective tissue: supports and protects tissue or organs, maintains form

Question 2

What are the two extracellular components

Answer 2

Organic and inorganic

Question 3

Explain organic extracellular components

Answer 3

33% of bone weight or composition, collagen fibre + other ground components/ substances
Function: resist tension

Question 4

Explain inorganic extracellular components

Answer 4

67%, hydroxypetite+ other ca minerals, Ca minerals ensures that the bone resists tension and compression

Question 5

The cellular component of the bone and four different types of it

Answer 5

2%, 4 different types are osteogenic, osteoblasts, osteocytes and osteoclasts

Question 6

Functions of extracellular components( HINT: 2% of bone weight or composition)

Answer 6

Osteogenic: stem cells, produce new osteoblasts
Osteoblasts: produce new bone matrix ( Makers)
Osteocytes: recycle protein or nutrients in bone matrix( maintainers)
Osteoclasts: remove bone matrix( destroyers)

Question 7

Gross structure of bones and their structure

Answer 7

Compact and cancellous, both of them are made up of same substances but different structure
Compact: osteon structure
Cancellous: trabecular structure

Question 8

Compact bone ( microscopically and microscopically)

Answer 8

Macroscopically: dense rough structure and immpenetrable
Microscopically: composed of circumfrential lumallae
