Cell injury/ Degeneration 1

Question 1

What is morphology?

example: penguins

Answer 1

Feathers - short, black and white
Wings - stumpy and flipper like
Body Shape - stumpy

Question 2

What is behaviour?

example: penguins

Answer 2

orientation - standing upright, grouped with others
location - Antarctica (to south america)
Indication of function - flying

Question 3

Explain the structure of epithelial cells, basement membrane and connective tissue in making skin?

Answer 3

epithelial cells are joined together with each other but are floppy so require a basement membrane (made of glycoproteins and collagen) to help the epithelial cells keep their shape. The connective tissue then connects muscles to bones, giving a more stable structure.

Question 4

What are functional cells (parenchyma)?

Answer 4

epithelial cells (skin, mucosa, glands)
endothelial cells (blood vessels)

*parenchymal cells of organs (e.g. liver & muscle cells, neurons –> essentail/ functional part of organs

Question 5

What are the connective tissue framework (stoma)?

Answer 5

• loose (dermis)
• dense (tendons and ligaments)
• reticular (organs such as liver, spleen, lymph nodes)
• collagen fibres (strength) - made by fibroblasts
• elastin fibres (stretch)

Question 6

What do mesenchymal cells produce?

Answer 6

fibroblasts, chondroblasts and osteoblasts
