Connective tissue

Question 1

What are the connective tissues function?

Answer 1

• These bind, support and strengthens other body tissues
• Their a big transport system (blood is a connective tissue)
• A big site of stored energy reserves(Fat and adipose tissue is a connective tissue)
• If you can see your connective tissue, something is very wrong and you’re likely badly injured as it’s not found on the body surface (unlike epithelia) and it can be highly vascular. However LIKE epithelia it has a lot of nerves (excluding cartilage)

Question 2

Equation for connective tissue

Answer 2

CT = ECM + C

Question 3

Equation for extracellular matrix

Answer 3

ECM = GS + Fibres

Question 4

Equation for ground substance

Answer 4

GS = H20 + proteins + polysaccharides

Question 5

What are GAGS?

Answer 5

Glycosaminoglycans or mucopolysaccharides, they are negatively charged polysaccharide compounds

Question 6

Name the three kinds of protein fibres

Answer 6

• Collagen fibres
• Reticular fibres
• Elastic fibres

Question 7

Describe collagen fibres

Answer 7

Strong and flexible, is the most abundant protein and is common in bones, cartilages, tendons e.t.c

Question 8

Describe reticular fibres

Answer 8

Composed of collagen with coating glycoprotein, is made by fibroblasts and forms part of the basement membrane

Question 9

Describe elastic fibres

Answer 9

Thinner than collagen fibres, very stretchy as name suggest, found in skin, blood vessels and lungs

Question 10

What are the two common types of connective tissue and a brief description?

Answer 10

• Fibroblasts - Widely distributed in connective tissues, the secrete components of the matrix (Fibres and GS)
• Adipocytes - Fat cells, under skin and around organs and they store fat (triglycerides)

Question 11

Connective tissues can be either…

Answer 11

Embryonic or mature
