This deck contains questions on
- function of connective tissue
- types of connective tissue

Answer 1

Enjoy :)

Question 2

State the 4 major functions of connective tissue

Answer 2

Mechanical, Metabolic, Defence & Repair, Growth & Morphogenesis

Question 3

Elaborate on Mechanical Function of Connective Tissue

Answer 3

• Supporting matrix
• Transmission of forces
• Facilitation of movement

Question 4

Elaborate on Metabolic Function of Connective Tissue

Answer 4

Route for exchange between blood and other tissues

Fat storage

Question 5

Elaborate on Defence & Repair Function of Connective Tissue

Answer 5

Insulation, cushioning/padding

Injury, infection and repair

Question 6

Elaborate on Growth & Morphogenesis Function of Connective Tissue

Answer 6

Growth and morphogenesis:

Control cellular behaviour

Proliferation for growth

Growth factor gradients

Question 7

Connective tissue is comprised of …………………………………………………………………………………………………………………………………………………….

Answer 7

cells, fibres and macromolecules which act as the ‘ground substance’ for the ECM
- cells, gels and fibres

Question 8

Name the different types of connective tissues

Answer 8

Embryonic CT = mesenchyme, mucoid
Specialised CT = bone. cartilage, blood
CT proper = Loose CT & Dense CT
Loose CT = areolar tissue, adipose tissue & reticular CT
Dense CT = Dense Regular CT and Dense Irregular CT

Question 9

So CT proper is further split into loose CT and Dense CT
Dense CT = further split into dense regular CT & dense irregular CT
- Elaborate on DENSE CT, DENSE REGULAR CT & DENSE IRREGULAR CT

Answer 9

Dense connective tissue

For resistance and protection

Contains fewer cells than loose connective tissue, and more collagen fibres

Less flexible but more resistant to stress

Dense regular connective tissue (tendons)

Collagen fibres aligned with linear orientation of fibroblasts along lines of prolonged stress in 1 direction

For example, tendons attaching striated muscle to bone
Dense irregular connective tissue (dermis)

Collagen fibres in bundles with no predominant orientation

3D network forms resistance to stress in all directions, e.g. in dermis of the skin- used to anchor the epithelium

Question 10

Details about adipose tissue

Answer 10

Adipose (fat) tissue

White adipose

Mature adipocytes have a single large droplet of triglyceride fat, very little cytoplasm (immature cells have smaller lipid droplets)

For energy storage, insulation, padding

Brown adipose

More cytoplasm and many mitochondria, multiple small lipid droplets

For sympathetic innervation/ heat generation- mitochondria are for heat generation

Question 11

elaborate about elastic tissue

Answer 11

confirm …
Elastic tissue

Bundles of thick, parallel elastic fibres

These are fibres of elastin associated with a glycoprotein

Found in blood vessels (e.g., aorta)
