Exam 3 : Adipose Tissue: Anatomy & Development

Question 1

Where can Adipose tissue be found?

Answer 1

1. In the Visceral (Hidden fat)
2. Perinephric or pericardial (V)
3. Omental or Mesenteric (V)
4. Subcutaneous
5. Intermuscular
6. Intramuscular

V stand for the visceral fat

Question 2

Where can one found Perinephric or pericardial fat?

Answer 2

1. Arround the kidneys
2. Pelvis
3. Heart

Question 3

Where can Omental or mesenteric fat be found?

Answer 3

Found surrounding gastrointenstinal tract

Question 4

Where can subcutaneous fat be found?
Where can Intermuscular be found?
Where can intramuscular be found?

Answer 4

1. External fat under skin
2. Fat between muscles
3. Fat within muscle (marbling)

Question 5

What are the characteristics of White adipose tissue?

Answer 5

1. Predominant fat in the body
2. Long term energy storage
3. Less vascularity
4. Few cytoplasmic inclusions
5. Poorly developed mitochondria
6. After Lipolysis, fatty acids released from cell unlike brown adipose where fatty acids turned into heat inside cell.

Question 6

What are characteristics of Brown adipose tissue?

Answer 6

1. Extensive vascularity
2. High #’s of iron containing mitochondria, hence brown color
3. Common in neonates, hibernating animals, cold adapted animals

Question 7

What is non-shivering thermogenesis?

Answer 7

1. Increase in metabolic heat production
2. Not associated with muscle activity
3. Conducted by brown fat
4. Fatty acids converted to HEAT in adipose tissue due to uncoupling protein 1, allows uncoupling of oxidation from ATP formation

Question 8

When it comes to WAT and BAT what are their differences?

Answer 8

1. WAT is white, BAT is brown
2. WAT has a few vascularization, BAT has more sympathetic vascularization
3. WAT has less active metabolic activity, BAT has a high active metabolic activity
4. WAT has less sympathetic innervation, BAT has more sympathetic innervation
