A

white adipose tissue

brown adipose tissue

18
Q

white adipose tissue is also called

A

uninocular adipose

19
Q

has signet ring appearance

A

white adipose tissue

20
Q

most common type, compose of cells that when completely developed, contains 1 very large droplet of witish yellow fat in their cytoplasm.

A

white adipose tissue

21
Q

brown adipose tissue also called

A

multilocular adipose

22
Q

contains cell with multiple lipid droplets interspersed among abundant mitochondria which gives a darker appearance

A

brown adipose tissue

23
Q

adipose tissue also came from

A

Mesenchymal cells

24
Q

can be fibroblast or free adipocytes

A

brown adipose tissue

25
functions of White adipose tissue`
-Specialize for long term energy storage
26
Why is white adipose tissue called unilocular?
Because triglycerides are stored in alarge dipid droplet
27
almost all adipose tissue in adults are
uninocular
28
benign tumors
lipoma
29
malignant adipose tumor
liposarcomas
30
fetal lipoma of brown fat
hybernoma
31
obesity is caused by
excessive formation of adipose tissue when energy intake exceeds energy expenditure
32
specialized form of AT.
Brown adipose tissue
33
brown adipose tissue constitute ____ of newly born body weight.
2-5%
34
location of brown adipose in baby
back, neck and shoulders
35
for heat production
Brown adipose tissue
36
heat production by
non shivering thermogenesis
37
cells are smaller than WAT and centrally located
Brown adipose tissue
38
adipocytes of brown fat are
closely packed with each large capillaries
39
heat production because
mitochondria in their inner membrane much greater level of a transmembrane protein called thermogenin/uncoupling protein 1
