The adipose tissue is made up of adipose cells or adipocytes.
An adipose cell consists of fat globule which displaces the nucleus and cytoplasm to the periphery.
Adipose tissue is of two types i.e. white fat and brown fat.
White fat: These are larger cells with single large fat globule.
Brown fat: These cells contain a number of fat globules and they are brown in colour due to the presence of pigment cytochrome. This fat is found in hibernating mammals and newborn babies.
Location:
It is found in subcutaneous tissue, around the heart, kidneys, eyeballs, mesenteries and omenta, where fat storage is seen.
It is also present in the blubber of whales and elephants, the hump of a camel, fat bodies of frog etc.
Functions:
This tissue is chiefly a fat reserve.
Subcutaneous fat prevents heat loss from the body.
It forms a shock-absorbing cushion around the eyeballs and kidney.
Adipose tissue also provide support and protection.
