Adipose Tissue Flashcards
It is a special type of connective tissue dominated by fat cells (adipocytes) and plays an important role in thermoregulation (insulation) and energy metabolism.
Adipose tissue
Important role of adipose tissue
thermoregulation (insulation) and energy metabolism
It comprises about 20-25% of total body weight in healthy individuals, the main function of adipose tissue is to store energy in the form of lipids (fat).
Adipose tissue
Adipose tissue is comprises about how many percent of total body weight in healthy individuals?
20-25%
What is the main function of adipose tissue?
To store energy in the form of lipids (fat).
It is considered as one of the largest endocrine glands in the body as well as an active tissue for cellular reactions and metabolic homeostasis rather than an inert tissue for energy storage.
Adipose tissue
It is dysfunctionality is clearly associated to the onset of important pathologies including obesity, type 2 diabetes, dyslipidemia or nonalcoholic fatty liver.
Adipose tissue
Important pathologies of AT includes:
obesity, type 2 diabetes, dyslipidemia or nonalcoholic fatty liver
Adipose tissue is composed of a ________.
homogenous cell population
Adipose tissue may exist in association with all loose collagenous tissue, predeliction sites which may form an extensive subcutaneous sheet called ______.
panniculus adiposus
This tissue is a readily available source of energy.
Adipose tissue
This is an important contributor to thermoregulation, its somatic distribution aids in heat conservation.
Adipose tissue
This is also an important mechanical insulator through its distribution with the visceral organs and greater omentum.
Adipose tissue
What is the function of the adipose tissue of the synovial membranes.
absorbs shock and stabilizes joints.
two types of adipose tissues:
a. White adipose tissue
b. Brown adipse tissue
It is also called as white fat, unilocular fat and ordinary adipose fat.
White adipose tissue
White adipose tissue is also called as _______
white fat
Its cells are very large, they are spherical and may appear polyhedral. Unilocular fat cells, the predominant cells of this tissue have a signet-ring appearance.
White Adipose tissue
The bulk of the cytoplasm is occupied by the _________ is all that remains, the lipid solvents used in the process dissolve the fats
lipids
The lipids of these fats cells are ________ and certain fatty acids, which are mobilized through enzymatic hydrolysis by lipases. Free fatty acids then enter the blood as an available source of energy.
triglycerides
This tissue has multilocular fat cells. The predominant feature of these cells is the presence of many small fat droplets within the cytoplasm. The round nucleus is not displaced to one side of the cell but may assume many position.
Brown Adipose Tissue
The brown color of this tissue results from many mitochondria and high quantities of the cytochrome oxidase system.
Brown adioose tissue.
It contain more mitochondria, and the tissue is better vascularized and innervated than white fat cells.
Brown fat cells
Metabolism of the stored lipids releases ……
heat
warms the blood
raises the body temperature
It develops during the prenatal period and is confined generally to the axilla, interscapular region, mediastinum, mesenteries, and perirenal renal region.
Brown adipose tissue
The tissue may help young animals to resist postnatal extremes cold temperatures.
Brown adipose tissue
Hibernating rodents have these deposits in specific regions. These depots help maintain body temperature during hibernation.
