Adipose Tissue

Question: What do you call a benign neoplasm arising from adipose tissue? What do you call a benign neoplasm arising from adipose tissue?

Answer: A fatty lipoma?

Question: What form of fat is carried in the blood by lipoproteins and is stored in the adipose tissue? What form of fat is carried in the blood by lipoproteins and is stored in the adipose tissue? amino acids, cellulose, triglycerides, or phospholipids

Answer: im pretty sure triglycerides. if glycogen is a triglyceride, then absolutely sure.

Question: Can you give me an example of homeostatic imbalance involving adipose tissue? I know that homeostatic imbalance is when the internal body's environment isn't changing to tolerate the body's external environment. I also know that adipose tissue contributes to the body's heat source. I just need help explaining it better.

Answer: In histology, adipose tissue or fat is loose connective tissue composed of adipocytes. Adipose tissue is derived from lipoblasts. Its main role is to store energy in the form of fat, although it also cushions and insulates the body. Obesity or being overweight in humans and most animals does not depend on body weight but on the amount of body fat—specifically, adipose tissue. Two types of adipose tissue exist: white adipose tissue (WAT) and brown adipose tissue (BAT). Adipose tissue also serves as an important endocrine organ[1] by producing hormones such as leptin, resistin and the cytokine TNFα . The formation of adipose tissue appears to be controlled by the adipose gene. [edit] Anatomical features In humans, adipose tissue is located beneath the skin, and is also found around internal organs. Adipose tissue is found in specific locations which are referred to as 'adipose depots'. Adipose tissue contains several cell types, with the highest percentage of cells being adipocytes, which contain fat droplets. Other cell types include fibroblasts, macrophages and endothelial cells. Adipose tissue contains many small blood vessels. In the integumentary system, which includes the skin, it accumulates in the deepest level, the subcutaneous layer, providing insulation from heat and cold. Around organs, it provides protective padding. However, its main function is to be a reserve of lipids, which can be burned to meet the energy needs of the body. Adipose depots in different parts of the body have different biochemical profiles. In a severely obese person, excess adipose tissue hanging downward from the abdomen is referred to as a panniculus (or pannus). A panniculus complicates surgery of the morbidly obese. The panniculus may remain as a literal "apron of skin" if a severely obese person quickly loses large amounts of fat (a common result of gastric bypass surgery). This condition cannot be effectively corrected through diet and exercise alone, as the panniculus consists of adipocytes and other supporting cell types shrunken to their minimum volume and diameter. Reconstructive surgery is one way to fix the problem. In mice, there are eight major adipose depots, four of which are within the abdominal cavity: the paired gonadal depots are attached to the uterus and ovaries in females and the epididymis and testes in males, the paired retroperitoneal depots are found along the dorsal wall of the abdomen, surrounding the kidney, and when massive extend into the pelvis. The mesenteric depot forms a glue-like web that supports the intestines, and the omental depot, which originates near the stomach and spleen and when massive extends into the ventral abdomen. Both the mesenteric and omental depots incorporate much lymphoid tissue as lymph nodes and milky spots respectively. The two superficial depots are the paired inguinal depots, which are found anterior to the upper segment of the hind limbs (underneath the skin) and the subscapular depots, paired medial mixtures of brown adipose tissue adjacent to regions of white adipose tissue, which are found under the skin between the dorsal crests of the scapulae. The layer of brown adipose tissue in this depot is often covered by a “frosting” of white adipose tissue, sometimes these two types of fat (brown and white) are hard to distinguish. The inguinal depots enclose the inguinal group of lymph nodes. Minor depots include the pericardial which surrounds the heart, and the paired popliteal depots, between the major muscles behind the knees, each containing one large lymph node(Pond 1998). Of all the depots in the mouse, the gonadal depots are the largest and the most easily dissected (Cinti, 1999), comprising about 30% of dissectible fat, e.g., (Bachmanov et al. 2001). [edit] Physiology This article needs additional citations for verification. Please help improve this article by adding reliable references. Unsourced material may be challenged and removed. (July 2007) Free fatty acid is "liberated" from lipoproteins by lipoprotein lipase (LPL) and enters the adipocyte, where it is reassembled into triglycerides by esterifying it onto glycerol. Human fat tissue contains about 87% lipids. In humans, lipolysis is controlled though the balanced control of lipolytic B-adrenergic receptors and a2A-andronergic receptor mediated antilipolysis. Fat is not laid down when there is a surplus available and stored passively until it is needed; rather it is constantly being stored in and released from each cell. Fat cells have an important physiological role in maintaining triglyceride and free fatty acid levels, as well as determining insulin resistance. Abdominal fat has a different metabolic profile—being more prone to induce insulin resistance. This explains to a large degree why central obesity is a marker of impaired glucose tolerance and is an independent risk factor for cardiovascular disease (even in the absence of diabetes mellitus and hypertension).[citation needed] Recent advances in biotechnology have allowed for the harvesting of adult stem cells from adipose tissue, allowing stimulation of tissue regrowth using a patient's own cells. The use of a patient's own cells reduces the chance of tissue rejection and avoids the ethical issues associated with the use of human embryonic stem cells. Adipose tissue is the greatest peripheral source of aromatase in both males and females contributing to the production of estradiol. Adipose derived hormones include: Adiponectin Resistin Angiotensin Plasminogen activator inhibitor-1 (PAI-1) TNFα IL-6 Leptin Estradiol (E2) Adipose tissues also secrete a type of cytokines (cell-to-cell signalling proteins) called adipokines (adipocytokines) which play a role in obesity-associated complications. [edit] Brown fat A specialised form of adipose tissue in human infants, and some hibernating animals, is brown fat or brown adipose tissue. It is located mainly around the neck and large blood vessels of the thorax. This specialised tissue can generate heat by "uncoupling" the respiratory chain of oxidative phosphorylation within mitochondria, leading to the breakdown of fatty acids. This thermogenic process may be vital in neonates exposed to the cold, who then require this thermogenesis to keep warm as they are unable to shiver, or take other actions to keep themselves warm.[2] Attempts to stimulate this process pharmacologically have so far been unsuccessful, but might in the future be a target of weight loss therapy. [edit] Genetics In 2007, researchers isolated the adipose gene, which ap­par­ently serves to keep animals lean dur­ing times of plen­ty. Increased adipose gene activity was associated with slimmer individuals.[3] [edit] Physical properties Adipose tissue has a density of ~0.9g/ml [4]. Thus, a person with much adipose tissue will float easier than a person with lot of muscular tissue, since muscular tissue has a density of 1.06 g/ml[4]. [edit] Cultural and social role Excess adipose tissue on a human can lead to medical problems; however, a round or large figure does not of itself imply a medical problem, and is sometimes not primarily caused by adipose tissue. For a discussion of the aesthetic and medical significance of body shape, see dieting and obesity. The term "adipose" was also used as the name of a character in a 2008 episode of the British science fiction series Doctor Who, Partners in Crime. Aliens called "the Adipose" are part of a plan involving diet pills, hence the link with fat tissue. Homeostastis is another term for homeostatic imbalance<<<3 just to let you kno!

Question: Is it correct to define, in a histological tissue, the presence of adipocytes as adipose tissue? or this definition (adipose tissue) is wrong when there are adipocytes ?

Answer: no as you may be describing fatty infiltration of another tissue, say liver. when you use the term 'adipose tissue' you are referring to a histological type of tissue, say from subcutaneous fat.

Question: How do you calculate the Surface Area to Volume Ratio of Adipose Tissue? How do you calculate the SA to Volume Ratio of adipose tissue? *get the measurements online* My teacher gave me this problem and I have no idea how to do it. Please help! *more so, how do you calculate the volume and corresponding SA of adipose tissue? >_> I'm not sure if adipose tissue is spherical, although I don't think it is x_X and I'm taking A.P. Biology in High School

Answer: dang, girl...what class are you taking????

Question: What form of fat is stored in the adipose tissue? What form of fat is carried in the blood by lipoproteins and is stored in the adipose tissue? a. amino acids b. cellulose c. triglycerides d. phospholipids Please support with fact/detial

Answer: c - triglycerides Amino acids are building blocks for proteins, not fats at all. Cellulose is an organic fibrous polymer synthesized by plants, not animals; also not a fat. And phospholipids are modified types of fat used in membrane formation. http://www.sportsci.org/encyc/adipose/ad…

Question: How is adipose tissue formed? how does a lipid molecule in the small intestine become adipose tissue? I know what adipose tissue is but what path does a lipid molecule take from a lacteal to adipose tissue?

Answer: Dietary triglycerides are broken down by lipase to fatty acids and monoglycerides which are absorbed into the surface intestinal cells. There they are reformed to triglycerides and packed into chylomicron particles which are spherical with their surface made of water soluble phospholipids and different kinds of protein while the inside is packed with the triglycerides and also cholesterol. It's the body's way to transport triglycerides which are not soluble in the water medium of blood plasma and lymph. Chylomicrons move into the lymph and then to the blood which eventually carries them to the adipose tissue. There the blood capillary walls extract the fatty acids through lipoprotein lipase and they are subsequently absorbed by adipose cells. The glycerol part is freed into the blood and goes to the liver. Only cholesterol remains in the chylomicrons and this is transported to the liver. In other words through chylomicrons fats are delivered to adipose tissue and cholesterol to the liver.

Question: Target cells in adipose tissue respond to insulin by increasing the # of GLUT 4 transporters in the membranes? Target cells in adipose tissue respond to insulin by increasing the number of GLUT 4 transporters in their membranes. A) True B) False

Answer: true

Question: Please only answer if you really know, How to activate brown fat (brown adipose tissue (BAT))? brown adipose tissue (BAT), is now known as an aid to burn fat healthily, as this fat burns calories, while white fat is inert and is bad for you.So when activated it starts to function making you slimmer, caffeine seems to do it but is not the best or healthy thing to do as may cause other problems taking it. So I am looking on other ways of doing it. So if you a doctor scientist and know better please help.

Answer: Yeah, brown fat is cutting edge stuff. I'm actually researching brown fat as part of a term paper on obesity for a nutrition and disease class in college. To answer your question, you can stimulate brown fat using certain hormones, eg. stress hormone and also a colder climate is supposed to stimulate activity of brown fat. It is thought that brown fat acts as a balance to white fat, where white fat is responsible for storing energy and brown fat is responsible for releasing energy. Check this out: http://www.pbs.org/newshour/bb/health/ja… There's also an article called 'Identification and Importance of Brown Adipose Tissue in Adult Humans' in the New England Journal of Medicine, which gives you a whole lot more. If you want e-mail me, and I'll e-mail you a pdf copy of the article.

Question: Any personal trainers that know how to how to get rid of adipose tissue? I've read this is used on bodybuilders and that celebrities use this trick. I'm curious how to get rid of it? Thanks in advance!

Answer: Getting rid of adipose tissue is just a fancy way of saying "trim the fat" Its not a secret, eat healthy, workout with both cardio and resistance training, and get enough sleep. Don't overeat

Question: What features of adipose tissue and blood are not typical connective tissue characteristics?

Answer: Adipose tissue and blood do not contain collagen and elastin fibers. Nor do they contain solid extracellular ground substance. Adipose tissue does not include an extracellular matrix of any kind.

Question: What are some disorders caused by adipose tissue? Please be specific.

Answer: The best answer is obesity:)

Question: what does adipocytes in adipose tissue serve as other than storage sites? these are my choices... produce linocleic fatty acid synthesize triglycerides increase glugagon release dengrade fat-soluable vitamins i think its synthesize triglycerides...can you please tell me if im right? thanks!

Answer: yes i think its synthesize triglycerides. Adipose can like store fat and adipocytes can synthesize this.

Question: What is another plant cell similar to the adipose tissue’s functions?

Answer: seed endosperm cells

Question: Why do we need to eat everyday even though we have energy stored in our adipose tissue? Explain at the scientific level.

Answer: eating isnt just about energy, its about taking nutrients that our bodies need to function properly

Question: What is the function of the adipose tissue around the eye?

Answer: It supports and cushions the eye within the socket.

Question: Cachexia is a condition in which so few calories are consumed that adipose tissue disappears.? List three possible causes for this condition. Identify the eating disorder related to it. thx!

Answer: 1. self starvation 2. inability to digest food the right way (no nutrients or calories are consumed from it). 3. celiac disease? that's when there is a gluten allergy and you lose so much weight and it's extremely hard to gain it back. you don't have enough protein or fat either cause it basically screws up your entire digestive system. I'm guessing the eating disorder would be anorexia because bulimia alone doesn't usually cause extreme weight loss although anorexia is usually linked to bulimic behaviors as well.

Question: can anyone describe how the structure of adipose tissue is related to its function,thanks? Iam doing biology course describing different tissues structure and how its relation to its funtion.

Answer: Well I don't know if this is specific enough, but I'll give it a shot. Adipose tissue is your fat tissue (made up of fat cells). It's purpose is to cushion and insulate our bodies.....hope this helped...?
