fat body

n.1. A food reserve of fatty tissue in the larval stages of certain insects.2. A mass of fatty tissue located near the genital glands in some amphibians, including the frogs and toads.

n 1. (Zoology) a mass of fatty tissue in insects, used as an energy source during hibernation and metamorphosis 2. (Zoology) a similar tissue mass in amphibians and reptiles

Fat Body

fat body

[′fat ‚bäd·ē] (invertebrate zoology) A nutritional reservoir of fatty tissue surrounding the viscera or forming a layer beneath the integument in the immature larval stages of many insects. (vertebrate zoology) A mass of adipose tissue attached to each genital gland in amphibians.

Fat Body

(1) Areolar tissue in the body of insects and some other arthropods that fills the spaces between the internal organs and underlying walls of the body. The cells of the fat body are rich in fat (hence the name). It is filled with tracheae and may be white, orange, yellow, or green. The cells of the fat body are the site where nutrients (fats, proteins, and carbohydrates) accumulate and where metabolic products (uric acid salts and so forth) accumulate and are excreted. In larvae, the fat body consists of external (parietal) and internal (visceral) lobes. This division is indistinct in adult insects.

In some luminescing insects, the fat body or a separate organ contains a luminescing substance called luciferin. In many insects, the fat body contains the so-called mycetomes—symbiontic microorganisms (bacteria, fungi) that participate in metabolism and are found in certain parts of the fat body.

(2) In amphibians, the fat body is a yellow irregularly shaped structure located above each testis that nourishes the testis and the spermatozoa developing in it.

fat body

fat-pad

(fat'pad), [TA] An accumulation of somewhat encapsulated adipose tissue. Synonym(s): corpus adiposum [TA], fat body ☆

fat body

(in amphibians and lizards) a structure in the form of finger-like growths immediately in front of the gonads. The fat body stores fat as ADIPOSE TISSUE and is largest just before hibernation. It is of special importance in males where little or no food is taken in the breeding season, after which it is greatly reduced in size.
(in insects) a loose network of tissue in spaces between organs and around the gut, storing fat, proteins, glycogen and uric acid. It is found especially in juvenile insects before METAMORPHOSIS.
