Insects possess two fundamental types of cuticular exocrine glands: type 1 glands are unicellular, that is they are small glands made up of single (epidermal) cells, and type 2 glands which are larger multicellular organs. These glands may be found . FUN FACT: The skin is the largest organ of the human body! CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Communication in social insects to a very considerable extent is mediated by the action of chemical messenger molecules or pheromones. These are also called prothoracic glands or ecdysial glands. They are distinct from the other type of gland, endocrine, in that exocrine gland secretions end up external to the body, while endocrine secretions go into the bloodstream/internal.

Endocrine glands 1- Glands producing ecdysteroids In the immature stages of all insects, molting hormones are produced by the prothoracic glands. These glands are ubiquitous among insects, and are found on almost every region of the body in various taxa. The specialized attachment mechanism of the eggs of this species is elucidated and the first experimental approach to systematically characterize the functional properties of their adhesion by using different microscopy techniques and attachment force measurements on substrates with differing degrees of roughness and surface chemistry, as well as repetitive attachment/detachment cycles while under the influence of water contact. Histology of female sex pheromone gland. The key difference between the two types is that, whereas exocrine glands secrete substances into a ductal system to an epithelial surface, endocrine glands secrete products directly into the . Fisher and Robertson (Insect Soc 46: 78-83, 1999) discovered the production of silk-like secretions emerging from slit-shaped openings along the anterior margin of the ventral hypostoma of Melissotarsus ant workers. Exocrine glands are glands that secrete substances onto an epithelial surface by way of a duct.

Transmission electron microscopy has revealed that the elongated labium of rove beetles of the genus Stenus forms an adhesive capture apparatus that enables them to catch fast-fleeing prey such as Collembola. Exocrine gland secretions in insects are involved in reproductive and defensive behav-iour (Pasteels et al. Endocrine glands are the glands that secrete hormones without ducts, while exocrine glands secrete hormones through ducts.

Exocrine glands are composed of a glandular portion and a duct portion. from exocrine glands, which are anatomical structures often specialized for synthesis and secretion (Meer and Preston 2008). More recently, Cruz-López et al. Anatomically, these glands are broadly classified into two types based on the presence or absence of ducts. Abbreviations: C, cuticle; D, duct cells; G1, secretory cells class 1; G2, secretory cells class 2; G3, secretory cells class 3; S, campaniform sensilla (modified after Noirot and Quennedey, 1974). For exam-ple, terrestrial ants have wide glandular sources of recruitment pheromones (Dufour's gland, the pygidial glands, poison glands, sternal glands, hindgut and rectal glands). Compare and contrast endocrine and exocrine glands. This is a project of the International Union for the Study of Social Insects (IUSSI), the worldwide organizing body for the scientific study of social insects. These prothoracic glands manufacture ecdysteroids , a group of closely-related steroid hormones (including ecdysone) that stimulate synthesis of chitin and protein in epidermal cells and trigger a cascade of physiological events that . Melatonin regulates the body's sleep patterns in both circadian (daily) and seasonal patterns. At night, in the absence of light, the pineal gland secretes the hormone melatonin.

Insects represent the most abundant and diverse animal group on Earth. The number of described species is more than one million and up to ten million are estimated. It is hypothesize that the adhesive secretion is formed by two gland types (goblet and flask cells), and that the release of the sand coat may occur mechanically, i.e. To evaluate functional aspects of the glue–solvent interaction, the effects of a broad array of chemical solvents on the glue activation and measured corresponding adhesive forces were tested. • The skin consists of three layers: the epidermis, dermis, and subcutaneous Open and release their products outside called as "exocrine glands". Electron microscope radioautographs prepared from glands labeled with radioactive amino acids in culture have provided further evidence that the dense secretory granules are indeed composed, at least in part, of proteins synthesized de novo by the large gland cells. The present ultrastructural investigation using scanning and transmission electron microscopy as well as light and fluorescence microscopy describes in detail the attachment devices and tarsal gland of the bug Coreus marginatus (L.) (Hemiptera: Coreidae) and hypothesise a fluid emission mechanism based on changes of the hydraulic pressure inside the gland, due to the unguitractor tendon movements.
