• pancreas
  • The pancreas is composed of two sections: the smaller endocrine portion, which is responsible for producing hormones such as insulin, somatostatin, and glucagon, and the larger, exocrine portion, which produces enzymes needed for the digestion of food. (wikipedia.org)
  • The damage can also extend into the endocrine portion of the pancreas, resulting in diabetes mellitus. (wikipedia.org)
  • Whether the diabetes is transient (temporary) or permanent depends on the severity of the damage to the endocrine pancreas beta cells. (wikipedia.org)
  • molecules
  • As opposed to endocrine factors that travel considerably longer distances via the circulatory system, other signaling molecules, such as paracrine factors involved in paracrine signalling diffuse over a relatively short distance. (wikipedia.org)
  • The movement of macromolecules and ligand molecules into the cell enables a complex transport system of intracellular signal transfers through different cellular environments until response is enabled. (wikipedia.org)
  • cells
  • The regulation of body functions by the endocrine system depends on the existence of specific receptor cells in target organs that respond in specialized ways to the minute quantities of the hormonal messengers. (infoplease.com)
  • The endocrine cells have dispersed throughout the body within 10 weeks. (wikipedia.org)
  • humans
  • A similar, but not identical, endocrine system to that of humans is found in nearly all vertebrates including other mammals, fish, amphibians, reptiles and birds, although the precise structures and roles of the various organs and hormones differ between different groups, particularly in relation to the different life cycle and development stages in different species. (europa.eu)
  • receptors
  • Second messengers may also be sent to interact with intracellular receptors in order to enter the complex signal transport system that eventually changes cellular function. (wikipedia.org)
  • functions
  • Invertebrates such as molluscs, crustacea and insects also have endocrine systems that control a similar range of body functions although these have evolved along markedly different lines to those of vertebrates. (europa.eu)
  • dominant
  • In a linear ranking system (often referred to as a pecking order), every member of the gender is recognized as either dominant or submissive relative to every other member, creating a linear distribution of rank. (wikipedia.org)
  • In a despotic system, one member is considered dominant while all other members of the living group are equally submissive. (wikipedia.org)
  • found
  • Examples of despotic social systems are found in meerkat, gray wolf, gorilla, Neolamprologus pulcher, and African wild dog. (wikipedia.org)
