Record 2 2021-10-25

English

Subject field(s)
  • Aquaculture
CONT

At hatching the [fish] sac fry are golden and fall through the egg basket and school in a tight cluster on the bottom of the tank. Sac fry do not need to be fed because they receive nourishment from the attached yolk sac. If a... fry-rearing trough is used, the sac fry are siphoned into a bucket using a [half-inch] hose and then transferred to the rearing trough. The yolk sac is absorbed by the fry in about 3 to 5 days, depending on water temperature.

CONT

When the yolk sac is almost completely absorbed, alevins begin to feed exogenously; this is … commonly referred to as "swim-up fry. "Unlike most species, salmonids have a functional stomach present before external feeding begins... Food taken at first feeding is related to the gape of the mouth, but also to prey abundance, size, availability, and mobility.

English

Subject field(s)
  • Animal Reproduction
  • Pregnancy
DEF

A membranous sac of most vertebrates that encloses the yolk, is attached in most forms(as in humans) through the yolk stalk with the intestinal cavity of the embryo, and is supplied with blood vessels that transport nutritive yolk products to the developing embryo.

OBS

In birds and reptiles, the yolk sac encloses the yolk; in most mammals, a fluid replaces the yolk.

Record 9 2012-01-16

English

Subject field(s)
  • Blood
CONT

The term hematopoiesis refers to the formation and development of the cells of the blood. In humans this process begins in the yolk sac in the first weeks of embryonic development. By the third month of gestation, stem cells migrate to the fetal liver and then to the spleen(between 3-7 mths these two organs play a major hempatopoietic role). Next, the bone marrow becomes the major hematopoietic organ and hematopoiesis ceases in the liver and spleen.

Key term(s)
  • blood-forming organ

  • Sang
DEF

Subject field(s)
  • The Genitals
DEF

An highly malignant germ cell tumor of the testis and ovary containing structures resembling those seen in the yolk sac and other embryogenic tissues.

OBS

Most adult cases occur as a component or mixed germ cell neoplasm. Pure forms present as infiltrative, homogenous, yellow-white mucinous lesions.

OBS

Variously called infantile embryonal carcinoma, mesonephroma, orchidoblastoma, testicular adenocarcinoma of the infancy, and endodermal sinus tumor. Most adult cases occur as a component or mixed germ cell neoplasm. Pure forms present as infiltrative, homogenous, yellow-white mucinous lesions.

French

Domaine(s)
  • Organes génitaux
DEF

Tumeur germinale maligne du testicule ou de l'ovaire.

CONT

La tumeur vitelline du testicule est encore appelée tumeur du sinus endodermique ou carcinome embryonnaire de type infantile, ou orchioblastome, ou adénocarcinome embryonnaire alors que la tumeur vitelline de l'ovaire ou tumeur du sinus endodermique, a été longtemps désignée sous le terme de mésonéphrome de Schiller ou de papillo-endothéliome ou de mésoblastome, en raison des ressemblances qu'on avait cru relever entre ses aspects histologiques et les glomérules du mésonéphrome, les proliférations endothéliales ou les mésoblastes de l'embryon.

OBS

La tumeur vitelline se développe plus souvent à l'état pur dans l'ovaire que dans le testicule.
