An imaginal disc is one of the parts of a holometabolous insect larva that will become a portion of the outside of the adult insect during the pupal transformation to the imago. [1] Contained within the body of the larva, there are pairs of discs that will form, for instance, the wings or legs or antennae or other structures in the adult.
In invertebrates, the wing imaginal disc of Drosophila provides an excellent model for the study of compartments. Although other tissues , such as the abdomen, [ 5 ] and even other imaginal discs are compartmentalized, much of our understanding of key concepts and molecular mechanisms involved in compartment boundaries has been derived from ...
Last molting of a cicada giving rise to the winged imago. In biology, the imago (Latin for "image") is the last stage an insect attains during its metamorphosis, its process of growth and development; it is also called the imaginal stage ("imaginal" being "imago" in adjective form), the stage in which the insect attains maturity.
The second that Mica Tenenbaum finished listening to the sequenced version of Imaginal Disk, the second full-length album from her electro-pop duo Magdalena Bay, she had to mark the occasion. She ...
Decapentaplegic (Dpp) is a key morphogen involved in the development of the fruit fly Drosophila melanogaster and is the first validated secreted morphogen. [1] It is known to be necessary for the correct patterning and development of the early Drosophila embryo and the fifteen imaginal discs, which are tissues that will become limbs and other organs and structures in the adult fly.
Drosophila embryogenesis, the process by which Drosophila (fruit fly) embryos form, is a favorite model system for genetics and developmental biology. The study of its embryogenesis unlocked the century-long puzzle of how development was controlled, creating the field of evolutionary developmental biology . [ 1 ]
The myth of a unified, integrated cultural system was also advanced by Western Marxists such as by Antonio Gramsci through the theory of cultural hegemony through a dominant culture. Basic to these mistaken conceptions was the idea of culture as a community of meanings, which function independently in motivating social behavior.
The original 1957 publication of Manual de zoología fantástica contained eighty-two entries. Thirty-four additional entries were added to the retitled second edition. While collaborating on the 1969 English translation, Borges revised many of the original entries and added another four, bringing the total count to
