During development, the human midgut undergoes a rapid phase of growth in which the loop of midgut herniates outside of the abdominal cavity of the fetus and protrudes into the umbilical cord. This herniation is physiological (occurs normally). Later in development, the fetus's body catches up in size relative to the midgut and creates adequate room in the abdominal cavity for the entirety of the midgut to reside. The midgut loop… WebIntroduction. Many insect species are characterized by a high reproductive potential (Engel, 2015).Egg production of oviparous insects is a sequential process consisting of previtellogenic development, vitellogenesis, and choriogenesis (Telfer & Anderson, 1968).During vitellogenesis, the yolk protein precursor vitellogenin (Vg) is synthesized in …
